概述

Description

The SN74HC373N is an octal transparent latch designed for high-speed operations in digital applications. It features eight data inputs (A0 to A7) and eight corresponding outputs (Y0 to Y7). The latch is controlled by an enable input (G), which allows data to pass through when activated. When G is low, the output retains the last input state, making it useful for temporary data storage.
This device operates in the high-speed CMOS logic family, with a supply voltage range of 2V to 6V, providing compatibility with TTL levels. It is ideal for applications requiring temporary holding of data, like bus-oriented systems and data transfer between devices.
The SN74HC373N can operate at high frequencies, making it suitable for fast data processing applications. The package is typically available in DIP or surface-mount configurations, making it versatile for various circuit designs. Overall, it is a reliable component for buffering, latching, and data management in digital systems.

Features

The SN74HC373N is an octal transparent latch with 3-state outputs, designed for high-speed applications. Key features include:
1. Data Latches: Contains eight latches that can store data when the latch-enable (LE) input is high.
2. 3-State Outputs: The outputs can be set to high, low, or high-impedance state for flexible data management.
3. High-Speed Operation: Capable of operating at high frequencies, making it suitable for fast data processing.
4. Wide Supply Voltage Range: Operates with a supply voltage from 2V to 6V, accommodating various applications.
5. TTL-Compatible Inputs: Compatible with TTL logic levels, ensuring integration with other digital components.
6. Low Power Consumption: Designed for low power usage, enhancing efficiency in portable devices.
7. Temperature Range: Functional over a broad temperature range, suitable for industrial applications.
This device is commonly used in data buffering, temporary storage, and state preservation in digital circuits.

Package

The SN74HC373N is typically available in a 20-pin dual in-line package (DIP). This package type features through-hole mounting and is commonly used for easy integration into breadboards and circuit boards.

Pinout

The SN74HC373N is a high-speed CMOS octal transparent latch with 3-state outputs. It has a pin count of 20.
Pin Functions:
1. 1-8 (D0-D7): Data inputs for the eight latches.
2. 9 (LE): Latch Enable input; when HIGH, data present at inputs D0-D7 is transferred to the outputs.
3. 10 (GND): Ground connection.
4. 11 (Q0-Q7): 3-state outputs corresponding to the input data.
5. 12 (OE): Output Enable; when LOW, outputs are enabled; when HIGH, outputs are in a high-impedance state.
6. 13 (Vcc): Power supply connection.
7. 14-20: No internal connections (NC) or additional ground and power connections depending on packaging.
The device is commonly used in applications requiring temporary storage of data, such as in data bus interfaces.
