Pericom Semiconductor’s PI74HSTL1212 consists of two 12-Bit bidirectional non-inverting tranceivers with two separate supply rails, A-Port (VCCA) set at 1.8V, and B-Port (VCCB) set at 3.3V. Each set of 12 tranceivers allows translation from a 1.8V to 3.3V and back again. The control inputs 1DAB/1DBA and 2DAB/2DBA allows independent 12-Bit slice direction control for greater flexibility. The PI74HSTL1212 is particularly useful for asynchronous communications between HSTL and LVTTL/LVCMOS data buses. Truth Table (Each 12-bit slice) Inputs XD AB / X...
