CD74FCT162245ATSM96

Overview

The CD74FCT162245ATSM96 is a registered bus transceiver from the FCT series, manufactured by Harris Corporation. It features two functional units, each handling eight bits of data with true output polarity. The device utilizes CMOS technology and is housed in a PDSO56 small outline package. Key electrical parameters include a propagation delay of 6.3 ns, an operating temperature range from -40 °C to 85 °C, and a supply voltage range of 4.5 V to 5.5 V with a nominal rating of 5 V. Outputs are three-state with series resistors, and bus hold inputs eliminate the need for external pull-up resistors.

Feature Summary

• Integrated bus hold inputs that remove the requirement for external pull-up resistors
• Direction control capability for managing data flow between ports
• Three-state outputs equipped with series resistors for signal integrity

Applications

• High-speed data bus interfaces requiring registered buffering
• Memory mapping systems utilizing 8-bit wide data paths
• Industrial control systems operating within extended temperature ranges

Procurement Notes

Verify the manufacturer origin as Harris Corporation, noting that corporate assets were acquired by Texas Instruments. Confirm the specific suffix ATSM96 corresponds to the required tape and reel packaging format. Ensure the component meets the specified FCT logic family standards for voltage and speed compatibility with existing system designs before finalizing procurement orders.

Selection Notes

Select this component when an 8-bit registered transceiver with direction control is required for high-speed applications. The FCT series offers faster switching speeds compared to standard HC or HCT logic families. The PDSO56 package provides a compact solution for dense PCB layouts while maintaining thermal performance suitable for industrial environments.

Part Context

This part belongs to the Harris FCT (Fast CMOS Technology) logic family, designed for high-performance digital applications. The FCT series bridges the gap between older TTL-compatible logic and modern high-speed CMOS technologies, offering improved noise immunity and lower power consumption while maintaining compatible input/output characteristics with legacy systems.
