Features

The SN74AVCH24T245NMUR is a dual-supply, 16-bit bidirectional level translator designed for high-speed applications. Key features include:
1. Bidirectional Level Translation: Supports voltage level shifting between two different power supply domains (e.g., 1.2V to 3.6V).
2. High-Speed Operation: Capable of operating at data rates up to 110 Mbps.
3. Wide Supply Voltage Range: Accepts VCCA from 1.2V to 3.6V and VCCB from 1.2V to 3.6V, allowing flexibility in interfacing with various logic levels.
4. Low Power Consumption: Features a low quiescent current, making it efficient for battery-operated devices.
5. Active Bus Hold: Ensures that unused inputs are held at a valid logic level, improving noise immunity.
6. Multiple Configurations: Can be configured for different data flow directions based on the control pins.
7. ESD Protection: Provides robust ESD protection, ensuring reliability in harsh environments.
Overall, the SN74AVCH24T245NMUR is ideal for applications requiring reliable communication between devices operating at different voltage levels.

Package

The SN74AVCH24T245NMUR is packaged in a 20-pin TSSOP (Thin Shrink Small Outline Package) format.

Pinout

The SN74AVCH24T245NMUR is a dual-bit bidirectional voltage-level translator with a pin count of 20. It is designed to facilitate communication between devices operating at different voltage levels, typically between 1.2V and 5.5V.
The primary function of this device is to translate input signals from one voltage level to another, making it ideal for interfacing devices with different supply voltages. It features two independent channels (A and B) with each channel containing two bits. The device supports high-speed data transfer and has separate direction control for each channel.
Key pins include:
- A1, A2: Inputs from the lower voltage side.
- B1, B2: Outputs to the higher voltage side.
- VCCA/VCCB: Supply voltage pins for the lower and higher voltage sides, respectively.
- DIR: Direction control pin to set the data flow.
This device is commonly used in mixed-voltage systems, such as connecting 5V microcontrollers to 3.3V sensors or peripherals.
