High Speed CMOS Logic
Dual 4 -Stage Binary Counter
September 1997
Features
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
• Fully Static Operation
• Buffered Inputs
• Common Reset
• Negative-Edge Clocking
• Typical fMAX = 60 MHz at VCC = 5V, CL = 15pF,
TA = 25oC
Description
The Harris CD74HC393 and CD74HCT393 are 4-stage
ripple-carry binary counters. Al counter stages are masterslave flip-flops. The state of the stage advances one count
on the negative transition of each clock pulse; a high voltage
level on the MR line resets all counters to their zero state. All
inputs and outputs are buffered.
• Fanout (Over Temperature Range)
- Standard Outputs . . . . . . . . . . . . . . . 10 LSTTL Loads
- Bus Driver Outputs . . . . . . . . . . . . . 15 LSTTL Loads
• Wide Operating Temperature Range . . . -55oC to 125oC
• Balanced Propagation Delay and Transition Times
Ordering Information
• Significant Power Reduction Compared to LSTTL
Logic ICs
