CY74FCT2573ATQCTG4

Latches Overview

The CY74FCT2573ATQCTG4 is an octal D-type transparent latch manufactured by Texas Instruments. It operates within a supply voltage range of 4.75 V to 5.25 V and features non-inverting outputs with a low-level output current of 32 mA and a high-level output current of -15 mA. The device exhibits a propagation delay of 4.7 ns at 5 V and consumes 200 uA of operating power. It supports surface mount installation in a QSOP-20 package and functions reliably across a temperature range of -40°C to +85°C.

Latches Feature Summary

• Octal configuration providing eight independent data latching channels
• Transparent latch operation allowing direct data passage when enabled
• Non-inverting output polarity for straightforward signal interfacing

Latches Applications

• Parallel-to-serial data conversion circuits
• Bus holding applications requiring temporary data storage
• Interface buffering between microprocessors and peripheral devices

Latches Procurement Notes

Verify the specific suffix G4 indicates lead-free compliance and RoHS standards before procurement. Confirm the QSOP-20 package dimensions match your PCB footprint requirements. Ensure the operating voltage aligns with your system's 5V logic levels. Check moisture sensitivity handling instructions during assembly to prevent package damage.

Latches Selection Notes

Select this component when an octal latch with fast 4.7 ns propagation delay is required. It suits designs needing high drive capability with 32 mA low-level output current. Consider it for systems operating strictly within the 4.75 V to 5.25 V supply range. Evaluate thermal performance if multiple units operate near the upper temperature limit.

Latches Part Context

This part belongs to the FCT logic family, designed for high-speed CMOS applications. It complements other multiplexers and drivers in the series. The device integrates standard latch functionality with robust output stages suitable for driving moderate loads in digital logic systems.

Latches Replacement Considerations

Check for CY74FCT2573T variants or E4/G4 suffix versions for equivalent electrical specifications. Verify package compatibility if substituting with similar octal latches from other manufacturers.
