MC74HC541ANG

Overview

The MC74HC541ANG is an octal 3-state non-inverting buffer and line driver manufactured by onsemi. It operates within a supply voltage range of 2.0 V to 6.0 V. The device features eight inputs and eight outputs, with propagation delays specified at 165 ns (at 2 V), 33 ns (at 4.5 V), and 28 ns (at 6 V). Output drive capability supports 15 LSTTL loads, with high-level output current of -7.8 mA and low-level output current of 7.8 mA. Static current is typically 8 µA, with a maximum operating power supply current of 160 µA. It functions in temperatures from -40°C to +85°C and utilizes a 20-pin SOIC package.

Procurement Notes

Verify the specific suffix 'AN' against the manufacturer's official datasheet to confirm pinout compatibility and electrical characteristics relative to other variants in the 74HC541 family. Ensure the procurement source provides valid RoHS compliance documentation and confirms the component status as active or obsolete prior to ordering.

Selection Notes

Select this component when designing circuits requiring octal signal buffering with high-impedance states. It is suitable for applications needing interface between CMOS, NMOS, and TTL logic families. Consider the 2V to 6V operating range and the specific propagation delay requirements at the target supply voltage during selection.

Part Context

This part belongs to the 74HC series of high-speed CMOS logic devices produced by onsemi. It serves as a non-inverting counterpart to the inverting 74HC540. The device is designed to replace lower-speed logic families while maintaining CMOS advantages such as low power consumption and high noise immunity.

Replacement Considerations

Compatible substitutes include MM74HC541MTC and MC74HC541AF. Verify pinout alignment and ensure the replacement variant meets the required temperature range and package specifications.
