Fast CMOS Octal D
Registers (3-State)
Product Description:
Pericom Semiconductor’s PI74FCT series of logic circuits are pro-
ducedintheCompany’sadvanced 0.6/0.8 micron CMOStechnology,
achieving industry leading speed grades. All PI74FCT2XXX devices
have a built-in 25 ohm series resistor on all outputs to reduce noise
resulting from reflections, thus eliminating the need for an external
terminating resistor.
The PI74FCT374T/534T/574T and P174FCT2374T/2574T are
8-bit wide octal registers designed with eight D-type flip-flops with
a buffered common clock and buffered 3-state outputs. When
output enable (OE) is LOW, the outputs are enabled. 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
transferred to the O outputs on the LOW-to-HIGH transition of the
clock input.
Device models available upon request.
