SN74LVCC3245ADBR

The SN74LVCC3245ADBR is a high-performance, low-voltage, 16-bit addressable priority encoder from Texas Instruments. This device is designed to provide a flexible and efficient solution for addressing priority encoding applications in digital systems.

Description:

The SN74LVCC3245ADBR is a 16-input priority encoder that takes a 4-bit binary input and converts it into a unique 16-bit priority code. It is designed to operate with a supply voltage range of 1.65V to 3.6V, making it suitable for low-voltage applications. The device is available in a 20-pin TSSOP package.

Features:

1. 16-input priority encoder
2. Low-voltage operation (1.65V to 3.6V)
3. Active-low enable (G) input
4. Active-high clear (CLR) input
5. Active-low priority select (PS) input
6. Open-drain output for interfacing with other devices
7. Active-low interrupt output (IRQ)
8. Active-low buffer overflow (OE) output
9. Programmable priority through the PS input
10. Low power consumption

Applications:

1. Microcontrollers and microprocessors with multiple interrupt sources
2. Digital signal processors (DSPs) with multiple interrupt sources
3. Industrial control systems
4. Telecommunication systems
5. Automotive control systems
6. Networking and data communication systems
7. Consumer electronics with multiple priority levels

In summary, the SN74LVCC3245ADBR is a versatile and efficient priority encoder that can be used in various digital systems requiring priority encoding. Its low-voltage operation, active-low enable, and clear inputs, along with the active-low priority select input, make it a suitable choice for a wide range of applications.
