74HC640D,652

Overview

The NXP 74HC640D,652 is an octal bus transceiver featuring inverting three-state outputs. It operates within a supply voltage range of 2 V to 6 V and supports bidirectional data transfer. The device utilizes a 20-pin Small Outline Package (SOP) for surface-mount installation. It functions as a high-speed silicon-gate CMOS component compatible with low-power Schottky TTL logic levels.

Feature Summary

Octal bidirectional bus interface capability
Inverting three-state output configuration
Bus driver output capability

Applications

Bidirectional bus interfacing
Data transmission between buses
Memory mapping applications

Procurement Notes

Verify the specific suffix 652 against official NXP documentation to confirm package dimensions and tape-and-reel specifications. Ensure compatibility with existing SOP-20 footprints on the target PCB layout before finalizing procurement decisions.

Selection Notes

Select this component when an octal transceiver with inverted outputs and three-state control is required. It serves as a direct replacement for similar LSTTL-compatible devices in systems needing bidirectional data flow management across multiple lines simultaneously.

Part Context

This part belongs to the 74HC series of high-speed CMOS logic devices manufactured by NXP Semiconductors. The series is designed to be pin-compatible with low-power Schottky TTL standards, ensuring broad interoperability in mixed-technology digital circuits.
