SN74ACT563N

Overview

The SN74ACT563N 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 and supports through-hole mounting in a PDIP-20 package. Key electrical specifications include a propagation delay of 11.5 ns, static current of 4 uA, low-level output current of 32 mA, and high-level output current of -24 mA. It 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 temporary data storage
• Interface buffering between microprocessors and peripheral devices

Procurement Notes

Verify the specific package type and pinout configuration against your PCB layout requirements before procurement. Confirm that the operating voltage and temperature ranges align with your system design constraints. Ensure compatibility with existing logic families in your circuit. Check for any recent product change notifications or lifecycle status updates from the manufacturer to guarantee long-term availability.

Selection Notes

Select this component when an octal latch with inverting outputs is required in a through-hole design. Consider the ACT series performance characteristics regarding speed and power consumption relative to other logic families. Evaluate the PDIP-20 package suitability for your assembly process. Compare drive strength requirements against the specified output currents to ensure adequate load handling capabilities.

Part Context

This part belongs to the SN74ACT family of advanced CMOS logic devices, offering higher speed and lower power consumption compared to standard TTL equivalents. The SN74ACT563 specifically addresses applications requiring multiple latching channels in a single integrated circuit. It serves as a bridge between parallel data sources and serial processing systems within digital electronics.

Replacement Considerations

Check for SN74ACT563 variants with different packaging options such as SOIC or SSOP if surface mount technology is preferred. Verify cross-compatibility with other manufacturers' octal latches meeting similar electrical specifications.
