Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify part status as obsolete and not in production. Confirm package type matches 20-DIP specifications. Ensure compatibility with existing 2V-6V supply rails. Check for RoHS compliance documentation if required by current manufacturing standards. Validate supplier authenticity due to discontinued status.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component only when legacy 74ACQ series compatibility is mandatory. Consider the quiet output feature for noise reduction requirements. Verify that the 20-pin DIP package fits the target PCB layout. Assess availability constraints given the obsolete lifecycle status. Evaluate alternative modern equivalents if new designs are permitted.

Buffers, Drivers, Receivers, Transceivers Part Context

This device is part of the 74ACQ family from Fairchild Semiconductor, designed for high-speed logic applications with low noise emissions. The ACQ series combines AC speed with Q-series quiet output characteristics. It serves as a direct replacement for standard 74AC245 devices where noise performance is critical. The component supports bidirectional data flow across eight bits simultaneously.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Public confirmed substitutes include SN74AS574DWE4 and DM74AS574WMX. These alternatives offer similar functionality but may differ in electrical specifications or package types. Verify pinout compatibility before substitution. Cross-reference datasheets for voltage and speed differences.
