The SN74LVC245A device is designed for asynchronous communication between data buses. This device transmits data from the A bus to the B bus or from the B bus to the A bus, depending on the logic level at the direction-control (DIR) input. The output-enable (OE) input can be used to disable the device so the buses effectively are isolated. To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pull-up resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver. Inputs can be driven from either 3.3-V or 5-V devices. This feature allows the use of this device as a translator in a mixed 3.3-V/5-V system environment. This device is fully specified for partial-power-down applications using Ioff. The Ioff circuitry disables the outputs, preventing damaging current backflow through the device when it is powered down. 9.2 Functional Block Diagram 1 DIR 19 OE A1 2 18 B1 To Seven Other Channels Pin numbers shown are for the DB, DGV, DW, N, NS, PW, and RGY packages. 9.3 Feature Description • • Allows down voltage translation – 5 V to 3.3 V – 5 V or 3.3 V to 1.8 V Inputs accept voltage levels up to 5.5 V 9.4 Device Functional Modes Table 1.

TI’s customers are responsible for determining suitability of components for their purposes. Customers should validate and test their design implementation to confirm system functionality. 10.1 Application Information SN74LVC245A is a high drive CMOS device that can be used for a multitude of bus interface type applications where output drive or PCB trace length is a concern. The inputs can accept voltages to 5.5 V at any valid VCC making it ideal for down translation. 10.2 Typical Application Regulated 1.8 V Regulated 1.65 V to 3.6 V Regulated 5 V SN74LVC245A 1OE A1 uC SN74LVC245A 1OE VCC DIR A1 B1 VCC DIR B1 uC System Logic LEDs/Relays or Other System Boards A8 B8 uC System Logic LEDs/Relays uC System Logic LEDs/Relays A8 GND B8 GND Figure 4. Typical Application Schematic 10.2.1 Design Requirements This device uses CMOS technology and has balanced output drive. Care should be taken to avoid bus contention because it can drive currents that would exceed maximum limits. The high drive will also create fast edges into light loads so routing and load conditions should be considered to prevent ringing. 10.2.2 Detailed Design Procedure 1. Recommended Input Conditions – For rise time and fall time specifcations, see (Δt/ΔV) in the Recommended Operating Conditions table. – For specified high and low levels, see (VIH and VIL) in the Recommended Operating Conditions table. – Inputs are overvoltage tolerant allowing them to go as high as (VI max) in the Recommended Operating Conditions table at any valid VCC. 2. Recommend Output Conditions – Load currents should not exceed (IO max) per output and should not exceed (Continuous current through VCC or GND) total current for the part. These limits are located in the Absolute Maximum Ratings table. – Outputs should not be pulled above VCC. 10 Submit Documentation Feedback Copyright © 1993–2015, Texas Instruments Incorporated Product Folder Links: SN74LVC245A SN74LVC245A www.ti.com SCAS218X – JANUARY 1993 – REVISED JANUARY 2015 Typical Application (continued) 10.2.3 Application Curves 100 80 60 TA = 25°C, VCC = 3 V, VIH = 3 V, VIL = 0 V, All Outputs Switching 40 TA = 25°C, VCC = 3 V, VIH = 3 V, VIL = 0 V, All Outputs Switching 20 I OH – mA I OL – mA 60 40 0 –20 –40 20 –60 0 –80 –20 –0.2 0.0 0.2 0.4 0.6 0.8 1.0 1.2 1.4 1.6 –100 –1 –0.5 0.0 VOL – V 0.5 1.0 1.5 2.0 2.5 3.0 3.5 4.0 VOH – V Figure 5.

Output Drive Current (IOH) vs HIGH-level Output Voltage (VOH) 11 Power Supply Recommendations The power supply can be any voltage between the MIN and MAX supply voltage rating located in the Recommended Operating Conditions table. Each VCC terminal should have a good bypass capacitor to prevent power disturbance. For devices with a single supply, a 0.1 μF capacitor is recommended. If there are multiple VCC terminals then 0.01 μF or 0.022 μF capacitors are recommended for each power terminal. It is ok to parallel multiple bypass capacitors to reject different frequencies of noise. Multiple bypass capacitors may be paralleled to reject different frequencies of noise. The bypass capacitor should be installed as close to the power terminal as possible for the best results. 12 Layout 12.1 Layout Guidelines When using multiple bit logic devices, inputs should not float. In many cases, functions or parts of functions of digital logic devices are unused. Some examples are when only two inputs of a triple-input AND gate are used, or when only 3 of the 4-buffer gates are used. Such input pins should not be left unconnected because the undefined voltages at the outside connections result in undefined operational states. Specified in Figure 7 are rules that must be observed under all circumstances. All unused inputs of digital logic devices must be connected to a high or low bias to prevent them from floating. The logic level that should be applied to any particular unused input depends on the function of the device. Generally they will be tied to GND or VCC, whichever makes more sense or is more convenient. 12.2 Layout Example VCC Unused Input Input Output Unused Input Output Input Figure 7.

The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates. 13.3 Glossary SLYZ022 — TI Glossary.
