PI74AVC164245
16-Bit 1.8-2.5V to 3.3V Level Shifting Transceiver with 3-State Outputs
Product Features
PI74AVC164245 is designed for low voltage operation: 1.8V - 2.5V to 3.3V Industrial operation at 40C to +85C Packages available: 48-pin plastic 300 mil SSOP (V) 48-pin plastic 240 mil TSSOP (A) 48-pin plastic 173 mil TVSOP (K)
Product Description
Pericom Semiconductors AVC series of logic circuits are produced using the Companys advanced 0.35 micron CMOS technology, achieving industry leading performance. Pericom Semiconductors PI74AVC164245, a 16-bit (dual-octal) noninverting bus transceiver, contains two separate supply rails: B port (VCCB), set at 3.3V, and A port (VCCA), set to operate at 1.8-2.5V. This arrangement permits translation from a 1.8-2.5V to 3.3V environment and vice versa. The PI74AVC164245 is designed for asynchronous communication between data buses.

Inputs OE L L H DIR L H X Ope ration B data to A bus A data to B bus Isolation
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.
