Fast Cmos 16-bit Registered/latched Transceiver With Parity Semiconductor Corporation

Pericom Semiconductors PI74FCT series of Logic circuits are pro- duced in the Companys advanced 0.8 micron CMOS technology, achieving industry leading speed grades. The PI74FCT16511T and PI74FCT162511T are high-speed, low- power 16-bit registered/latched transceiver with parity which combines D-type Latches and D-type Flip-Flops to allow data flow in transparent, latched or clocked modes. It has a parity generator/ checker in the A-to-B direction and a parity checker in the B-to-A direction. Error checking is done at the byte level with separate parity bits for each byte. One error flag for each direction (A-to-B or B-to-A) exists to indicate an error for either byte in either direction. The parity error flags which are open drain outputs, CAN be tied together and/or tied with flags from other devices to form a single error flag or interrupt. To disable the error flag during combinational transitions, a designer CAN disable the parity error flag by the OExx control pins. The operation in A-to-B direction is controlled by LEAB, CLKAB and OEAB control pins, and the operation in B-to-A direction is controlled by LEBA, CLKBA and OEBA control pins. GEN/CHK is used to select the operation of A-to-B direction, while B-to-A direction is always in checking mode. The ODD/EVEN select is common between the two directions. Independent operation CAN be achieved between the two directions by using the corresponding control lines except for the ODD/EVEN control. By Pericom Semiconductor Corporation
