Fast CMOS Octal D
Registers (3-State)
Product Features:
Product Description:
• PI74FCT374/534/574/2374/2574T is pin compatible with bipolar
FAST™ Series at a higher speed and lower power
consumption
• 25Ω series resistor on all outputs (FCT2XXX only)
• TTL input and output levels
• Low ground bounce outputs
• Extremely low static power
• Hysteresis on all inputs
• Industrial operating temperature range: –40°C to +85°C
• Packages available:
– 20-pin 173 mil wide plastic TSSOP (L)
– 20-pin 300 mil wide plastic DIP (P)
– 20-pin 150 mil wide plastic QSOP (Q)
– 20-pin 150 mil wide plastic TQSOP (R)
– 20-pin 300 mil wide plastic SOIC (S)
Pericom Semiconductor’s PI74FCT series of logic circuits are produced in the Company’s 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
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.
