概述

Description

The CD74HC238PWR is a high-speed CMOS decoder/demultiplexer, designed for digital applications. It features three binary select inputs, which allow it to decode binary values into one of eight outputs (Y0 to Y7). When a valid enable signal is applied, the selected output is activated (low), while the others remain high.
Key attributes include:
- Logic Family: Part of the 74HC series, known for high-speed and low-power operation.
- Operating Voltage: Typically operates between 2V to 6V.
- Propagation Delay: Fast switching times, usually around 8 ns at 5V.
- Functionality: It can also be used as a demultiplexer or for address decoding in memory applications.
- Pin Configuration: Available in various packages, including SOIC and TSSOP.
Applications include data routing, memory selection, and other logic functions in digital circuitry. The CD74HC238PWR offers a compact solution for efficient digital design with reliable performance.

Features

The CD74HC238PWR is a high-speed CMOS 3-to-8 line decoder/demultiplexer, featuring:
1. 3 Address Inputs: It can decode 3 binary inputs into 8 unique outputs.
2. Active LOW Outputs: Only one of the eight outputs is activated (LOW) based on the input combination, while the others remain HIGH.
3. Enable Inputs: Two active LOW enable inputs (G1, G2A, G2B) allow control over the device's operation, enabling or disabling the outputs.
4. Wide Supply Voltage Range: Operates within a range of 2V to 6V, making it versatile for various applications.
5. High-Speed Operation: Typically operates at speeds up to 6.5 ns, suitable for high-speed applications.
6. Low Power Consumption: Designed to have low static and dynamic power dissipation.
7. Multiple Package Options: Available in various packages, including TSSOP and SOIC, facilitating integration into different circuit layouts.
These features make the CD74HC238PWR suitable for data routing, memory address decoding, and signal demultiplexing in digital systems.

Package

The CD74HC238PWR is packaged in a TSSOP (Thin Shrink Small Outline Package) type, specifically with a 16-lead configuration.

Pinout

The CD74HC238PWR is a high-speed CMOS logic device that functions as a 3-to-8 line decoder/demultiplexer. It has 16 pins, which serve the following functions:
1. Inputs (A0, A1, A2): Pins 1, 2, and 3 (A0, A1, A2) are used to select one of the eight output lines.
2. Enable Inputs (G1, G2A, G2B): Pins 4 (G1) and 5 (G2A), 6 (G2B) are enable inputs that control the activation of the decoder. G1 must be high while G2A and G2B must be low for the decoder to function.
3. Outputs (Y0 to Y7): Pins 7 to 14 (Y0 to Y7) are the output lines, where one output will be activated (low) based on the input selection when the device is enabled.
4. VCC: Pin 15 is the power supply pin.
5. GND: Pin 8 is the ground pin.
In summary, the CD74HC238PWR is a versatile decoding component useful in various digital applications.
