CD54HCT373F3A

Latches Overview

The CD54HCT373F3A is a high-speed CMOS logic octal transparent latch with three-state outputs manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 5.5 V and features TTL-compatible inputs. The device is housed in a 20-CDIP ceramic package designed for through-hole mounting. It supports an extended operating temperature range from -55°C to +125°C, ensuring reliability in demanding environments.

Latches Feature Summary

• Octal transparent latch architecture providing eight independent data storage elements
• Three-state outputs enabling direct bus connections without external buffers
• TTL-compatible input thresholds simplifying interface with legacy digital systems

Latches Applications

• Military-grade data buffering applications requiring wide thermal stability
• High-speed CMOS logic systems utilizing parallel data transfer architectures
• Industrial control units necessitating robust ceramic packaging for harsh conditions

Latches Procurement Notes

Verify the specific suffix F3A indicates military-grade ceramic construction when sourcing. Confirm availability status as this component may be subject to limited distribution or special order requirements. Ensure compatibility with existing PCB footprints for 20-pin CDIP packages during integration planning.

Latches Selection Notes

Select this component for designs requiring octal latching with bus-driven output capabilities. Consider the CD54 series for superior radiation tolerance and thermal performance compared to commercial variants. Evaluate the 20-CDIP package constraints against available board space and mounting techniques.
