Product Description:
Pericom Semiconductor's PI74FCT series logic circuits produced Company's advanced micron CMOS technology, achieving industry leading speed grades. PI74FCT2XXX devices have built-in series resistor outputs reduce noise because reflections, thus eliminating need external terminating resistor. PI74FCT543T/544T PI74FCT2543T 8-bit wide non-inverting transceiver designed with sets eight D-type latches with separate input output controls each set. data flow from example, A-to-B Enable (CEAB) input must order enter data from A0-A7 take data from B0-B7, indicated Truth Table. With CEAB LOW, signal makes A-to-B latches transparent; subsequent LOW-to-HIGH transition LEAB signal puts latches storage mode their outputs longer change inputs. With CEAB OEAB both LOW, 3-state output buffers active reflect data present output latches. Control data from similar, uses CEAB, LEAB, OEAB inputs. PI74FCT543T noninverting PI74FCT544T.
