74ABT16500CSSCX

Overview

The 74ABT16500CSSCX is an 18-bit registered bus transceiver from the ABT series, manufactured by Fairchild Semiconductor (now onsemi). It features true outputs and operates in a BICMOS process. The device is housed in a 56-pin SSOP package (PDSO56) and includes 3-state outputs for effective bus driving. As a universal bus function component, it supports bidirectional data transfer with registration capabilities, designed for high-speed digital applications requiring reliable signal integrity and low power consumption.

Feature Summary

• 18-bit registered bus transceiver architecture
• True output configuration with 3-state capability
• BICMOS technology implementation
• Universal bus function support

Applications

• Air conditioner control systems
• Home theater equipment interfaces
• Electric grinding wheel controllers
• Electrical tool management circuits
• Sewing machine logic boards

Procurement Notes

Verify manufacturer lineage as Fairchild Semiconductor assets were acquired by onsemi. Confirm package type matches PDSO56/56-SSOP specifications. Ensure RoHS compliance status aligns with current production batches. Cross-reference datasheet revisions to confirm pinout and electrical characteristics remain consistent with original Fairchild documentation.

Selection Notes

Select this component for applications requiring 18-bit wide data paths with registered storage. The ABT series offers balanced speed and power performance suitable for general-purpose bus interfacing. Verify voltage compatibility with system logic levels. Consider thermal dissipation requirements associated with the SSOP package in dense PCB layouts.

Part Context

This part belongs to the 74ABT16500 series of universal bus transceivers. It shares functional similarities with other 18-bit devices but is distinct in its specific packaging and electrical parameters defined by the ABT family standards. The CSSCX suffix indicates specific tape-and-reel or tube packaging variations within the commercial grade lineup.

Replacement Considerations

Direct substitutes may include other 18-bit registered bus transceivers from compatible logic families. Verify pin-to-pin compatibility before substitution. Check if alternative manufacturers offer equivalent BICMOS technology with matching output drive strengths and propagation delays.
