概述

Description

The 74LVC273PW is a high-speed octal latch designed for use in digital circuits. It belongs to the 74LVC family of logic devices and operates with low voltage levels, making it suitable for battery-operated applications. The device features eight data inputs (D0-D7) and eight corresponding outputs (Q0-Q7), with a latch-enable (LE) input that allows data to be stored when activated.
It operates with logic levels from 1.65V to 5.5V, ensuring compatibility with various TTL and CMOS systems. The device also includes an active-low output enable (OE) pin, allowing you to control the output states. The 74LVC273 is known for its fast switching times, low propagation delay, and low power consumption, making it ideal for high-performance applications.
Common use cases include data storage in microcontroller interfaces, temporary data holding in digital systems, and state holding for sequential logic designs. It is available in a 20-pin TSSOP package, facilitating easy integration into compact circuit designs.

Features

The 74LVC273PW is an 8-bit D-type latch with a tri-state output from Texas Instruments. Key features include:
1. Data Storage: It has 8 D-type latches that store data on the rising edge of the clock signal.
2. Tri-State Outputs: Outputs can be enabled or disabled, allowing for effective bus communication.
3. Single Supply Voltage: Operates from a supply voltage range of 1.2V to 3.6V, making it suitable for low-power applications.
4. High-Speed Operation: The device supports high-speed data transfer with a typical propagation delay of 4.5 ns at 3.3V.
5. Low Power Consumption: Designed with CMOS technology, it exhibits low static and dynamic power consumption.
6. Wide Input Voltage Tolerance: Accepts input voltages up to 5.5V, ensuring compatibility with various logic families.
7. Temperature Range: Functional across a temperature range of -40°C to 125°C, suitable for industrial applications.
Overall, the 74LVC273PW offers versatility for data storage and transfer in high-speed digital circuits.

Package

The 74LVC273PW is housed in a TSSOP-20 (Thin Shrink Small Outline Package) package type.

Pinout

The 74LVC273PW is an 8-bit transparent latch with a pin count of 20. It features the following key functions:
1. Data Inputs (D0-D7): 8 data inputs for the latch.
2. Latch Enable (LE): Controls when data is latched; when high, data is passed to the output.
3. Output Enable (OE): Active low control that enables or disables the output.
4. Clock Input (CLK): Used for data latching; data is captured on the rising edge of the clock when LE is low.
5. Outputs (Q0-Q7): 8 outputs corresponding to the data inputs.
The device operates with a wide voltage range and is designed for use in high-speed applications, providing low power consumption and high-speed operation. It is often used in data storage and transfer applications in digital circuits.
