CY74FCT373ATSOCT

Latches Overview

The CY74FCT373ATSOCT is an octal transparent latch manufactured by Texas Instruments, belonging to the FCT logic series. It features eight non-inverting D-type inputs and three-state outputs housed in a QSOP-20 surface-mount package. The device operates within a supply voltage range of 4.75 V to 5.25 V and supports TTL input levels. Key electrical characteristics include a propagation delay of 5.2 ns at 5 V, with output drive capabilities of -32 mA for high-level and 32 mA for low-level currents. It functions reliably across an industrial temperature range from -40°C to +85°C.

Latches Feature Summary

• Provides octal latching functionality with transparent data path control
• Features three-state outputs for effective bus line driving and isolation
• Supports TTL-compatible input logic levels for direct interfacing

Latches Applications

• Parallel-to-serial data conversion circuits
• Bus-oriented memory register storage
• Temporary data holding in digital signal processing systems

Latches Procurement Notes

Verify the specific suffix ATSOCT to confirm the QSOP-20 package type and tape-and-reel packaging format. Ensure compatibility with the required operating temperature range and supply voltage specifications before integration. Cross-reference the manufacturer part number against official datasheets to validate pinout configurations and electrical ratings.

Latches Selection Notes

Select this component when an octal latch with three-state outputs is required for bus applications. The FCT series offers faster switching speeds compared to standard 74F logic while maintaining CMOS power efficiency. Consider the QSOP-20 package constraints regarding board space and thermal management during the design phase.

Latches Part Context

This part belongs to the CY74FCT373T family of octal transparent latches. It serves as a complementary device to other FCT logic components, providing data storage capabilities for system architectures requiring parallel data handling. The family is designed to replace slower legacy logic families in high-speed digital designs.
