概述

Description

The 74HC373PW is a high-speed CMOS octal D-type transparent latch with 3-state outputs. It is part of the 74HC series, which is known for its high performance and low power consumption. This device is used for temporary data storage and data buffering in digital circuits. It features eight latches with a common latch enable (LE) and output enable (OE) controls. When LE is high, data at the D inputs is latched to the Q outputs. When LE is low, the last data is retained. The outputs can be set to high-impedance state with the OE pin, allowing for easy interfacing with other bus-oriented systems.
The 74HC373PW operates with a supply voltage range of 2V to 6V, making it suitable for various applications. It is often used in applications requiring temporary data holding, such as memory interfacing, data transfer between systems, and microcontroller I/O expansion. Packaged in a TSSOP-20, it is ideal for high-density circuit designs. Its compatibility with TTL and CMOS logic families enhances its versatility in digital electronics projects.

Pinout

The 74HC373PW is a high-speed CMOS octal D-type transparent latch with 3-state outputs. It features an 8-bit latch function, where the data is stored at the outputs when the latch-enable (LE) input is high. When LE is low, the outputs retain their previous state. The outputs can be set to a high-impedance state by applying a high signal to the output enable (OE) pin, which allows for bus line sharing.
The pin count of the 74HC373PW is 20, which typically includes:
- 8 data inputs (D0 to D7)
- 8 data outputs (Q0 to Q7)
- 1 latch-enable input (LE)
- 1 output enable input (OE)
- 1 ground pin (GND)
- 1 supply voltage pin (VCC)
The specific pin configuration can vary by package type, so it's important to refer to the datasheet for exact pin assignments in your specific application. This IC is widely used in applications requiring temporary data storage and bus interfacing.
