Description
The SN74LVC2T45DCUR supports automatic direction sensing, eliminating the need for a direction-control signal, which simplifies design and reduces the number of control lines. Its high-speed operation, low power consumption, and low propagation delay make it suitable for various applications, including interfacing between logic devices, microcontrollers, and microprocessors with differing voltage needs. The device is packaged in a small-outline dual-row (VSON) package, making it ideal for space-constrained applications. It also includes features like power-down protection and Ioff to prevent reverse current when the device is powered down.
Equivalent
1. NXP 74LVC2T45 - Dual supply translating transceiver.
2. ON Semiconductor NL27WZ17 - Dual non-inverting buffer/line driver.
3. Fairchild Semiconductor FXLA2202 - Dual-supply level translator.
Ensure compatibility by checking the datasheet specifications like voltage levels, package type, and pin configuration when considering alternatives.
Features
1. Voltage-Level Translation: It operates with dual-supply voltages, allowing for voltage-level translation between 1.65 V to 5.5 V on both A and B ports, making it versatile for interfacing different logic levels in mixed-voltage systems.
2. Bidirectional Data Flow: The device supports direction-controlled, bidirectional data flow, enabling flexible data transfer between A and B ports.
3. High-Speed Operation: It offers high-speed operation with a low propagation delay, suitable for fast data transmission.
4. Low Power Consumption: Designed to minimize power usage, it features partial power-down capability, making it energy efficient for portable and battery-powered applications.
5. Bus-Hold Feature: This prevents bus floating by maintaining the last known state of the bus lines.
6. I/O Protection: Provides protection against electrostatic discharge (ESD) and supports hot insertion.
7. Compact Package: Available in a small, space-saving package (VSSOP), suitable for compact circuit designs.
These features make the SN74LVC2T45DCUR ideal for applications requiring reliable voltage translation and efficient data communication across different logic levels.
Pinout
1. VCCA: Supply voltage for the A port (1.65 V to 5.5 V).
2. A1: Data input/output for channel 1, referenced to VCCA.
3. A2: Data input/output for channel 2, referenced to VCCA.
4. DIR: Direction control. When high, data is transmitted from A to B; when low, data is transmitted from B to A.
5. VCCB: Supply voltage for the B port (1.65 V to 5.5 V).
6. B1: Data input/output for channel 1, referenced to VCCB.
7. B2: Data input/output for channel 2, referenced to VCCB.
8. GND: Ground reference for the device.
The SN74LVC2T45DCUR is versatile and supports bidirectional level shifting, making it invaluable in mixed-voltage environments.
