74ALVC245 Low Voltage Bidirectional Transceiver with 3.6V Tolerant Inputs and Outputs Features General Description ■ 1.65V to 3.6V VCC supply operation The ALVC245 contains eight non-inverting bidirectional buffers with 3-STATE outputs and is intended for bus oriented applications. The T/R input determines the direction of data flow. The OE input disables both the A and B ports by placing them in a high impedance state. ■ 3.6V tolerant inputs and outputs ■ Power-off high impedance inputs and outputs ■ Supports Live Insertion and Withdrawal(1) ■ tPD: – 3.4ns max. for 3.0V to 3.6V VCC – 3.9ns max. for 2.3V to 2.7V VCC – 6ns max. for 1.65V to 1.95V VCC ■ Uses patented Quiet Series noise/EMI reduction circuitry ■ Latchup conforms to JEDEC JED78 ■ ESD performance: – Human body model > 2000V – Machine model > 200V Note: 1. To ensure the high impedance state during power up and power down, OEn should be tied to VCC through a pull up resistor. The minimum value of the resistor is determined by the current sourcing capability of the driver. The 74ALVC245 is designed for low voltage (1.65V to 3.6V) VCC applications with I/O compatibility up to 3.6V. The 74ALVC245 is fabricated with an advanced CMOS technology to achieve high-speed operation while maintaining low CMOS power dissipation.

The device may not function or be operable above the recommended operating conditions and stressing the parts to these levels is not recommended. In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability. The absolute maximum ratings are stress ratings only.
