74FCT563PC

Latches Overview

The 74FCT563PC is an octal transparent latch manufactured by National Semiconductor. It features a single channel with 8:8 circuit configuration and tri-state inverted outputs. The component utilizes FACT technology for high-speed operation, offering a propagation delay of 12 ns at 5 V. It operates within a supply voltage range of 4.5 V to 5.5 V and draws a static current of 8 uA. The device is housed in a 20-pin PDIP package and supports low-level output currents up to 24 mA.

Latches Feature Summary

• High-speed octal latch design utilizing FACT technology
• Buffered common Latch Enable and Output Enable inputs
• Tri-state inverted outputs for bus driving applications

Latches Applications

• Bus driver circuits requiring tri-state control
• Data storage in high-speed digital systems

Latches Procurement Notes

Verify the manufacturer designation as National Semiconductor or its successor entities when sourcing this component. Confirm the 20-PDIP package type matches your board layout requirements. Ensure the logic family specification aligns with your system's voltage and speed constraints before procurement.

Latches Selection Notes

Select this component for applications requiring octal latching with tri-state capabilities. The 12 ns propagation delay suits moderate-speed digital designs. Verify compatibility with 5 V logic levels and ensure sufficient drive current for connected loads. Consider the PDIP package for through-hole mounting needs.

Latches Part Context

This part belongs to the FCT logic series, known for CMOS performance with TTL compatibility. The 74FCT563 variant specifically provides octal latching functionality. It is distinct from shift registers or standard flip-flops by its transparent latch behavior controlled by enable signals.

Latches Replacement Considerations

Check for equivalents such as the 74FCT373PC, which offers similar octal latch functionality. Verify pinout compatibility and electrical specifications before substitution. Ensure the replacement maintains the required tri-state output characteristics and package form factor.
