Product Overview: 74ALVCH16374DL from NXP

The 74ALVCH16374DL is a high-performance, low-voltage 16-bit D-type flip-flop with 3-state outputs from NXP Semiconductors. Designed with advanced CMOS technology, this integrated circuit (IC) is part of the ALVCH family, which is well-suited for low-voltage operation while providing robust high-speed performance.

This device features two sections of eight flip-flops with individual D-type inputs and 3-state outputs. The flip-flops are edge-triggered, capturing the value of their D-inputs on the rising edge of the clock signal, CLK. The 3-state outputs ensure that multiple outputs can be connected to a common bus without conflict, providing a high degree of flexibility in bus-oriented systems.

Key Features:

• Wide Operating Voltage Range: The 74ALVCH16374DL operates at a nominal voltage of 3.3V, which is ideal for interfacing with modern low-voltage microprocessors and digital systems.
• High-Speed Operation: This IC is capable of toggling at very high speeds, making it suitable for high-frequency data storage and transfer applications.
• Bus-Hold Feature: The inputs have a bus-hold feature, which eliminates the need for external pull-up or pull-down resistors and helps to maintain the last known state when inputs are left floating.
• Power-Down Protection: Inputs and outputs are equipped with power-down protection, which ensures that no excess current is drawn if the device is powered down.
• Low Power Dissipation: The IC has been optimized for low power consumption, contributing to energy-efficient designs.
• Output Drive Capability: The outputs can drive up to 24 mA, providing good signal integrity when driving loads.
• Pin Compatibility: The device is pin-compatible with other standard logic families, making it easy to integrate into existing designs without significant rework.

Applications:

The 74ALVCH16374DL is versatile and can be used in a wide range of applications, including:

• Memory address latching
• Data storage and transfer in computer and embedded systems
• Interfacing and bus driving in multi-voltage systems
• Communications infrastructure
• Industrial control systems

Its robust performance characteristics and low-voltage operation make the 74ALVCH16374DL an excellent choice for designers seeking to create compact, efficient, and high-speed digital circuits.
