74ALVCH16373DGG,51

Overview

The Nexperia 74ALVCH16373DGG,51 is a 16-bit D-type transparent latch featuring bus hold inputs and three-state outputs. It supports a wide supply voltage range from 1.2 V to 3.6 V and operates within an ambient temperature of -40 °C to +85 °C. The device utilizes a TSSOP48 (SOT362-1) package with 48 leads. Propagation delay ranges from 1.0 ns to 5.9 ns depending on voltage and load conditions. Output drive capability reaches ±24 mA at 3.0 V, enabling direct interface with TTL levels.

Feature Summary

• Features MULTIBYTE flow-through standard pin-out architecture for efficient data handling
• Includes bus hold circuitry on all data inputs to maintain stable logic states
• Supports partial power-down applications via integrated IOFF circuitry
• Provides low inductance multiple VCC and GND pins to minimize noise

Applications

• Parallel data storage in high-speed digital systems
• Bus holding for memory address latching
• Interface bridging between different voltage domains

Procurement Notes

Verify the specific ordering suffix matches the required tape and reel configuration. Confirm that the package variant corresponds exactly to SOT362-1. Ensure the temperature grade aligns with system requirements for industrial or commercial environments. Cross-reference the manufacturer part number against official Nexperia databases to validate authenticity before procurement.

Selection Notes

Select this component when a 16-bit latch with three-state outputs and bus hold functionality is required. It is suitable for designs needing direct TTL interfacing and operation across a broad voltage spectrum. Consider the TSSOP48 package constraints and thermal dissipation limits during layout. Verify that the propagation delay specifications meet the timing requirements of the target application.

Part Context

This component belongs to the 74ALVCH series of advanced low-voltage CMOS logic devices. It is designed for applications requiring high speed and low power consumption. The device integrates features typical of modern bus transceivers and latches, focusing on signal integrity and noise immunity in dense PCB layouts.

Replacement Considerations

Check for compatible parts within the same 74ALVCH family that share identical pinouts and electrical characteristics. Ensure any substitute maintains the bus hold feature and three-state output capability. Verify package compatibility and operating temperature ranges match the original specification.
