Description
The CD4514BE is equipped with a latch enable (LE) input that captures data on the input lines and holds it until the latch is disabled, allowing stable data output even when input conditions change. An enable (E) input controls whether the decoder is active; the outputs are disabled when it is low.
Notable for its low power consumption and high noise immunity, it operates over a wide voltage range (3V to 15V), making it versatile for various applications. The CD4514BE is commonly used in applications needing multiplexing, demultiplexing, or decoding, such as memory address decoding, data routing, and signal selection tasks in embedded systems and digital electronics.

2. HEF4514B
3. MC14514B
4. TC4514BP
These alternatives offer similar functionality and are generally compatible, though they may differ in operating voltage and speed. Always check the datasheet for specific electrical characteristics and pin configurations.
Features
Key features include:
1. BCD to Decimal Decoding: Converts BCD input to a single active output among 16.
2. Latch Functionality: Data can be stored using the latch, which is controlled by the latch enable input.
3. Strobe Input: Allows for enabling or disabling the outputs.
4. Wide Operating Voltage Range: Typically from 3V to 15V, making it suitable for a variety of power supply conditions.
5. Low Power Consumption: Due to CMOS technology.
6. High Noise Immunity: Provides reliable operation in noisy environments.
7. Output Drive Capability: Can directly drive LEDs and other loads.
These features make the CD4514BE suitable for applications like digital displays, multiplexing, and data routing in digital systems.
Pinout
Here is a brief overview of its pin configuration and functions:
- Pins 1-4 (A, B, C, D): These are the input pins for binary data.
- Pin 5 (INHIBIT): This pin disables all outputs when set high.
- Pin 6 (STROBE): This pin is used to latch data; outputs change state only when strobe is low.
- Pins 7-11 and 13-17: These are the output pins (O0 to O15) which correspond to the decoded input.
- Pin 12 (VSS): Ground.
- Pin 18 (VDD): Positive supply voltage.
- Pin 19 (LATCH ENABLE): This pin enables the latching of input data when high.
- Pins 20-24: Not used for decoding function, often marked NC (No Connection).
The device is typically used in digital circuits where binary to decimal decoding is required, such as in microprocessor systems.
