概述

Description

The CD4514BM is a 4-to-16 line decoder/demultiplexer, which means it can take a 4-bit binary input and convert it into one of 16 outputs. It is part of the CD4000 series of CMOS logic ICs, known for their low power consumption and high noise immunity.
Key features include:
- Input: 4 binary inputs (A0 to A3).
- Outputs: 16 active LOW outputs (Y0 to Y15), where only one output is activated based on the binary input.
- Enable Inputs: Two enable pins (E1, E2) control the active state of the decoder, allowing for cascading or multiplexing applications.
- Operating Voltage: Typically operates between 3V and 15V.
- Speed: Suitable for moderate-speed applications.
Applications for the CD4514BM include memory address decoding, data routing, and expanding the number of outputs in digital circuits. Its versatility and ease of use make it a popular choice in both educational and industrial settings.

Features

The CD4514BM is a 4-to-16 line decoder/demultiplexer with the following features:
1. Input Lines: It has 4 binary inputs (A0 to A3) that enable 16 output lines (Y0 to Y15).
2. Active Low Outputs: The outputs are active low, meaning that the selected output is pulled low while all others remain high.
3. Enable Inputs: It includes two enable pins (E1 and E2) that must be active for the decoder to function; both must be low for the outputs to change.
4. High-Speed Operation: Designed for fast response times, it operates at high speeds suitable for digital applications.
5. Wide Voltage Range: Operates typically from 3V to 15V, allowing compatibility with various logic levels.
6. Low Power Consumption: It has low static and dynamic power consumption, making it suitable for battery-operated devices.
7. TTL/CMOS Compatible: Compatible with both TTL and CMOS logic families, allowing easy integration into existing designs.
This device is commonly used in memory address decoding, data routing, and other digital applications.

Package

The CD4514BM is typically available in a 16-pin dual in-line package (DIP) format. It can also be found in other package types such as surface mount (e.g., SOIC) depending on the manufacturer.

Pinout

The CD4514BM is a 4-to-16 line decoder/demultiplexer with a pin count of 24 pins. It is used to convert a binary input (4 bits) into a corresponding one of 16 outputs.
Pin Functions:
1. Inputs:
- A0, A1, A2, A3 (Pins 1-4): Binary input lines used to select one of the 16 outputs.
- G1 (Pin 5): Active HIGH enable input.
- G2A, G2B (Pins 6, 7): Active LOW enable inputs.
2. Outputs:
- Y0 to Y15 (Pins 8-15, 20-23): Output lines where one output is activated (LOW) based on the binary input.
3. Power:
- VDD (Pin 16): Positive power supply.
- VSS (Pin 8): Ground connection.
4. Other:
- NC (No connect) pins (Pins 17-19): Not connected to any internal circuitry.
The CD4514BM is commonly used in applications requiring address decoding and data routing.
