74ALVCH16374DL,118

Overview

The Nexperia 74ALVCH16374DL,118 is a 16-bit edge-triggered D-type flip-flop featuring 3-state outputs designed for bus-oriented applications. It incorporates bus hold data inputs to eliminate the need for external pull-up or pull-down resistors on unused lines. The device operates within a wide supply voltage range of 1.2 V to 3.6 V and complies with JEDEC standard JESD8-B. It provides an output drive capability suitable for driving 50-ohm transmission lines at 85°C, with a current drive of ±24 mA at VCC = 3.0 V.

Feature Summary

• Features separate D-type inputs for each flip-flop and 3-state outputs optimized for bus-oriented applications.
• Incorporates bus hold data inputs which eliminate the need for external pull-up or pull-down resistors to hold unused inputs.
• Provides low inductance multiple VCC and GND pins for minimum noise and ground bounce.

Applications

• Bus-oriented memory and I/O systems
• Clock buffering and register designs
• High-speed data acquisition systems

Procurement Notes

Verify the specific suffix '118' against the manufacturer's official documentation to confirm tape-and-reel packaging specifications. Confirm that the component meets the required JEDEC standards and temperature ratings for your specific application environment before finalizing procurement.

Selection Notes

Select this component when designing 16-bit wide data paths requiring high-speed edge-triggered storage with tri-state control. The integrated bus hold feature simplifies PCB layout by removing external components for unused lines. Ensure the system voltage aligns with the 1.2 V to 3.6 V operating range.

Part Context

This part belongs to the ALVCH family of advanced low-voltage CMOS logic devices. It is functionally similar to other 16-bit flip-flops but specifically includes bus hold inputs for enhanced stability on floating lines. It serves as a key building block for complex digital interfaces requiring reliable data latching and high-impedance states.

Replacement Considerations

The Texas Instruments SN74ALVCH16374DLG4 is a confirmed substitute offering identical 16-bit edge-triggered functionality with 3-state outputs. Verify pin compatibility and electrical characteristics match your design requirements before substitution.
