| PI74STX2G4245 2-Bit Level Shifting Buffer/Transceiver with Configurable Dual Supply Voltage Features * Operation Voltage: 1.65V VCCA 3.6V 2.3V VCCB 5.5V VCCA VCCB * High Speed: tpd = 5ns typical into 30pF @ 3V VCC * Power down high-impedance inputs and outputs * High output drive: 12mA at 3V VCCA/VCCB 24mA at 5V VCCB * Industrial operation at -40C to +85C * Packaging (Pb-free & Green available): - 8-pin MSOP (U) - 12-pin TDFN (ZE) Description Pericom Semiconductor's PI74STX2G4245, a 2-bit noninverting buffer/transceiver, contains two separate supply rails:A port (VCCA), set to operate from 1.8V to 3.3V; B port (VCCB), set to operate from 2.5V to 5V. The A1 to B1 translation is configured as an unidirectional buffer; the translation between A2 and B2 is bidirectional and its direction is controlled by the DIR pin. The DIR pin is supplied by VCCB.

Stresses greater than those listed under MAXIMUM RATINGS may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect reliability. 2. The input negative voltage and output voltage ratings may be exceeded if the input and output current ratings are observed. 3. This value is limited to 6V.
