CD74HC533E

Latches Overview

The CD74HC533E is a high-speed CMOS logic octal inverting transparent latch with three-state outputs manufactured by Harris Corporation. It operates within a supply voltage range of 2 V to 6 V and supports an operating temperature range from -55°C to 125°C. The device features eight bits, a maximum propagation delay of 35 ns at nominal voltage, and a maximum output current of 7.8 mA. It utilizes HC technology family and is available in a PDIP-20 package.

Latches Feature Summary

• Octal inverting transparent latch architecture
• Three-state output capability
• High-speed CMOS technology
• Wide operating temperature range

Latches Applications

• Data storage registers
• Buffer memory applications
• Parallel-to-serial data conversion

Latches Procurement Notes

Verify the manufacturer designation as Harris Corporation rather than Texas Instruments, as legacy documentation may attribute the part to different entities. Confirm the specific suffix 'E' indicates the PDIP-20 through-hole package variant. Ensure compatibility with standard 74HC logic families for pinout and electrical characteristics when integrating into existing designs.

Latches Selection Notes

Select this component for applications requiring octal data latching with inverting functionality and tri-state control. The wide voltage range of 2 V to 6 V allows flexibility in power supply design. Consider the 35 ns propagation delay for timing constraints and ensure the 7.8 mA drive current meets load requirements. Verify thermal performance within the specified -55°C to 125°C industrial temperature range.

Latches Part Context

This component belongs to the 74HC series of high-speed CMOS logic devices. It serves as an octal latch, distinct from flip-flops by its transparency during the enable phase. The device is part of the broader digital logic family used for temporary data storage and signal buffering in digital systems.

Latches Replacement Considerations

Compatible substitutes include the SN74HC533 and CD74HC533M. Verify pinout compatibility and electrical specifications before substitution.
