Fast CMOS Octal D Registers (3-State)
Product Description:
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.

Notes: 1. For Max. or Min. conditions, use appropriate value specified under Electrical Characteristics for the applicable device type. 2. Typical values are at Vcc = 5.0V, +25°C ambient and maximum loading. 3. Not more than one output should be shorted at one time. Duration of the test should not exceed one second. 4. This parameter is determined by device characterization but is not production tested.
