Overview
The 74ALVCH16374DGG:51 is a 16-bit edge-triggered D-type flip-flop manufactured by NXP Semiconductors. It features separate D-type inputs for each flip-flop and 3-state outputs suitable for bus-oriented applications. The device incorporates bus hold data inputs, eliminating the need for external pull-up or pull-down resistors to maintain unused inputs. It operates within a wide supply voltage range from 1.2 V to 3.6 V and complies with JEDEC standard JESD8-B. The component utilizes a MULTIBYTE flow-through standard pin-out architecture.
Feature Summary
- Features 3-state outputs designed for bus-oriented applications
- Incorporates bus hold data inputs to eliminate external pull-up or pull-down requirements
- Supports direct interface with TTL levels
Applications
- Bus-oriented digital systems requiring 16-bit storage
- High-speed data acquisition systems
- Memory buffer applications in consumer electronics
Procurement Notes
Verify the specific ordering suffix ':51' against official NXP documentation to confirm tape and reel packaging specifications. Confirm current lifecycle status as this series may be subject to discontinuation notices. Ensure compatibility with existing PCB footprints and signal integrity requirements before procurement.
Selection Notes
Select this component for applications requiring 16-bit parallel data storage with high-speed performance. The wide supply voltage range supports various logic families. Consider the MULTIBYTE architecture for simplified board layout compared to discrete solutions. Verify input drive capabilities match the source logic family.
Part Context
This part belongs to the 74ALVCH (Advanced Low-Voltage CMOS High-performance) logic family. It is functionally similar to other 16-bit D-type flip-flops like the 74ALVCH16374DL. The device is designed for low power consumption while maintaining high speed, making it suitable for battery-powered and high-density digital designs.
Replacement Considerations
The 74ALVCH16374DLG4 from Texas Instruments is a documented functional equivalent. Verify pinout compatibility and electrical parameters before substitution.
