IDT54/74FCT574T/AT/CT
FEATURES:
DESCRIPTION:
• Std., A, and C grades
The FCT574T is an 8-bit register built using an advanced dual metal
CMOStechnology.Theseregisters consistofeightD-typeflip-flops witha
bufferedcommonclockandbuffered3-stateoutputcontrol.Whentheoutput
enable(OE)inputis low,theeightoutputs areenabled.WhentheOEinput
is high,the outputs are inthe high-impedance state.
• Low input and output leakage ≤1µA (max.)
• CMOS power levels
• True TTL input and output compatibility:
– VOH = 3.3V (typ.)
– VOL = 0.3V (typ.)
