概要

Description

The 74HC4514PW is a 4-to-16 line decoder/demultiplexer IC. It converts a 4-bit binary input into a one-hot output on one of the 16 output lines, which are active low. Designed using high-speed CMOS technology, it operates within a voltage range of 2V to 6V, making it compatible with various logic families.
Key features include low power consumption, improved noise margins, and the ability to drive multiple TTL loads. It also provides a direct enable input to control the decoder's operation.
The 74HC4514PW is often used in applications such as memory address decoding, data routing, and as part of larger digital circuits to expand addressable space. Its compact package type (TSSOP) makes it suitable for space-constrained designs. Overall, it is a versatile component in digital system architecture for efficient signal routing and control.

3. Low Power Consumption: Consumes significantly less power compared to TTL devices.
4. Temperature Range: Functional over a temperature range of -40°C to +125°C.
5. Active-Low Outputs: Features 16 active-low outputs, enabling straightforward interfacing with other logic devices.
6. Easy Addressing: Accepts a 4-bit binary input to decode into one of the 16 outputs.
7. Enable Input: Includes an enable input for controlling the device operation.
8. High Noise Immunity: Exhibits high noise margin, ensuring reliable operation in noisy environments.
9. Package Types: Available in various package options, such as TSSOP and SOIC.
These features make the 74HC4514PW suitable for applications in data routing, memory address decoding, and more.

Package

The 74HC4514PW is packaged in a TSSOP (Thin Shrink Small Outline Package) format, specifically a 16-lead TSSOP. This compact package type is designed for surface mounting, suitable for applications requiring space-efficient components.

Pinout

The 74HC4514PW is a 4-to-16 line decoder/demultiplexer. It has a total of 20 pins.
Pin Functions:
1. 1-4 (A0-A3): Address inputs used to select one of the 16 output lines.
2. 5 (G1): Active high enable input. When high, the decoder is enabled.
3. 6 (G2A): Active low enable input. When low, the decoder is enabled.
4. 7 (G2B): Active low enable input. When low, the decoder is enabled.
5. 8-23 (Y0-Y15): Output lines corresponding to the decoded address. Only one output will be high at a time based on the inputs A0-A3.
6. 24 (VCC): Power supply pin (typically +2V to +6V).
7. 12 (GND): Ground pin.
The device converts binary values on the input pins to a one-hot output on the Y pins, providing a compact way to decode binary numbers into individual outputs.
