SN74HCT573PW

SN74HCT573PW Description

The SN74HCT573PW from Texas Instruments is a high-speed 8-bit transparent D-type latch with 3-state outputs, designed for surface-mount applications in the 74HCT series. Operating within a 4.5V to 5.5V supply range, it features low-power CMOS technology while maintaining TTL compatibility, making it ideal for mixed-voltage systems. With a propagation delay of 25ns and balanced 6mA output current (both high and low), it ensures reliable signal integrity in high-speed data transfer applications. Packaged in a 20-pin TSSOP (Tube), it is RoHS3 compliant and REACH unaffected, suitable for environmentally conscious designs.

SN74HCT573PW Features

• 8-bit transparent latch with 3-state outputs for bus-oriented applications.
• Wide voltage range (4.5V–5.5V) and TTL-compatible inputs, ensuring interoperability in diverse systems.
• High output drive (6mA) for robust signal transmission.
• Low power consumption (HCT technology) with 25ns propagation delay, optimizing speed-power trade-offs.
• MSL 1 (Unlimited) moisture sensitivity, simplifying storage and handling.
• Industrial-grade reliability with EAR99 and ROHS3 compliance, meeting global regulatory standards.

SN74HCT573PW Applications

• Data bus buffering in microprocessors, FPGAs, and memory interfaces.
