M74HC563B1R

Latches Overview

The M74HC563B1R is an octal D-type transparent latch with tri-state outputs, manufactured by STMicroelectronics using silicon gate C2MOS technology. It operates within a supply voltage range of 2 V to 6 V and features through-hole mounting in a 20-DIP package. The device provides high-speed performance with a propagation delay of 12 ns and a current consumption of 7.8 mA. It includes inverted outputs and supports standard logic interfacing for digital data storage applications.

Latches Feature Summary

• Octal configuration providing eight independent D-type latching channels
• Tri-state output capability allowing bus-oriented connections
• High-speed CMOS fabrication ensuring low power consumption
• Transparent latch operation synchronized with the enable signal

Latches Applications

• Digital data storage systems requiring parallel input retention
• Bus interface circuits utilizing tri-state control
• Industrial control logic involving high-speed signal latching
• Consumer electronics employing 74HC series logic families

Latches Procurement Notes

Verify the specific suffix B1R corresponds to the 20-DIP through-hole package variant when sourcing. Confirm that the tri-state inverted output configuration matches the system design requirements. Ensure the operating voltage range of 2 V to 6 V aligns with the target circuit's power supply specifications before finalizing procurement orders.

Latches Selection Notes

Select this component when an octal latch with tri-state outputs is required for high-speed digital applications. The 20-DIP package suits prototyping and through-hole manufacturing processes. Consider the 2 V to 6 V supply range compatibility with existing logic levels. Verify that the inverted output polarity meets the downstream circuit expectations compared to non-inverted alternatives.

Latches Part Context

This part belongs to the 74HC563 family of octal latches produced by STMicroelectronics. It utilizes advanced C2MOS technology for improved speed and power efficiency compared to older logic families. The M74HC563B1R designation specifically identifies the commercial grade version with the DIP-20 packaging option, distinct from surface-mount or industrial temperature variants.

Latches Replacement Considerations

Compatible substitutes include other manufacturers' 74HC563 equivalents in DIP-20 packages. Verify pinout compatibility and electrical characteristics such as propagation delay and supply voltage ranges. Ensure the replacement maintains the tri-state inverted output functionality to avoid signal inversion errors in the existing design.
