74ALVCH16843DGGS

Overview

The Nexperia 74ALVCH16843DGGS 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, active bus hold circuitry for floating inputs, and complies with JEDEC standards JESD8-5 and JESD8B/JESD36.

Feature Summary

• Features active bus hold circuitry to maintain valid logic levels on unused or floating data inputs without external resistors.
• Provides 3-State non-inverting outputs suitable for bus-oriented applications with high impedance OFF states.
• Includes low inductance multiple VCC and GND pins designed to minimize noise and ground bounce effects.

Applications

• Bus-oriented data storage applications
• High-speed interface circuits requiring transparent latching
• Systems utilizing MULTIBYTE flow-through standard pin-out architecture

Procurement Notes

Verify the specific suffix 'GS' against official Nexperia documentation, as the primary datasheet references the 'DGG' package variant. Confirm availability status directly with the manufacturer or authorized distributors, as component lifecycle stages may affect procurement options.

Selection Notes

Select this component for designs requiring 18-bit parallel data latching with tri-state control. Ensure the operating environment stays within the specified -40 °C to +85 °C temperature range and that supply voltages align with the recommended 2.3 V to 3.6 V limits for optimal performance.
