●Product Description
●Pericom Semiconductor’s PI74LPT series of logic circuits are produced in the Company’s advanced 0.6 micron CMOS technology, achieving industry leading speed grades.
●The PI74LPT646 and PI74LPT652 are designed with a bus transceiver with 3-state D-type flip-flops and control circuitry arranged for multiplexed transmission of data directly from the data bus or from the internal storage registers. The PI74LPT652 utilizes GAB and GBA signals to control the transceiver functions. The PI74LPT646 utilizes the enable control (G) and direction pins (DIR) to control the transceiver functions. SAB and SBA control pins are used to select either real-time or stored data transfer. The circuitry used for select control will eliminate the typical decoding glitch that occurs in a multiplexer during the transition between real-time and stored data. A low input level selects real-time data and a high selects stored data.
