74HCT652D,112

Overview

The 74HCT652D,112 is an obsolete registered bus transceiver from NXP Semiconductors. It belongs to the HCT logic family and features a non-inverting configuration with one element of eight bits per element. The device provides three-state outputs and utilizes a 24-pin SO package for surface mount installation. It operates within a supply voltage range of 4.5 V to 5.5 V and supports a maximum operating temperature of +125 °C.

Feature Summary

• Registered bus transceiver functionality with non-inverting signal path
• Three-state output capability for bus line isolation
• CMOS construction compatible with standard TTL levels

Applications

• High-speed data transmission systems
• Bus-oriented memory interfacing
• Control signal routing in industrial equipment

Procurement Notes

This component is officially marked as obsolete by NXP USA Inc. and is no longer manufactured. Procurement should focus on verified surplus stock or authorized distributors holding remaining inventory. Verify part authenticity carefully due to the discontinued status. Ensure the specific suffix matches the required package type before ordering.

Selection Notes

Select this component only if legacy system compatibility requires the exact 74HCT652 specification. Consider the SN74HCT652DW as a potential substitute if pin-compatible alternatives are available. Evaluate current availability constraints and long-term supply chain risks associated with obsolete logic families before finalizing design choices.

Part Context

The 74HCT652D,112 is part of the broader 74HCT series of high-speed CMOS logic devices. It serves as a registered transceiver, combining buffering and latching functions in a single package. This specific variant is designed for applications requiring reliable data transfer across multiple lines with synchronized timing control.

Replacement Considerations

Public confirmed substitute: SN74HCT652DW.
