74ALVCH16374DGG112

Overview

The 74ALVCH16374DGG,112 is a 16-bit edge-triggered D-type flip-flop manufactured by Nexperia (formerly NXP Semiconductors logic division). 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 to eliminate the need for external pull-up or pull-down resistors for 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 TSSOP-48 package.

Feature Summary

• Provides 16-bit edge-triggered D-type flip-flop functionality with 3-state outputs for bus-oriented applications
• Incorporates bus hold data inputs to maintain input states without external resistors
• Supports direct interface with TTL levels and drives 50 ohm transmission lines at 85 degrees Celsius

Applications

• Bus-oriented digital systems requiring 16-bit data storage
• Mixed voltage environments utilizing 1.2 V to 3.6 V supply rails
• Applications requiring elimination of external pull-up or pull-down resistors for unused inputs

Procurement Notes

Verify current availability status as this component may be subject to end-of-life restrictions. Confirm that the manufacturer designation aligns with current Nexoria product portfolios rather than legacy NXP branding. Ensure the TSSOP-48 package variant matches design requirements. Validate RoHS compliance documentation prior to integration into production schedules.

Selection Notes

Select this component when designing systems requiring 16-bit parallel data latching with tri-state output control. The bus hold feature simplifies PCB layout by removing passive components for floating inputs. Ensure the operating voltage falls within the 1.2 V to 3.6 V range. Consider the TSSOP-48 footprint constraints during mechanical design phase.

Part Context

This part belongs to the 74ALVCH series of high-speed CMOS logic devices. It is functionally similar to other 16-bit flip-flops in the ALVCH family but specific to the D-type configuration with 3-state outputs. The '112' suffix typically denotes tape and reel packaging or specific manufacturing lot codes depending on the distributor catalog structure.

Replacement Considerations

The 74ALVCH16374DL is a documented equivalent part number from NXP Semiconductors offering identical logical functionality. Verify pinout compatibility and package dimensions before substitution. Check if the replacement part meets the same JEDEC standards and electrical specifications.
