74HC563D,652

Latches Overview

The NXP 74HC563D,652 is an octal D-type transparent latch featuring three-state outputs and inverting logic. It operates within a supply voltage range of 2.0 V to 6.0 V and supports input levels compatible with both CMOS and TTL standards. The device utilizes a 20-pin SO package for surface-mount installation. It functions reliably across an extended temperature range from -40 °C to +125 °C, ensuring stable performance in demanding electronic environments.

Latches Feature Summary

• Octal configuration providing eight independent D-type transparent latches on a single integrated circuit
• Three-state output capability allowing direct connection to bus systems without external drivers
• Inverting logic design where the output reflects the complement of the data input when enabled

Latches Applications

• High-speed data buffering in digital communication interfaces
• Temporary storage of parallel data in microprocessor-based control systems
• Address latching for memory decoding in computer architecture

Latches Procurement Notes

Verify the specific suffix '652' against official manufacturer documentation to confirm the exact tape-and-reel packaging format and quantity per reel. Ensure the selected variant matches the required operating temperature range and voltage specifications for your target application environment before finalizing procurement orders.

Latches Selection Notes

Select this component when an octal latch with high-impedance states is required for bus-oriented architectures. The inverting nature distinguishes it from non-inverting alternatives like the 74HC573. Confirm that the system voltage falls within the specified 2.0 V to 6.0 V range to ensure proper logic level translation and signal integrity during operation.

Latches Part Context

This part belongs to the 74HC/HCT/HCU/HCMOS logic family, designed for low-power CMOS applications. It serves as a fundamental building block for sequential logic circuits, offering high noise immunity and wide operating voltage flexibility compared to older transistor-transistor logic families.
