SN54F373J

Latches Overview

The SN54F373J is an octal D-type transparent latch manufactured by Texas Instruments, belonging to the SN54F logic series. It features eight independent D-type latches with true outputs and is housed in a 20-pin ceramic dual in-line package (CDIP). The device operates within a supply voltage range of 4.5 V to 5.5 V and supports a military-grade temperature range from -55°C to +125°C. Propagation delay is specified at 9 ns at 5 V, with a low-level output current capability of 24 mA.

Latches Feature Summary

• Provides eight independent transparent D-type latches for data storage applications
• Features high-speed F-series logic performance suitable for demanding environments
• Designed for military specifications with extended thermal operating capabilities

Latches Applications

• Military aerospace systems requiring robust logic components
• High-speed data bus buffering and registration
• Industrial control systems operating in extreme temperatures

Latches Procurement Notes

Verify the specific suffix J indicates the 20-lead ceramic CDIP package configuration. Confirm RoHS compliance status as military variants may differ from commercial standards. Ensure the ordering part number matches the required lead form and material specifications for your assembly process.

Latches Selection Notes

Select this component when high-speed switching and wide temperature tolerance are required. The SN54F series offers faster propagation than standard TTL but consumes more power. Consider the ceramic package for superior environmental resistance compared to plastic alternatives in harsh conditions.

Latches Part Context

This device is part of the SN54xx family designed for military applications. It complements other octal latches like the SN54LS374 or SN54AS374, offering a balance between speed and power consumption. The transparent latch architecture allows direct data passage when enabled, differing from edge-triggered flip-flops.

Latches Replacement Considerations

Compatible substitutes include SN54LS373 and SN54HC373 for lower power or CMOS applications. SN54AS373 offers higher speed but different pinout compatibility. Verify package dimensions and electrical characteristics before substitution.
