CD74FCT2652TQM

Overview

The CD74FCT2652TQM is a high-speed, dual 4-bit to 1-of-16 data selector/multiplexer manufactured by Harris Corporation. It operates within a supply voltage range of 4.75V to 5.25V and features a non-inverting transceiver configuration with three-state outputs. The device is housed in a 24-QSOP surface-mount package containing 24 terminals. Designed for CMOS technology, it supports bidirectional data transmission and includes independent control mechanisms. The component is rated for an operating temperature range from -55°C to 125°C, ensuring reliability in demanding electronic environments.

Feature Summary

• Dual 4-bit to 1-of-16 data selection capability for multiplexed transmission
• Non-inverting transceiver design with three-state output buffering
• Independent control logic for registered and real-time data switching

Applications

• High-performance data switching systems
• Multiplexed transmission of registered or real-time data
• Robust data transmission in electronic systems requiring reliable signal integrity

Procurement Notes

Verify the specific suffix TQM corresponds to the 24-QSOP package variant when sourcing. Confirm RoHS compliance status as historical Harris documentation may indicate non-compliance. Ensure the supplier provides official datasheets matching the CD74FCT2652 series specifications. Check for availability of original manufacturer documentation to validate pinout and electrical characteristics against current inventory.

Selection Notes

Select this component for applications requiring dual 4-to-16 multiplexing functions within FCT logic families. It is suitable where non-inverting signal paths and three-state isolation are necessary. Consider the 24-QSOP footprint for board space constraints. Verify that the 4.75V to 5.25V operating voltage aligns with the system power rails. Ensure thermal management supports the specified wide temperature range.

Part Context

This part belongs to the Harris CD74FCT series, which utilizes Fast CMOS technology for high-speed operation. It shares functional similarities with other FCT multiplexers but is distinct in its dual 4-bit to 1-of-16 architecture. The TQM suffix denotes the specific small-outline quad package type. It is part of a broader family of bus transceivers and selectors designed for complex digital interconnects.
