概述

Description

The CD4514BE is a 4-to-16 line decoder/demultiplexer, part of the CD4000 series of CMOS logic ICs. It converts a 4-bit binary input into one of 16 outputs, enabling the selection of a specific output line corresponding to the binary input value. The device is designed for low power consumption and high noise immunity, making it suitable for various digital applications, including memory address decoding and data routing.
Key features include active-low outputs, which mean that when a particular output is selected, it will be driven low, while all other outputs remain high. The CD4514BE also includes enable inputs to control the operation of the decoder. It operates over a wide voltage range, typically between 3V to 15V, and can handle a wide range of temperatures.
Overall, the CD4514BE is efficient for applications requiring simple binary decoding and is widely used in digital circuit designs.

Features

The CD4514BE is a 4-to-16 line decoder/demultiplexer featuring a wide range of applications in digital circuits. Key features include:
1. 4-bit Input: It accepts a 4-bit binary input to decode into 16 distinct output lines.
2. Active-High Outputs: Outputs go high based on the binary input, facilitating straightforward logic integration.
3. Enable Inputs: Two enable inputs (E1 and E2) control the operation, allowing for flexible design configurations.
4. Low Power Consumption: Designed for low power operation, making it suitable for battery-operated devices.
5. High Noise Immunity: Robust against noise, ensuring reliable performance in various environments.
6. Wide Supply Voltage Range: Operates typically from 3V to 15V, accommodating different circuit designs.
7. TTL Compatible: Compatible with TTL logic levels, ensuring ease of interfacing with other digital ICs.
8. Temperature Range: Functional over a wide temperature range, suitable for diverse applications.
These features make the CD4514BE ideal for applications in data routing, memory selection, and other digital signal processing tasks.

Package

The CD4514BE is typically packaged in a 16-pin dual in-line package (DIP). This package type allows for easy insertion into breadboards and sockets, making it suitable for prototyping and circuit design. Additionally, it may also be available in surface mount configurations.

Pinout

The CD4514BE is a 4-to-16 line decoder/demultiplexer with a total of 16 pins. Its pin configuration includes:
1. Input Pins: 4 address inputs (A0, A1, A2, A3) that determine which output is activated.
2. Enable Pins: Two enable inputs (G1 and G2) that control the operation of the device. G1 must be high for the decoder to function, while G2 must be low.
3. Output Pins: 16 active low outputs (Y0 to Y15) that correspond to the binary value of the input addresses.
4. Ground (VSS): Common ground connection.
5. Power Supply (VDD): Positive power supply connection.
The CD4514BE is typically used in applications requiring address decoding and data routing, allowing the selection of one of the 16 outputs based on the 4-bit input.
