SN74ACT563DWR

Overview

The SN74ACT563DWR is an octal transparent latch manufactured by Texas Instruments, belonging to the 74ACT 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 and supports a propagation delay of 11.5 ns. It draws a static current of 4 uA and provides a low-level output current of 32 mA alongside a high-level output current of -24 mA. Designed for surface-mount applications, it is housed in a 20-SOIC package and 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 to complement non-inverting system requirements
• Supports three-state output control for efficient bus-oriented architectures

Applications

• Parallel-to-serial data conversion circuits
• Bus-oriented memory register implementations
• Temporary data storage in digital processing systems

Procurement Notes

Verify the specific ordering suffix to confirm the tape and reel packaging configuration intended for automated assembly processes. Ensure that the component meets RoHS compliance standards required by your manufacturing facility. Cross-reference the datasheet specifications against your system's voltage and thermal constraints before finalizing procurement decisions.

Selection Notes

Select this component when designing systems requiring eight-bit parallel latching with inverting characteristics. It is suitable for applications needing moderate speed performance with standard CMOS drive capabilities. Consider the 20-SOIC package dimensions during PCB layout planning to ensure adequate spacing and thermal management for surface-mount assembly.

Part Context

This part belongs to the broader SN74ACT family of logic integrated circuits produced by Texas Instruments. It shares functional similarities with other octal latches like the SN74ACT573 but differs in its specific inverting output configuration. The ACT series offers improved switching speeds compared to older LS counterparts while maintaining compatibility with standard TTL input levels.

Replacement Considerations

SN74ACT563DBR serves as a direct pin-compatible alternative offering identical electrical characteristics in a different SSOP package format.
