M74HC693RM13TR

4 BIT BINARY COUNTER/REGISTER (3-STATE)

STMicroelectronics 

WAVEFORM 8 : PROPAGATION DELAY TIME (f=1MHz; 50% duty cycle)

M74HC693

tPLZ, tPZL

The 1KΩ load resistors sholud be connected

between outputs and VCC line and the 50pF load

capacitor should be connected between outputs

and GND line.

All inputs except G input should be connected to

VCC or GND line such that outputs will be in low

logic level while G input is held low.

WAVEFORM 9 : (f=1MHz; 50% duty cycle)

tPHZ, tPZH

The 1KΩ load resistors and the 50pF load

capacitors should be connected between each

output and GND line.

All inputs except G input should be connected to

VCC or GND line such that outputs will be in low

logic level while G input is held low.
