Buffered Common Clock Buffered Inputs Typical Propagation VCC = 5V, TA = 25oC Delay at CL = 15pF, - 14 ns (HC Types - 16 ns (HCT Types) Fanout (Over Temperature Range) Wide Operating Temperature Range . . . -55oC to 125oC Balanced Propagation Delay and Transition Times Significant Power Reduction Compared to LSTTL Logic ICs HC Types - 2V to 6V Operation - High Noise Immunity: NIL = 30%, NIH = 30%of VCC at VCC = 5V HCT Types - 4.5V to 5.5V Operation - Direct LSTTL Input Logic Compatibility, VIL= 0.8V (Max), VIH = 2V (Min) - CMOS Input Compatibility, Il ≤ 1µA at VOL, VOH The ’HC377 and ’HCT377 are octal D-type flip-flops with a buffered clock (CP) common to all eight flip-flops. All the flipflops are loaded simultaneously on the positive edge of the clock (CP) when the Data Enable (E) is Low.
