Pin Names:

Vdd - Positive Supply Voltage [BV to 15V]

Vss - Ground

Q1, Q2, Q3, Q4, Q5, Q8, Q7 - Outputs

CLK - Clock or Input

RST - Reset

N.C. - Not Connected

Truth Table: none

 

Operation Mode:

RST is held at ground.

The circuit advances one count in the positive transition of the clock signal.

The outputs divide the clock signal by powers of two according the RST is done by putting the pin to the “1 ” logic level [positive].
