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.
