- Direct LSTTL Input Logic Compatibility,
VIL= 0.8V (Max), VIH = 2V (Min)
- CMOS Input Compatibility, Il ≤ 1µA at VOL, VOH
• Buffered Common Clock
• Buffered Inputs
• Typical Propagation Delay = 17ns at CL = 15pF,
VCC = 5V, TA = 25oC
• Fanout (Over Temperature Range)
Description
- Standard Outputs . . . . . . . . . . . . . . . 10 LSTTL Loads
- Bus Driver Outputs . . . . . . . . . . . . . 15 LSTTL Loads
The Harris CD74HC377 and CD74HCT377 are octal D-type
flip-flops with a buffered clock (CP) common to all eight flipflops. All the flip-flops are loaded simultaneously on the
positive edge of the clock (CP) when the Data Enable (E) is
Low.
• Wide Operating Temperature Range . . . -55oC to 125oC
• Balanced Propagation Delay and Transition Times
• Significant Power Reduction Compared to LSTTL
Logic ICs
Ordering Information
• HC Types
- 2V to 6V Operation
- High Noise Immunity: NIL = 30%, NIH = 30%of VCC at
