CY74FCT573TQCT

Latches Overview

The CY74FCT573TQCT is an octal D-type transparent latch manufactured by Texas Instruments, belonging to the FCT logic series. It features a single circuit with eight input and eight output lines housed in a 20-SSOP package. The device operates within a supply voltage range of 4.75 V to 5.25 V and supports surface mount installation. Key electrical specifications include a propagation delay of 8 ns at 5 V, with low-level and high-level output currents rated at 32 mA each. The component functions as a non-inverting latch with three-state outputs and maintains a working temperature range from -40°C to +85°C.

Latches Feature Summary

• Provides octal data storage via transparent latching functionality controlled by a single enable signal.
• Delivers strong drive capability through specified high and low output current ratings suitable for bus applications.
• Ensures signal integrity with defined propagation delay characteristics under standard operating conditions.

Latches Applications

• Parallel data buffering in digital systems
• Interface between microprocessors and peripheral devices
• Temporary data storage in memory architectures

Latches Procurement Notes

Verify the specific suffix TQC against official datasheets to confirm package type and moisture sensitivity level. Confirm RoHS compliance status directly with manufacturer documentation prior to integration. Ensure design compatibility with the required 20-SSOP footprint and thermal management guidelines for the specified operating temperature range.

Latches Selection Notes

Select this component when an octal latch with TTL-compatible inputs and CMOS outputs is required. The FCT series offers speed comparable to LS-TTL with lower power consumption. Verify that the 5V supply constraint aligns with system power rails and that the SSOP package fits the PCB layout constraints.

Latches Part Context

This part belongs to the Texas Instruments CY74FCT family, which combines Fast CMOS technology with TTL-compatible inputs. The 74FCT573 variant specifically provides eight-bit latching capabilities. It serves as a standard solution for parallel data handling in industrial and commercial electronic designs requiring reliable state retention.

Latches Replacement Considerations

Consult official substitution guides for equivalent parts within the 74FCT573 family. Verify pinout compatibility and electrical parameters before replacing. Generic equivalents may differ in package dimensions or drive strength.
