Overview
The 74VCXH16374DT is a high-speed, low-voltage D-type flip-flop manufactured by onsemi. It features two independent eight-bit registers with positive-edge triggered clock inputs and three-state outputs. Designed for 1.2V to 3.6V VCC applications, it offers I/O compatibility up to 3.6V. The device utilizes advanced CMOS technology to achieve propagation delays of 3ns at 3.3V with 30pF load. It operates within a temperature range of -40°C to 85°C and is available in a 48-TFSOP package.
Feature Summary
- High-speed data storage with positive-edge triggering
- Low voltage operation from 1.2V to 3.6V
- Three-state outputs for bus driving
- I/O compatibility up to 3.6V
Applications
- Parallel data storage
- Bus driver applications
- Memory interface circuits
- Digital signal processing systems
Procurement Notes
Verify the exact part number suffix against official datasheets, as variations like 'MTDX' or 'DT' may indicate different packaging or status. Confirm availability status, as some variants are marked as obsolete. Ensure the supplier provides valid traceability documentation. Cross-reference the manufacturer product number with the distributor listing to avoid counterfeit components. Check for RoHS compliance if required by your design specifications.
Selection Notes
Select this component when designing low-voltage digital systems requiring high-speed parallel data latching. The 74VCX series is suitable for applications needing I/O compatibility with 3.6V logic levels while operating at lower core voltages. Consider the 48-TFSOP package size for space-constrained PCB layouts. Evaluate the 3ns propagation delay against system timing requirements. Ensure the power supply range aligns with the 1.2V to 3.6V specification.
Part Context
This component belongs to the 74VCX family of high-speed CMOS logic devices. The 74VCX series is designed for low-power, high-speed applications in portable and battery-operated devices. It offers performance comparable to older ALVC families but with improved power efficiency. The 74VCXH16374 variant specifically targets bus driver and register applications requiring wide data paths.
Replacement Considerations
Check for direct pin-compatible alternatives within the 74VCX family. Verify if the 'DT' suffix indicates a specific tape-and-reel option versus bulk packaging. Consult onsemi's official replacement guide for end-of-life notifications. Ensure any substitute maintains the same voltage range and output drive capability.
