CY74FCT16373ETPVCT

Latches Overview

The CY74FCT16373ETPVCT is a 16-bit transparent D-type latch manufactured by Texas Instruments. It features two independent 8-bit latches with 3-state outputs, housed in a 48-pin SSOP package. The device operates within a supply voltage range of 4.5V to 5.5V and supports an operating temperature range from -40°C to +85°C. Designed for high-speed applications, it provides low-power CMOS performance while maintaining compatibility with standard logic families.

Latches Feature Summary

• Provides 16-bit data storage capability through two independent 8-bit transparent D-type latches
• Features 3-state outputs to facilitate direct connection to system buses without external buffers
• Supports mixed 3.3V and 5V environments, allowing inputs to be driven by either voltage level

Latches Applications

• Memory address latching in embedded systems
• I/O port buffering for microcontroller interfaces
• Bus driver implementations requiring temporary data storage

Latches Procurement Notes

Verify the specific suffix 'E' against official Texas Instruments documentation, as standard listings typically reference 'C' or 'A' variants. Confirm RoHS compliance status and moisture sensitivity level (MSL) ratings prior to procurement. Ensure the SSOP-48 package dimensions match your PCB footprint requirements. Check for active manufacturing status or obsolescence notices directly from the manufacturer.

Latches Selection Notes

Select this component when a 16-bit transparent latch with 3-state outputs is required for bus interfacing. It is suitable for designs needing simultaneous 3.3V and 5V I/O compatibility. Consider the SSOP-48 package constraints regarding board space and thermal dissipation. Verify that the propagation delay characteristics meet the timing requirements of your specific clock domain.

Latches Part Context

This part belongs to the FCT (Fast CMOS Technology) family, known for high-speed operation and low power consumption. It serves as a bridge between microcontrollers and peripheral devices, ensuring stable data transfer. The 16-bit configuration allows for efficient handling of wide data words compared to 8-bit alternatives.

Latches Replacement Considerations

Direct substitutes include the CY74FCT16373ATPVCT and CY74FCT16373CTPVCT. Verify pinout and electrical specifications before swapping. Alternative technologies like SN74AVC16373 offer lower voltage support but differ in interface standards.
