MC74F568, (MC74F568 / MC74F569) 4-BIT BIDIRECTIONAL COUNTERS(WITH 3-STATE OUTPUTS)

The F568 counts modulo-10 in the BCD (8421) sequence.

From state 9 (HLLH) it will increment to 0 (LLLL) in the Up mode; in Down mode it will decrement from 0 to 9.The F569 counts in the modulo-16 binary sequence.

From state 15 it will increment to state 0 in the Up mode; in the Down mode it will dec
