These devices feature inputs and outputs on opposite sides of the package to facilitate printed circuit board layout. The 3-state control gate is a two-input AND gate with active-low inputs. If either output-enable (OE1 or OE2) input is high, all corresponding outputs are in the high-impedance state. The outputs provide noninverted data when they are not in the high-impedance state. To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pullup resistor. The minimum value of the resistor is determined by the current-sinking capability of the driver. 8.2 Functional Block Diagram 1 OE1 OE2 A1 19 2 18 Y1 To Seven Other Channels 8.3 Feature Description The SNx4AHC541 has a wide operating voltage range of 2 V to 5.5 V. It allows down voltage translations while accepting input voltages of up to 5.5 V. The slow edges of the SNx4AHC541 enables the reduction of output ringing. 8.4 Device Functional Modes Table 1 lists the functional modes for the SNx4AHC541 devices. 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. 9.1 Application Information The SN74AHC541 is a low-drive CMOS device that can be used for a multitude of bus interface type applications where output ringing is a concern. The low drive and slow edge rates will minimize overshoot and undershoot on the outputs. The inputs accept voltages up to 5.5 V, which allows down translation to the VCC level. Figure 4 shows how the slower edges can reduce ringing on the output compared to higher drive parts like AC. 9.2 Typical Application Regulated 5.0 V OE VCC A1 Y1 A8 Y8 µC or 5-V µC System logic LEDs System Logic GND Figure 3. Typical Application Schematic 9.2.1 Design Requirements This device uses CMOS technology and has balanced output drive. Take care 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. 9.2.2 Detailed Design Procedure 1. Recommended Input Conditions: – For rise time and fall time specifications, 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 5.5 V at any valid VCC. 2. Recommended Output Conditions: – Load currents should not exceed 25 mA per output and 75 mA total for the part. – Outputs should not be pulled above VCC. 10 Submit Documentation Feedback Copyright © 1995–2015, Texas Instruments Incorporated Product Folder Links: SN74AHC541 SN54AHC541 SN74AHC541, SN54AHC541 www.ti.com SCLS261O – OCTOBER 1995 – REVISED SEPTEMBER 2015 Typical Application (continued) 9.2.3 Application Curve 4 Voltage (V) 3 2 1 A1 Y1 0 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 Time (ns) C001 Vcc = 3.3 V, CL = 15 pF, TA = 25°C Figure 4. Simulated Propagation Delay From Input (A1) to Output (Y1) 10 Power Supply Recommendations The power supply can be any voltage between the minimum and maximum 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, 0.1 μF is recommended. If there are multiple VCC terminals then 0.01 μF or 0.022 μF is recommended for each power terminal. It is acceptable to parallel multiple bypass caps to reject different frequencies of noise. A 0.1 μF and 1 μF are commonly used in parallel. The bypass capacitor should be installed as close to the power terminal as possible for best results. 11 Layout 11.1 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 the Figure 5 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. It is acceptable to float outputs unless the part is a transceiver. If the transceiver has an output enable pin, it will disable the outputs section of the part when asserted. This will not disable the input section of the I/Os so they also cannot float when disabled. 11.2 Layout Example Vcc Input Unused Input Output Unused Input Output Input Figure 5.

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
