74HCT573PW,118

Latches Overview

The Nexperia 74HCT573PW,118 is an octal D-type transparent latch featuring three-state outputs, housed in a 20-TSSOP package. It operates within a supply voltage range of 4.5 V to 5.5 V. Key electrical parameters include a propagation delay of 17 ns and a static current of 8 uA. The device supports high-level output currents of -6 mA and functions reliably across an operating temperature range from -40 °C to +125 °C.

Latches Feature Summary

• Features eight D-type transparent latches with tri-state outputs for bus-oriented applications.
• Includes dedicated latch enable (LE) and active-low output enable (OE) inputs for precise data control.
• Inputs incorporate clamp diodes to facilitate interfacing with voltages exceeding VCC using current-limiting resistors.

Latches Applications

• Microprocessor and microcomputer input/output port expansion
• Bus-oriented digital circuit designs requiring data storage
• General-purpose latch applications in TTL-compatible logic systems

Latches Procurement Notes

Verify the specific suffix '118' corresponds to the TSSOP-20 reel or cut tape packaging configuration required for your assembly line. Confirm RoHS compliance status and lead times directly with authorized distributors, as production cycles may vary. Ensure the component matches the HCT logic family requirements for your system's voltage levels before finalizing orders.

Latches Selection Notes

Select this component when TTL-level input compatibility is required alongside CMOS performance characteristics. The 74HCT573PW,118 is suitable for designs needing wide operating temperatures up to +125 °C. Consider the 20-TSSOP package constraints regarding pin pitch and board space compared to alternative packages like SSOP or SO.

Latches Part Context

This part belongs to the 74HCT series of logic integrated circuits manufactured by Nexperia. It serves as a standard solution for storing 8-bit data in digital systems. The PW suffix indicates the TSSOP20 package variant, distinguishing it from other physical form factors within the same logical function family.
