Product Overview: 74HC373PW by NXP

The 74HC373PW is a high-speed Si-gate CMOS device that is part of NXP Semiconductors' extensive 74HC (High-Speed CMOS) logic family. This particular integrated circuit is designed to offer the functionality of octal D-type transparent latches with 3-state outputs. It is a versatile component that is suitable for a wide range of applications in digital systems where temporary storage of data is required.

Key Features

• Octal D-type Latches: The device contains eight latches with 3-state outputs, allowing for the storage of eight bits of data.
• Transparent Latches: Data on the D-input is transferred to the latch output when the latch-enable (LE) input is high and is retained when LE is low.
• 3-State Outputs: The 74HC373PW features 3-state outputs which can be set to high impedance. This is essential for interfacing with bus-oriented systems as it allows multiple outputs to be connected to a bus without causing conflicts.
• Wide Operating Voltage Range: It operates across a voltage range of 2.0 to 6.0 V, making it compatible with TTL levels and suitable for use in systems with different power requirements.
• High Noise Immunity: The CMOS technology provides a high noise immunity level, ensuring stable operation in electrically noisy environments.
• Low Power Consumption: The device has a low power consumption characteristic of CMOS integrated circuits, making it ideal for battery-operated devices.

Package and Quality

The 74HC373PW is housed in a TSSOP20 (Thin Shrink Small Outline Package) which is not only space-efficient but also suitable for surface mount technology (SMT). The package is designed to optimize the PCB space and improve the overall reliability of the application.

Applications

Thanks to its robust design and latch functionality, the 74HC373PW is applicable in various fields, including:

• Computer systems
• Data storage and retrieval
• Communication systems
• Industrial control systems
• Instrumentation

With its combination of high-speed operation, latch capabilities, and 3-state outputs, the NXP 74HC373PW is a valuable component for designers who require reliable temporary data storage in their digital logic applications.
