PI74HSTL1212 Datasheet | Pericom Semiconductor

Features • PI74HSTL1212 is designed for translation between 1.8V HSTL and LVCMOS • Supports 1.8V HSTL Class I Buffer • Industrial operation at –40°C to +85°C • Dual Independent 12-Bit Slice Direction Control • Packaging: 64-pin plastic 240-mil TSSOP (A) Product Description Peri Semiconductor’s HSTL series of logic circuits are produced using the pany’s advanced submicron CMOS technology, achieving industry leading performance. Peri 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 munications between HSTL and LVTTL/LVCMOS data buses. Truth Table (Each 12-bit slice) Inputs XD AB / XD BA H (TTL) L (TTL)...
