概述

Description

The 74HC373PW is an octal transparent latch designed for use in digital circuits. It consists of eight D-type flip-flops with output control and enables functionality, allowing data to be latched when the enable input is active. This device operates with a supply voltage range of 2V to 6V and is compatible with both TTL and CMOS logic levels.
Key features include:
- Octal data inputs: Eight data inputs (D0-D7) allow parallel data entry.
- Transparent operation: When the enable pin is active, data is continuously passed from inputs to outputs.
- Latch functionality: When the enable pin is deactivated, the current data is latched, holding the output stable.
- Active low output enable: The outputs can be disabled to prevent loading on the bus.
The 74HC373PW is widely used in microcontroller applications, data storage, and transfer tasks, making it essential for effective data management in digital systems. Its high-speed performance and low power consumption make it suitable for modern electronic applications.

Features

The 74HC373PW is an octal transparent latch designed for high-speed applications. Key features include:
1. Octal Latch: Contains eight latches that store data inputs.
2. Transparent Mode: When the latch enable (LE) is high, data input is continually passed to the outputs.
3. Input/Output: Compatible with TTL levels, allowing easy interfacing with other logic families.
4. Control Inputs: Features two control inputs: LE (Latch Enable) and OE (Output Enable) for managing data flow.
5. High-Speed Operation: Operates at fast switching speeds, making it suitable for high-frequency applications.
6. Low Power Consumption: Designed for reduced power usage, making it energy efficient.
7. Wide Supply Voltage Range: Operates across a supply voltage range of 2V to 6V.
8. DIP and Surface Mount Packages: Available in various package types, including PW (TSSOP) for space-constrained designs.
These features make the 74HC373PW ideal for temporary data storage and buffering in digital circuits.

Package

The 74HC373PW is packaged in a TSSOP (Thin Shrink Small Outline Package) which has 20 pins. This surface-mount package is designed for space-saving applications and is commonly used in digital circuits for latching data.

Pinout

The 74HC373PW is an octal transparent latch with a pin count of 20. It features eight data inputs (D0-D7), eight outputs (Q0-Q7), and control inputs. The key pins include:
- Inputs:
- D0-D7: Data inputs for latching.
- LE (Latch Enable): When high, data appears at outputs; when low, the outputs latch the data.
- Outputs:
- Q0-Q7: Latch outputs that reflect the states of the data inputs when enabled.
- Control:
- G (Output Enable): When low, enables outputs; when high, outputs are in a high-impedance state.
- Power:
- VCC: Positive power supply.
- GND: Ground.
The device is used in applications requiring temporary data storage and transfer, such as buffering data in digital circuits.
