74HCT541D,653

Overview

The Nexperia 74HCT541D,653 is an octal non-inverting buffer and line driver featuring three-state outputs. It operates within a supply voltage range of 4.5 V to 5.5 V. The device provides two active-low output enable inputs (OE1 and OE2) that force the outputs into a high-impedance state when asserted HIGH. Inputs include clamp diodes for interfacing with voltages exceeding VCC. It utilizes CMOS technology for low power dissipation and complies with JEDEC standards.

Feature Summary

• Features two independent active-low output enables for flexible bus management
• Includes input clamp diodes to support current limiting resistors for over-voltage interfacing
• Provides high noise immunity and robust latch-up performance

Applications

• Bus-oriented communications systems
• Clock drivers and buffering
• Memory address and data register driving

Procurement Notes

Verify the specific suffix '653' against the manufacturer's latest ordering information to confirm package type and tape/reel specifications. Confirm RoHS compliance status and check for any product change notices or lifecycle updates prior to finalizing procurement plans.

Selection Notes

Select this component when TTL-compatible logic levels are required for an octal buffer application. Ensure the design accommodates the specified 4.5 V to 5.5 V supply voltage range. Verify that the SOIC-20 package dimensions align with the target PCB layout constraints.

Part Context

This part belongs to the 74HCT series of logic integrated circuits manufactured by Nexperia. It is functionally compatible with standard 74HCT logic families but offers enhanced drive capabilities suitable for line driving applications. The D package denotes a plastic small outline package configuration.

Replacement Considerations

Cross-reference with other manufacturers offering 74HCT541 equivalents in SOIC-20 packages. Verify pinout compatibility and electrical characteristics match before substitution.
