SN74ACT563PWR

Overview

The SN74ACT563PWR is an octal transparent latch manufactured by Texas Instruments, belonging to the SN74ACT logic series. It features eight D-type inputs and corresponding outputs with inverting polarity. The device operates within a supply voltage range of 4.5 V to 5.5 V. Key electrical specifications include a propagation delay of 11.5 ns, a static current of 4 uA, a low-level output current of 32 mA, and a high-level output current of -24 mA. It is housed in a 20-pin TSSOP package and supports surface mount installation. The component functions reliably across an operating temperature range from -40°C to +85°C.

Feature Summary

• Provides eight independent transparent latch channels for data storage applications
• Features inverting output polarity for signal inversion requirements
• Supports high-drive capability with specified low and high-level output currents

Applications

• Parallel-to-serial data conversion circuits
• Bus holding and buffering systems
• Digital data acquisition interfaces

Procurement Notes

Verify the specific suffix 'PWR' confirms the TSSOP-20 surface-mount package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor certificates prior to integration. Ensure the procurement channel provides valid traceability records for quality assurance purposes.

Selection Notes

Select this component when eight-channel latching functionality is required in a compact surface-mount form factor. The ACT series offers speed and drive characteristics suitable for standard 5V logic systems. Consider the TSSOP-20 package constraints regarding PCB space and thermal management during layout design.

Part Context

This part belongs to the SN74ACT family of advanced CMOS logic devices produced by Texas Instruments. The family is designed to replace older TTL equivalents while offering improved power consumption and switching speeds. The SN74ACT563 specifically addresses the need for multi-bit data retention in digital systems.

Replacement Considerations

Cross-reference with SN74ACT563DR for identical functionality in a SOIC-20 package. Verify pinout compatibility and electrical parameters against alternative octal latches from other manufacturers before substitution.
