Dual Decade Counter

COUNTER fabricated with silicon gate C

LSTTL while maintaining the CMOS low power dissipation.

a divide-by-two and a divide-by-five counter. The divide-by-two

counter is incremented on the negative going transition of clock A

( CKA ). The divided-by-five counter is incremented on the

negative going transition of clock B ( CKB ). The counter can be

cascaded to form decade, bi-quinary, or various combinations up

to a divide-by-100 counter. When the CLR input is set high, the

Q outputs are set to low independent of the clock inputs.
