ProductDescription
Pericom Semiconductors PI74FCT series of logic circuits are pro-
duced in the Companys advanced 0.6 micron CMOS technology,
achieving industry leading speed grades.
Balanced output drivers:
±12mA
Output impedance:
The PI74FCT162Q374Tisa16-bitoctalregisterdesignedwith16D-
type flip-flops with a buffered common clock and 3-state outputs.
TheOutputEnable(xOE)andclock(xCLK) controlsareorganized
to operate as two 8-bit registers or one 16-bit register. When OE is
HIGH, the outputs are in the high impedance state. Input data
meeting the setup and hold time requirements of the D inputs is
transferredtothexOxoutputsontheLOW-to-HIGHtransitionofthe
clock input.

ThePI74FCT162Q374Tisdesignedwithcurrentlimitingresistorsat
its outputs to control the output edge rate resulting in lower ground
bounce and undershoot. This device features a typical output
impedance of 35Ω eliminating the need for external terminating
resistorsformostbusinterfaceapplications.Thisnoisesuppression
