概述

Description

The SN74LV373ADW is a high-speed, low-voltage octal transparent latch designed for use in digital circuits. It features eight latches that are controlled by a common latch enable (LE) signal, allowing data to be captured and held when LE is low. When LE is high, the latches are transparent, meaning they continuously pass input data to output. The device operates within a voltage range of 2.7V to 3.6V, making it suitable for low-power applications.
Key features include a fast propagation delay (typically around 5 ns at 3.3V) and low power consumption, which make it ideal for use in battery-operated devices. The SN74LV373ADW is compatible with standard TTL and CMOS logic levels, ensuring integration with various digital systems. It is available in a wide range of package options, including SOIC and TSSOP, facilitating easy incorporation into PCB designs. Overall, this latch is widely used in data storage, buffering, and timing applications in modern electronic devices.

Features

The SN74LV373ADW is an octal transparent latch designed for high-speed data processing and storage. Key features include:
1. Data Latching: It has 8 bits of data input that can be latched when the latch enable (LE) signal is activated.
2. Wide Supply Voltage: Operates with a power supply range of 2V to 5.5V, making it suitable for various logic levels.
3. Low Power Consumption: Designed for low power usage, enhancing battery-operated device efficiency.
4. High-Speed Operation: Capable of high-speed performance, with propagation delays typically under 15 ns.
5. 3-State Outputs: Outputs can be in a high-impedance state, allowing for easy bus interfacing.
6. TTL Compatible: Compatible with TTL levels, ensuring integration with legacy systems.
7. Temperature Range: Designed to operate in industrial temperature ranges, ensuring reliability in various environments.
This makes the SN74LV373ADW ideal for applications in data buffering, storage, and multiplexing in digital circuits.

Package

The SN74LV373ADW is packaged in a TSSOP (Thin Shrink Small Outline Package) with 20 pins.

Pinout

The SN74LV373ADW is a quad D latch with an active-low enable input. It features a total of 20 pins. The primary functions of its pins are as follows:
1. Data Inputs (D0 - D3): Pins 1-4 for data input.
2. Latch Enable (LE): Pin 5, active low, enables the latching of data when asserted.
3. Output Enable (OE): Pin 6, active low, controls the output state.
4. Data Outputs (Q0 - Q3): Pins 7-10 for the latched output.
5. Ground (GND): Pin 11, connects to the ground.
6. VCC: Pin 20, connects to the positive supply voltage.
7. Additional Pins: Pins 12-19 are used for supporting logic functions and output.
The device is designed for operation with a supply voltage range of 2.7V to 3.6V, making it suitable for low-voltage applications.
