CD74FCT373SM

Latches Overview

The CD74FCT373SM is an octal transparent latch manufactured by Harris Corporation, belonging to the FCT logic series. It features true outputs and utilizes CMOS technology within a surface-mount SSOP-20 package. The device operates with a supply voltage range of 4.5V to 5.5V and supports a load capacitance of 50 pF. It includes bus hold inputs to eliminate external pull-up resistors and provides three-state output characteristics with series resistance. The component functions as a single-function, 8-bit driver suitable for high-speed digital applications.

Latches Feature Summary

• Bus hold inputs eliminate the need for external pull-up resistors
• Three-state outputs with series resistance for improved signal integrity
• CMOS technology providing low power consumption

Latches Applications

• High-speed data bus buffering
• Octal transparent latch storage in digital systems
• Interface circuits requiring three-state control

Latches Procurement Notes

Verify the manufacturer origin, as Harris Corporation's logic assets were acquired by Texas Instruments. Confirm the specific suffix 'SM' corresponds to the SSOP-20 package and ensure RoHS compliance status matches project requirements, as older Harris parts may not meet current environmental standards. Cross-reference datasheets from both Harris and Texas Instruments for accurate pinout and electrical specifications.

Latches Selection Notes

Select this component when a fast, octal latch with three-state outputs is required in a compact surface-mount form factor. The FCT series offers speed advantages over standard HC/HCT logic while maintaining CMOS power efficiency. Ensure the system operates within the 4.5V to 5.5V supply range and that the 50 pF load capacitance rating is sufficient for the connected traces.

Latches Part Context

This part belongs to the CD74FCT family of high-speed CMOS logic devices originally produced by Harris Corporation. The FCT series was designed to bridge the performance gap between standard TTL and faster ECL technologies. Harris Corporation was a significant manufacturer of these components before its semiconductor division was acquired, leading to subsequent production by Texas Instruments under similar naming conventions.
