CD74FCT162374ETSM

Overview

The CD74FCT162374ETSM is a CMOS bus transceiver from the FCT series, manufactured by Harris Corporation. It features two independent functions, each handling eight bits of data with true output polarity. The device utilizes a PDSO48 package and operates within a temperature range of -40 °C to 85 °C. Outputs are characterized as three-state with series resistors. The component supports bidirectional counting direction and includes bus hold inputs to eliminate the need for external pull-up resistors.

Feature Summary

• Features bus hold inputs that eliminate the requirement for external pull-up resistors
• Provides independent control for dual eight-bit functions
• Supports bidirectional data transfer capabilities

Applications

• High-speed data bus interfacing in digital systems
• Memory bus architectures requiring bidirectional data flow
• Logic level translation between CMOS components

Procurement Notes

Verify the manufacturer designation carefully, as Harris Corporation logic assets were acquired by other entities. Confirm the specific suffix matches the required package and temperature grade. Check RoHS compliance status as original Harris parts may not meet current environmental standards. Ensure the datasheet corresponds to the exact part number variant to confirm pinout and electrical characteristics.

Selection Notes

Select this component when independent dual eight-bit bidirectional buffering is required. The integrated bus hold feature simplifies design by removing external pull-up requirements. Verify that the PDSO48 package fits the board layout constraints. Ensure the operating voltage and temperature ranges align with the system specifications before integration.

Part Context

This component belongs to the Harris FCT (Fast CMOS) logic family, designed for high-speed applications. The FCT series bridges the performance gap between standard TTL and advanced CMOS technologies. Harris Corporation was a primary producer of these logic devices before industry consolidation affected product lines and availability.
