概述

Description

The SN74HCT373N is an octal transparent latch designed for use in digital circuits. It features eight D-type latches that allow data to be stored when the latch enable (LE) pin is activated. When LE is high, the latches are transparent, meaning they continuously pass the input data to the output. When LE goes low, the last input data is latched and held at the outputs until LE goes high again.
This device operates on a wide voltage range (2V to 5.5V) and is compatible with both TTL and CMOS logic levels, making it versatile for various applications. It also features active-low output enables, facilitating easy control of output states.
The SN74HCT373N is commonly used in applications requiring temporary data storage and transfer, such as data buffering and temporary data holding in communication systems. It is packaged in a 20-pin DIP format, making it easy to integrate into various circuit designs.

Features

The SN74HCT373N is an octal transparent latch designed for use in digital circuits. Key features include:
1. 8-bit Latch: It can store 8 bits of data, with all latches being transparent when the enable (OE) signal is active.
2. High-Performance TTL Compatible: Designed for high-speed operation, it operates at 5V supply voltage with TTL compatibility.
3. Data Input/Output: Offers 8 data inputs (D0-D7) and 8 outputs (Q0-Q7) for seamless data handling.
4. Control Signals: Features a latch enable (LE) and output enable (OE) for controlling data flow and output states.
5. Low Power Consumption: Consumes low static and dynamic power, enhancing efficiency.
6. Wide Operating Range: Supports a wide range of input voltage levels, accommodating various logic families.
7. Package Type: Available in a 20-pin DIP package, making it easy to integrate into circuit designs.
These features make the SN74HCT373N versatile for applications in data storage and transfer within digital systems.

Package

The SN74HCT373N is packaged in a 20-pin DIP (Dual In-line Package). This type of package allows for easy insertion into PCBs and is suitable for through-hole mounting.

Pinout

The SN74HCT373N is an octal transparent latch with a pin count of 20. It features eight data inputs (D0–D7), eight data outputs (Q0–Q7), an output enable (OE), a latch enable (LE), and a common ground (GND) and supply voltage (VCC) pin.
Pin Functions:
1. D0-D7 (Pins 1-8): Data inputs.
2. OE (Pin 9): Output enable; when low, it enables the outputs.
3. LE (Pin 10): Latch enable; when high, the data present at the inputs is latched onto the outputs.
4. Q0-Q7 (Pins 11-18): Data outputs corresponding to the inputs.
5. GND (Pin 19): Ground connection.
6. VCC (Pin 20): Power supply connection.
This device is designed for use in high-speed applications and operates with TTL-compatible logic levels, making it suitable for various digital systems.
