| PI74HSTL1212 24-Bit, 1.8V to 3.3V Bi-Directional Level Shifting Transceiver Product Features • PI74HSTL1212 is designed for translation between 1.8V HSTL and LVCMOS • Supports 1.8V HSTL Class I Buffer • Industrial operation at to +85°C • Dual Independent 12-Bit Slice Direction Control • Packaging Pb-free & Green available : 64-pin 240-mil wide TSSOP A Product Description 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.
