74HC563D,653

Latches Overview

The 74HC563D,653 is an octal D-type transparent latch featuring three-state outputs and inverting logic. Manufactured by NXP USA Inc., it belongs to the 74HC CMOS logic family. The device provides eight independent D-type inputs with a common Latch Enable (LE) input and a common Output Enable (OE) input. It operates within a supply voltage range of 2 V to 6 V. The component is housed in a 20-pin SOIC package.

Latches Feature Summary

• Octal D-type transparent latch architecture with inverting outputs
• Three-state output capability for bus-oriented applications
• Common latch enable and output enable control signals

Latches Applications

• Microprocessor memory interface circuits
• Bus-oriented data storage systems
• Industrial control logic interfaces

Latches Procurement Notes

Verify the specific ordering code 74HC563D,653 against official NXP documentation to confirm pinout compatibility and electrical specifications. Ensure the procurement source provides valid traceability for the Nexperia/NXP product line. Cross-reference the datasheet revision to validate operating temperature ranges and package dimensions prior to integration into design files.

Latches Selection Notes

Select this component when designing systems requiring parallel data latching with tri-state isolation. The inverting output characteristic distinguishes it from non-inverting counterparts like the 74HC573. Verify that the HC series speed and drive current meet the system requirements compared to HCT or AHC variants.

Latches Part Context

This part is part of the 74HC logic family, designed for high-speed CMOS operations. It serves as a fundamental building block for digital data storage and transfer in microcomputer systems. The device complements other octal latches in the series, offering specific inversion properties for signal routing flexibility.

Latches Replacement Considerations

The 74HC573D,653 is a non-inverting equivalent. For direct functional replacement with inverted outputs, verify pin-to-pin compatibility with other 74HC563 variants from different manufacturers.
