CD74FCT162245ATSM

Overview

The CD74FCT162245ATSM is a Fast CMOS 16-bit bidirectional bus transceiver manufactured by Harris Corporation. It operates within the FCT series and features two functional blocks, each handling 8 bits of data. The device utilizes a 48-pin SSOP package with a plastic/epoxy body. It supports a supply voltage range typical for 5V logic applications and functions across an extended commercial temperature range from -40°C to +85°C. The component provides true output polarity and includes direction control capabilities inherent to its transceiver architecture.

Feature Summary

• Provides high-speed, low-power CMOS performance as a replacement for older ABT function equivalents
• Features balanced output drivers designed to reduce system switching noise
• Includes power-off disable functionality to permit live insertion without electrical interference

Applications

• High-speed data bus architectures requiring bidirectional transfer
• Memory mapping systems utilizing 16-bit wide data paths
• General-purpose digital logic interfaces in industrial environments

Procurement Notes

Verify the manufacturer origin carefully, as Harris Corporation's semiconductor assets were acquired by Intersil and subsequently by Renesas Electronics. Ensure the specific suffix ATSM matches the required 48-pin SSOP package dimensions and pinout configuration. Confirm lead-free status requirements against the original datasheet specifications, as compliance codes may vary between production eras.

Selection Notes

Select this component when a 16-bit bidirectional interface is required with balanced drive strengths to minimize electromagnetic interference. The balanced driver characteristic distinguishes it from high-drive variants like the standard 16245. Ensure the application environment stays within the specified -40°C to +85°C operating temperature range for reliable operation.

Part Context

This part belongs to the Harris FCT (Fast CMOS Technology) family, which was engineered to offer speed comparable to Schottky TTL while maintaining CMOS power efficiency. The 162245 variant specifically addresses noise-sensitive applications through its balanced output current characteristics, differing from the asymmetric drive found in standard non-balanced transceivers.
