CD74FCT16646CTSM

Overview

The CD74FCT16646CTSM is a non-inverting logic transceiver manufactured by Harris Corporation. It integrates two independent elements, each handling eight bits of data, for a total of sixteen-bit bidirectional transfer capability. The device utilizes CMOS technology and operates with a supply voltage up to 5.5V. It features three-state outputs to facilitate bus-oriented connections. The component is housed in a 56-pin Small Outline Shrink Package (SSOP) with a pitch of 0.295 inches.

Feature Summary

• Non-inverting logic transceiver design
• Dual independent eight-bit elements
• Three-state output configuration
• CMOS technology construction

Applications

• Bus-oriented memory systems
• Control signal transmission
• Data acquisition systems

Procurement Notes

Verify the manufacturer status as Harris Corporation may have undergone corporate restructuring or acquisition. Confirm the specific package variant matches the 56-SSOP requirement. Check RoHS compliance documentation as indicated by non-compliant status in some records. Ensure the part number suffix aligns with the required tape and reel or tube packaging specifications for your assembly process.

Selection Notes

Select this component when a non-inverting transceiver with dual eight-bit channels is required. The three-state outputs allow for efficient bus sharing without external pull-up resistors. Consider the 56-pin SSOP package constraints for PCB layout. Verify that the operating voltage range supports the system's power supply rails before integration into the design.
