CD74HCT541M96E4

Overview

The CD74HCT541M96E4 is an octal buffer and line driver from Texas Instruments, belonging to the HCT logic series. It features eight non-inverting inputs and outputs housed in a 20-pin SOIC package. The device operates within a supply voltage range of 4.5 V to 5.5 V. Key electrical specifications include a high-level output current of -6 mA and a low-level output current of 6 mA. Static current consumption is 8 uA, with a maximum operating temperature of +125 C.

Feature Summary

• Provides three-state output control for bus-oriented applications
• Compatible with standard CMOS logic levels via HCT input structure
• Supports surface-mount installation in compact SOIC-20 packages

Applications

• Bus-oriented systems requiring signal buffering
• Memory address drivers
• Clock distribution circuits

Procurement Notes

Verify the specific suffix E4 indicates lead-free compliance and RoHS status against the manufacturer's latest documentation. Confirm the M96 suffix corresponds to the correct tape-and-reel packaging configuration intended for automated assembly processes. Ensure the ordering part number matches the exact pinout and electrical characteristics required by the design specification.

Selection Notes

Select this component when designing systems that require high-speed CMOS performance with TTL-compatible input thresholds. The HCT series ensures compatibility with older 5V logic families while offering improved speed over standard HC devices. Consider the thermal management requirements given the wide operating temperature range up to 125 C for industrial or automotive environments.

Part Context

This component is part of the CD74HCT541 family of octal buffers. It serves as a fundamental building block for digital logic interfaces, providing isolation and drive capability between different sections of a circuit board. The device is widely used in computing and telecommunications equipment where reliable signal transmission is critical.

Replacement Considerations

Check for CD74HCT541M96 as a potential variant without the E4 suffix, ensuring functional equivalence. Verify cross-compatibility with other manufacturers' 74HCT541 equivalents if supply constraints exist.
