74ALVCH16841DGGY

Overview

The Nexperia 74ALVCH16841DGGY is a 20-bit bus interface D-type latch featuring two independent 10-bit registers with 3-state outputs. It operates within a supply voltage range of 1.2 V to 3.6 V and supports direct interfacing with TTL levels. The device includes active bus hold circuitry on all data inputs, eliminating the need for external pull-up or pull-down resistors. It utilizes a MULTIBYTE™ flow-through standard pin-out architecture with low inductance multiple VCC and GND pins to minimize noise and ground bounce.

Feature Summary

• Features active bus hold circuitry on all data inputs to maintain valid logic levels without external components
• Provides 3-state non-inverting outputs suitable for bus-oriented applications
• Utilizes low inductance multiple VCC and GND pins to reduce noise and ground bounce
• Supports direct interface with TTL levels across the specified voltage range

Applications

• Bus oriented applications requiring 20-bit data latching
• Mixed voltage environments utilizing direct TTL level interfacing
• Systems requiring active bus hold functionality to manage floating inputs

Procurement Notes

Verify the specific ordering suffix 'Y' against official Nexperia documentation to confirm packaging details such as reel specifications. Confirm current product status, as distributor sources may indicate end-of-life conditions. Ensure compatibility with required temperature ranges and moisture sensitivity levels before procurement.

Selection Notes

Select this component for designs requiring 20-bit parallel data storage with high-impedance output control. The MULTIBYTE™ architecture simplifies PCB layout for wide buses. Verify that the operating voltage falls within the 1.2 V to 3.6 V range and that the TSSOP56 package fits the board space constraints.

Part Context

This part belongs to the 74ALVCH series of advanced low-voltage CMOS logic devices manufactured by Nexperia. It is housed in a TSSOP56 plastic thin shrink small outline package (SOT364-1). The device is designed for operation across an ambient temperature range of -40 °C to +85 °C.

Replacement Considerations

Consult official Nexperia substitution guides for verified alternatives. Generic logic families may not match the specific bus hold features or MULTIBYTE™ pinout architecture.
