DYNAMIC ELECTRICAL CHARACTERISTICS (Tamb = 25°C, CL = 50pF, RL = 200KΩ, tr = tf = 20 ns)

(*) Typical temperature coefficient for all VDD value is 0.3 %/°C.

DIGITAL TIMER APPLICATION

A positive MASTER RESET pulse clears the

counter and latch. The Output goes high and

keeps up till the number of pulses, selected by A

and B , are counted. This circuit is retriggerable

and is as accurate as the input frequency. If a

more accurate circuit is desired, an external clock

can be used on pin 3. A set-up time equal to the

width

of

the

one

shot

output

is

required

immediately following initial power up, during

which time the output will be high
