74VCX16374MTDX

Overview

The Fairchild Semiconductor 74VCX16374MTDX is a low voltage, 16-bit D-type flip-flop with 3-state outputs. It features dual supply rails: VCCA (2.3V to 3.6V) and VCCB (1.65V to 2.7V). The device provides true signal translation between busses at different supply voltages, supporting bidirectional interfaces ranging from 1.65V to 3.6V. It utilizes patented Quiet Series noise reduction circuitry and supports live insertion and withdrawal.

Feature Summary

• Dual supply design enabling signal translation between 1.8V to 2.5V busses and higher potential busses up to 3.3V
• Patented Quiet Series technology for noise and EMI reduction
• Supports live insertion and withdrawal operations
• High static drive capability with latchup protection exceeding 300 mA

Applications

• Bidirectional interface between busses operating at different supply voltages
• Two-way asynchronous communication systems
• Bus-oriented applications requiring signal level translation

Procurement Notes

Verify the specific manufacturer source, as ON Semiconductor also produces this part number following industry consolidation. Confirm package type and suffix accuracy against official datasheets. Ensure environmental compliance status matches project requirements. Cross-reference pinouts if substituting from other logic families.

Selection Notes

Select this component when translating signals between 1.65V and 3.6V domains is required. It is suitable for applications needing high-speed data latching with 3-state output control. Consider its dual-supply architecture for mixed-voltage system designs. Evaluate ESD performance and noise immunity requirements before implementation.

Part Context

This part belongs to the VCX series of low voltage translating transceivers and latches. It is functionally compatible with standard 74-series devices but optimized for lower voltage operation. The MTDX suffix indicates a specific tape-and-reel packaging format suitable for automated assembly processes in high-volume manufacturing environments.

Replacement Considerations

The 74VCX16374MTD is a similar variant without the X suffix. Verify functional compatibility and package dimensions before substitution. Check if alternative manufacturers offer equivalent dual-supply translating latch solutions.
