Présentation
Description
Key features include:
1. Dual-supply Operation: The device operates with two independent power supplies, allowing for seamless voltage level translation.
2. Direction Control: It has a direction control pin (DIR) to dictate the data flow direction, which can be from A to B or B to A.
3. High-Speed Performance: It ensures minimal propagation delay, making it suitable for high-speed data transfer applications.
4. Low Power Consumption: Designed to maintain low power usage, which is crucial for battery-operated devices.
The SN74AXC4T245PWR is ideal for mixed-voltage system interfacing in applications like mobile devices, computing peripherals, and communication systems.
Equivalent
1. NXP 74LVC8T245: An 8-bit level shifting transceiver.
2. ON Semiconductor FXMA2102: A dual-supply translator.
3. Microchip Technology MCP23S08: A general-purpose I/O expander with open-drain outputs.
These alternatives provide similar level-shifting and transceiver functions, though specifications and additional features might slightly vary. Always check the datasheet to ensure compatibility with your specific application.
Features
1. Wide Voltage Range: Supports operation from 0.65 V to 3.6 V on both VCCA and VCCB power supply pins, facilitating compatibility between devices with different voltage levels.
2. High-Speed Translation: Capable of translating signals between different voltage levels without sacrificing speed, supporting data rates up to 500 Mbps.
3. Direction Control: Features a direction-control input (DIR) that determines the direction of data flow, making it adaptable for various applications.
4. OE Control: Includes an output-enable (OE) input for disabling outputs, allowing for bus isolation or signal flow control.
5. Low Power Consumption: Designed for minimal power usage, contributing to energy efficiency in battery-powered applications.
6. Ioff Supports Partial-Power-Down: Prevents damage by ensuring no backflow of current when the device is powered down.
7. Package and Mounting: Available in a TSSOP package for compact and easy surface mounting.
These features make it suitable for applications in portable devices, communication systems, and equipment requiring reliable voltage level translation.
Pinout
Key features include:
- VCCA and VCCB Dual Power Supplies: These independently configurable voltage supplies allow for interfacing devices with different voltage levels.
- DIR Pin: Determines the direction of data flow. When DIR is high, data transmits from A to B; when DIR is low, data transmits from B to A.
- OE Pin: Output Enable. When OE is low, outputs are enabled; when high, outputs are in high-impedance state.
- 4-bit Bus Transceiver: Facilitates 4-bit data exchange in both directions.
This device is commonly used in applications requiring voltage translation and data buffering, such as interfacing sensors or peripherals with microprocessors operating at different voltage levels.
