This arrangement permits translation from a 1.5-2.5V to 3.3V environment and vice versa. The control pins, OE and DIR are controlled by VCCB . • Industrial operation at –40°C to +85°C • Packag (Pb-free & Green available): – 48-pin plastic 240-mil TSSOP (A) – 48-pin plastic 173-mil TVSOP (K) The PI74AVC164245LA is designed for asynchronous communication between data buses. Truth Table (each 8-bit section) To ensure the high impedance state during power up or power down, the output-enable (OE) input should be tied to VCC through a pullup resistor: the minimum value of the resistor is determined by the current-sinking capability of the driver.
