CY74FCT16373CTPAC

Latches Overview

The CY74FCT16373CTPAC is a CMOS latch from the FCT series, manufactured by Texas Instruments. It features two independent circuits, each handling eight bits for a total of sixteen lines. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports a propagation delay of 4.2 ns at 5 V. It utilizes a TSSOP-48 package with surface mount installation. The component provides non-inverting outputs with a low-level output current of 32 mA and a high-level output current of -32 mA. Static current consumption is specified at 500 uA, while maximum power supply current reaches 5 uA. Operating temperatures span from -40°C to +85°C.

Latches Feature Summary

• Provides dual-channel architecture with sixteen-bit data storage capability
• Features tri-state outputs for bus-oriented memory applications
• Supports transparent latch operation with positive-edge triggering

Latches Applications

• Bus-oriented memory implementations
• Clocked registers in digital systems
• Portable equipment requiring low power consumption

Latches Procurement Notes

Verify manufacturer origin as Texas Instruments despite the Cypress designation in legacy naming conventions. Confirm RoHS compliance status and check for End-of-Life notices, as this component may be obsolete. Ensure the TSSOP-48 package matches the target PCB footprint and validate moisture sensitivity levels before procurement.

Latches Selection Notes

Select this component for designs requiring high-speed latching with significant drive capability. The FCT logic family offers compatibility with standard TTL inputs while maintaining CMOS noise immunity. Consider the 4.5 V to 5.5 V operating range when designing power supplies. Evaluate thermal performance within the industrial temperature range if deployed in harsh environments.

Latches Part Context

This part belongs to the 74FCT16373T series of high-speed CMOS logic devices. It is functionally equivalent to other variants in the FCT latch family, differing primarily in packaging and suffix designations. The device represents a transition technology between older Schottky TTL and modern fast CMOS families, offering improved speed over standard 74LS counterparts.

Latches Replacement Considerations

Public confirmed substitute part numbers include CD74FCT16373TMT and 74FCT16373CTPAG.
