can you explain the working of SN54196 IC?

Why there are 3 inputs for divide by 5 counter? Can the IC divide 3 frequencies simultaneously?

Ayovi,

The 54196 has two counters (2 clocks); one divides by 2 the other by 5.
The Load and CLR affect both counters.

It can divide 2 frequencies simultaneously.

There are 2 clk inputs, 4 count inputs (ABCD), 1 CLR input, 1 LOADn input, and 4 outputs Q(ABCD).

This device was released in 1976, and there is little additional data on operation.

I suspect the 3 outputs are the 3 bits of the encoded quinary counter.

See Wikipedia article on bi-quinary counters.

Wade
