74ALVCH16373DGG:11

Overview

The Nexperia 74ALVCH16373DGG:11 is a 16-bit D-type transparent latch with bus hold inputs and 3-state outputs, housed in a TSSOP48 (SOT362-1) package. It operates within a supply voltage range of 1.2 V to 3.6 V and supports an ambient temperature range of -40 °C to +85 °C. The device features two independent 8-bit latches controlled by separate latch enables (1LE, 2LE) and output enables (1OE, 2OE). Propagation delay from data input to output ranges from 1.0 ns to 5.7 ns depending on voltage and load conditions.

Feature Summary

• Bus hold inputs maintain stable logic states without external pull-up or pull-down resistors
• IOFF circuitry prevents damaging backflow current during partial power-down scenarios
• MULTIBYTE flow-through architecture ensures standard pin-out compatibility for high-density designs

Applications

• Parallel data storage in digital communication systems
• Buffering and register applications in embedded controllers
• Interface bridging between microprocessors and peripheral devices

Procurement Notes

Verify the specific ordering suffix :11 corresponds to the required tape and reel packaging configuration. Confirm that the TSSOP48 variant matches your PCB footprint requirements. Ensure design compliance with the specified -40 °C to +85 °C operating temperature range for your intended environment.

Selection Notes

Select this component when a wide supply voltage range from 1.2 V to 3.6 V is required for mixed-voltage system integration. The inclusion of bus hold inputs simplifies board layout by eliminating external termination components. Verify that the 3-state output capability meets the bidirectional bus requirements of your target application architecture.

Part Context

This part belongs to the Nexperia 74ALVCH series of advanced low-voltage CMOS logic devices. It provides high-speed performance suitable for modern digital interfaces while maintaining low power consumption. The device is manufactured using Nexperia's standard CMOS process technology optimized for reliability and noise immunity.

Replacement Considerations

Direct functional equivalents may include other 16-bit transparent latches with 3-state outputs and bus hold features from compatible logic families. Verify pinout compatibility and electrical specifications before substitution.
