The output level is referenced to the supply voltage and is able to support 1.8-V, 2.5-V, 3.3-V, and 5-V CMOS levels. The input is designed with a lower threshold circuit to match 1.8 V input logic at VCC = 3.3 V and can be used in 1.8 V to 3.3 V level-up translation. In addition, the 5 V tolerant input pins enable down translation (that is, 3.3 V to 2.5 V output at VCC = 2.5 V). The wide VCC range of 1.8 V to 5.5 V allows generation of desired output levels to connect to controllers or processors. The SN74LV1T32 device is designed with current-drive capability of 8 mA to reduce line reflections, overshoot, and undershoot caused by high-drive outputs. 9.2 Functional Block Diagram A B 1 4 2 Y Figure 9-1. Logic Diagram 9.3 Feature Description 9.3.1 Clamp Diode Structure The outputs to this device have both positive and negative clamping diodes, and the inputs to this device have negative clamping diodes only as depicted in Figure 9-2. CAUTION Voltages beyond the values specified in the Absolute Maximum Ratings table can cause damage to the device. The input and output voltage ratings may be exceeded if the input and output clampcurrent ratings are observed. Device VCC +IOK Input Output Logic -IIK -IOK GND Figure 9-2. Electrical Placement of Clamping Diodes for Each Input and Output 9.3.2 Balanced CMOS Push-Pull Outputs This device includes balanced CMOS push-pull outputs. The term balanced indicates that the device can sink and source similar currents. The drive capability of this device may create fast edges into light loads so routing and load conditions should be considered to prevent ringing. Additionally, the outputs of this device are capable of driving larger currents than the device can sustain without being damaged. It is important for the output power of the device to be limited to avoid damage due to overcurrent. The electrical and thermal limits defined in the Absolute Maximum Ratings must be followed at all times. Unused push-pull CMOS outputs should be left disconnected. 10 Submit Document Feedback Copyright © 2022 Texas Instruments Incorporated Product Folder Links: SN74LV1T32 SN74LV1T32 www.ti.com SCLS741B – NOVEMBER 2013 – REVISED JUNE 2022 9.3.3 LVxT Enhanced Input Voltage The SN74LV1T32 belongs to TI's LVxT family of Logic devices with integrated voltage level translation. This family of devices was designed with reduced input voltage thresholds to support up-translation, and inputs tolerant of signals with up to 5.5 V levels to support down-translation. The output voltage will always be referenced to the supply voltage (VCC), as described in the Electrical Characteristics table. To ensure proper functionality, input signals must remain at or below the specified VIH(MIN) level for a HIGH input state, and at or below the specified VIL(MAX) for a LOW input state. Figure 9-3 shows the typical VIH and VIL levels for the LVxT family of devices, as well as the voltage levels for standard CMOS devices for comparison. The inputs are high impedance and are typically modeled as a resistor in parallel with the input capacitance given in the Electrical Characteristics. The worst case resistance is calculated with the maximum input voltage, given in the Absolute Maximum Ratings, and the maximum input leakage current, given in the Electrical Characteristics, using Ohm's law (R = V ÷ I). The inputs require that input signals transition between valid logic states quickly, as defined by the input transition time or rate in the Recommended Operating Conditions table. Failing to meet this specification will result in excessive power consumption and could cause oscillations. More details can be found in the Implications of Slow or Floating CMOS Inputs application report. Do not leave inputs floating at any time during operation. Unused inputs must be terminated at VCC or GND. If a system will not be actively driving an input at all times, a pull-up or pull-down resistor can be added to provide a valid input voltage during these times. The resistor value will depend on multiple factors; however, a 10-kΩ resistor is recommended and will typically meet all requirements. 3.6 3.4 3.3-V CMOS 3.2 VIH 3 VIL HIGH Input 2.8 LOW Input 2.6 2.5-V CMOS 2.4 2.4 V (VOH) VIN - Input Voltage (V) 2.2 2 2 V (VOH) 1.8-V CMOS 1.8 1.6 1.45 V (VOH) 1.4 1.2 1.2-V CMOS 1.1 V (VOH) 1 0.8 0.6 0.45 V (VOL) 0.4 0.4 V (VOL) 0.4 V (VOL) 0.3 V (VOL) 0.2 0 1.6 1.8 2 2.2 2.4 2.6 2.8 3 3.2 3.4 3.6 3.8 4 4.2 4.4 4.6 4.8 5 5.2 5.5 VCC - Supply Voltage (V) Figure 9-3. LVxT Input Voltage Levels 9.3.3.1 Down Translation Signals can be translated down using the SN74LV1T32. The voltage applied at the VCC will determine the output voltage and the input thresholds as described in the Recommended Operating Conditions and Electrical Characteristics tables. When connected to a high-impedance input, the output voltage will be approximately VCC in the HIGH state, and 0 V in the LOW state. Ensure that the input signals in the HIGH state are between VIH(MIN) and 5.5 V, and input signals in the LOW state are lower than VIL(MAX) as shown in Figure 9-3. For example, standard CMOS inputs for devices operating at 5.0 V, 3.3 V or 2.5 V can be down-translated to match 1.8 V CMOS signals when operating from 1.8-V VCC. See Figure 9-4.

The voltage applied at VCC will determine the output voltage and the input thresholds as described in the Recommended Operating Conditions and Electrical Characteristics tables. When connected to a high-impedance input, the output voltage will be approximately VCC in the HIGH state, and 0 V in the LOW state. The inputs have reduced thresholds that allow for input high-state levels which are much lower than standard values. For example, standard CMOS inputs for a device operating at a 5-V supply will have a VIH(MIN) of 3.5 V. For the SN74LV1T32, VIH(MIN) with a 5-V supply is only 2 V, which would allow for up-translation from a typical 2.5-V to 5-V signals. Ensure that the input signals in the HIGH state are above VIH(MIN) and input signals in the LOW state are lower than VIL(MAX) as shown in Figure 9-4.

Each VCC terminal should have a good bypass capacitor to prevent power disturbance. A 0.1-μF capacitor is recommended for this device. It is acceptable to parallel multiple bypass caps to reject different frequencies of noise. The 0.1-μF and 1-μF capacitors are commonly used in parallel. The bypass capacitor should be installed as close to the power terminal as possible for best results, as shown in the following layout example. 11 Layout 11.1 Layout Guidelines When using multiple-input and multiple-channel logic devices inputs must not ever be left floating. In many cases, functions or parts of functions of digital logic devices are unused; for example, when only two inputs of a triple-input AND gate are used or only 3 of the 4 buffer gates are used. Such unused input pins must not be left unconnected because the undefined voltages at the outside connections result in undefined operational states. All unused inputs of digital logic devices must be connected to a logic high or logic low voltage, as defined by the input voltage specifications, to prevent them from floating. The logic level that must be applied to any particular unused input depends on the function of the device. Generally, the inputs are tied to GND or VCC, whichever makes more sense for the logic function or is more convenient.

LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect. NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design. PREVIEW: Device has been announced but is not in production. Samples may or may not be available. OBSOLETE: TI has discontinued the production of the device. (2) RoHS: TI defines "RoHS" to mean semiconductor products that are compliant with the current EU RoHS requirements for all 10 RoHS substances, including the requirement that RoHS substance do not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, "RoHS" products are suitable for use in specified lead-free processes. TI may reference these types of products as "Pb-Free". RoHS Exempt: TI defines "RoHS Exempt" to mean products that contain lead but are compliant with EU RoHS pursuant to a specific EU RoHS exemption. Green: TI defines "Green" to mean the content of Chlorine (Cl) and Bromine (Br) based flame retardants meet JS709B low halogen requirements of
