M74HC563RM13TR

Latches Overview

The M74HC563RM13TR is an octal D-type transparent latch fabricated with silicon gate C2MOS technology. It features tri-state outputs controlled by a latch enable input and an output enable input. The device operates within a supply voltage range of 2V to 6V and supports propagation delays as low as 12ns. It is housed in a 20-SOP package and functions across an industrial temperature range from -55°C to +125°C.

Latches Feature Summary

• Octal configuration providing eight independent D-type latches in a single package
• Tri-state outputs allowing direct connection to bus-oriented systems
• Transparent latch operation controlled by dedicated enable inputs

Latches Applications

• Bus-oriented memory mapping
• Temporary storage for data buffers
• Parallel-to-serial conversion circuits

Latches Procurement Notes

Verify the specific suffix RM13TR against official STMicroelectronics documentation to confirm tape-and-reel packaging and pinout compatibility. Ensure the procurement channel provides valid RoHS compliance certificates. Cross-reference the manufacturer part number with authorized distributor databases to avoid counterfeit components, as this series may have multiple manufacturing revisions.

Latches Selection Notes

Select this component when an octal latch with tri-state capability is required for high-speed CMOS applications. The HC logic family ensures compatibility with standard TTL levels while offering lower power consumption. Verify that the 20-SOP package fits the PCB footprint constraints and that the operating voltage range aligns with the system's power supply rails.

Latches Part Context

This part belongs to the M74HC563 series of octal latches produced by STMicroelectronics. It utilizes advanced C2MOS technology for high speed and low power. The device is designed for robust performance in industrial environments, featuring wide operating temperature ranges and noise immunity typical of the HC logic family.

Latches Replacement Considerations

Compatible substitutes include the M74HC573RM13TR, which shares similar packaging and logic functionality but may differ in internal latch transparency characteristics. Verify electrical parameters and pin configurations before substitution.
