74HC652D,118

Overview

The 74HC652D,118 is an octal bus transceiver and register manufactured by NXP USA Inc. It features three-state outputs and operates within a supply voltage range of 2V to 6V. The device is housed in a 24-SO package. This component is part of the 74HC series, designed for high-speed SI-gate CMOS applications. It is pin-compatible with Low Power Schottky TTL (LSTTL). The specific part number 74HC652D,118 is currently obsolete and no longer manufactured.

Feature Summary

• Octal bus transceiver functionality with register capability
• Three-state output configuration for bus line isolation
• High-speed SI-gate CMOS technology
• Pin-compatible with Low Power Schottky TTL standards

Applications

• Data bus buffering and registration
• Memory interface circuits
• I/O port expansion systems

Procurement Notes

This component is officially classified as obsolete by the manufacturer. No new production units are available from NXP USA Inc. or authorized distributors. Procurement efforts should focus on verifying the authenticity of existing stock from secondary market sources. Buyers must confirm the manufacturing date code and physical condition prior to acquisition. Integration into new designs is not recommended due to end-of-life status.

Selection Notes

Designers requiring this functionality should evaluate current generation equivalents within the 74HC family. Verify that replacement parts maintain compatibility with existing LSTTL interfaces if required. Ensure the selected substitute supports the necessary voltage range and package dimensions. Review updated datasheets for any changes in electrical characteristics or pin assignments compared to the legacy 74HC652 specification.

Part Context

The 74HC652 belongs to the widely used 74HC logic family, known for broad adoption in digital electronics. The 'D' suffix indicates a SOIC-style package, while ',118' denotes specific tape-and-reel packaging details. As an octal transceiver, it facilitates data transfer between buses and registers. Its obsolescence reflects standard product lifecycle management practices common in semiconductor manufacturing.
