74ALVCH16843DGG,11

Overview

The Nexperia 74ALVCH16843DGG,11 is an 18-bit bus-interface D-type latch featuring two independent 9-bit registers with 3-state outputs. It operates within a supply voltage range of 2.3 V to 3.6 V and supports propagation delays as low as 1.0 ns. The device provides ±24 mA current drive capability and includes active bus hold circuitry to maintain valid logic levels on floating inputs without external resistors.

Feature Summary

• Features MULTIBYTE flow-through architecture for standard pin-out compatibility
• Includes active bus hold circuitry to eliminate external pull-up or pull-down requirements
• Provides low inductance multiple power and ground pins to minimize noise and ground bounce

Applications

• Bus-oriented applications requiring transparent latching
• Mixed 3.3 V and 5 V system interfacing
• Data storage in high-speed digital circuits

Procurement Notes

Verify component authenticity through authorized distributors. Confirm the specific ordering suffix matches the required package variant. Check the latest product status documentation for obsolescence notices or lifecycle changes before finalizing design-in decisions.

Selection Notes

Select this component for designs requiring 18-bit parallel data storage with tri-state bus control. Ensure the operating voltage aligns with the 2.3 V to 3.6 V specification. Verify that the TSSOP56 package dimensions fit the target PCB layout constraints.

Part Context

This part belongs to the 74ALVCH series of advanced low-voltage CMOS logic devices. It is manufactured by Nexperia USA Inc. and utilizes a 56-lead TSSOP plastic thin shrink small outline package (SOT364-1) suitable for surface mount assembly.

Replacement Considerations

The 74ALVCH16843DGGY is listed as a direct substitute for the discontinued 74ALVCH16843DGG,11.
