74HCT573DB,112

Latches Overview

The Nexperia 74HCT573DB,112 is an octal D-type transparent latch with 3-state outputs. It features a latch enable (LE) input and a common output enable (OE) input. The device operates within a supply voltage range of 4.5 V to 5.5 V. Propagation delay from data inputs to outputs is typically 20 ns at 4.5 V. The component utilizes a 20-lead SSOP package.

Latches Feature Summary

• Transparent latch operation allows data to pass directly when enabled
• Common output enable input controls three-state bus orientation
• Inputs include clamp diodes for interfacing with voltages exceeding VCC

Latches Applications

• Microprocessor input or output port interfaces
• Bus-oriented applications requiring 3-state control
• Microcomputer memory address latching

Latches Procurement Notes

Verify the specific ordering suffix against current Nexperia documentation. Confirm that the requested part number matches the exact package type and temperature range required for the design. Check official distributor channels for availability as manufacturing status may change.

Latches Selection Notes

Select this component for designs requiring TTL-compatible logic levels with CMOS performance. Ensure the application environment stays within the specified -40 °C to +125 °C operating temperature range. Verify that the 20-SSOP package dimensions fit the PCB layout constraints.

Latches Part Context

This component belongs to the 74HCT series, which provides high-speed CMOS logic with TTL-compatible input levels. The 74HCT573 variant specifically implements an 8-bit latch function. It is designed for general-purpose digital logic applications in industrial and consumer electronics.

Latches Replacement Considerations

Nexperia 74HCT573PW,118 offers a TSSOP20 package alternative.
