CD54AC373F3A

Latches Overview

The CD54AC373F3A is an octal transparent latch manufactured by Harris Corporation, housed in a 20-lead ceramic dual in-line package (CDIP). It features true outputs with three-state capability and operates on a single supply voltage of 5 V. The device supports a load capacitance of 50 pF and functions within a temperature range of -55 °C to 125 °C.

Latches Feature Summary

• Octal configuration providing eight independent data latching channels
• Three-state output structure enabling bus-driven system architectures
• Transparent latch operation allowing direct data passage when enabled
• Ceramic glass-sealed packaging designed for high-reliability environments

Latches Applications

• High-reliability military aerospace systems requiring radiation tolerance
• Industrial control interfaces demanding wide operating temperature stability
• Data acquisition systems utilizing bus-driven memory structures
• Communication equipment requiring robust signal latching capabilities

Latches Procurement Notes

Verify the manufacturer origin, as Texas Instruments acquired Harris Semiconductor assets. Confirm the specific suffix F3A denotes the ceramic DIP variant. Ensure compliance with legacy procurement requirements for military-grade components. Check for availability constraints due to discontinued status or limited production runs from original sources.

Latches Selection Notes

Select this component for applications necessitating octal latching with three-state outputs in harsh environments. The ceramic package provides superior thermal and mechanical stability compared to plastic alternatives. Consider the 5 V supply requirement and ensure interface compatibility with existing logic families. Evaluate the need for radiation hardness if deploying in space or high-altitude contexts.

Latches Part Context

This part belongs to the AC series of CMOS logic devices, characterized by high-speed operation and low power consumption. The CD54 prefix indicates military-grade qualification standards. The device serves as a fundamental building block for digital storage and data buffering in complex integrated circuits.

Latches Replacement Considerations

The CD54AC373N is a plastic DIP equivalent. The CD74AC373E offers a similar function in a different package style. Verify pinout compatibility and electrical specifications before substituting with these variants.
