Fast CMOS Octal D Flip-Flop With Master Reset

Pericom Semiconductors PI74FCT series of Logic circuits are pro- duced in the Companys advanced 0.6/0.8 micron CMOS technology, achieving industry leading speed grades. All PI74FCT2XXX devices have a built-in 25-ohm series resistor on all outputs to reduce noise because of reflections, thus eliminating the need for an external terminating resistor. The PI74FCT273T and PI74FCT2273T is an 8-bit wide octal designed with eight edge-triggered D-type Flip-Flops with individual D inputs and O outputs. The common buffered Clock (CP) and Master Reset (MR) load and resets (clear) all Flip-Flops simultaneously. The Register is fully edge-triggered. The D input state, one setup time before the LOW-to-HIGH Clock transition, is transferred to the corresponding flip-flop's O output. All outputs will be forced LOW independently of Clock or Data inputs by a LOW voltage level on the MR input. By Pericom Semiconductor Corporation
