Description

Two count enables, PE and TE, in each counter are provided for n-bit cascading. In all counters reset action occurs regardless of the level of the SPE, PE and TE inputs (and the clock input, CP, in the 'HC161 and 'HCT161 types).

If a decade counter CD74HC161M is preset to an illegal state or assumes an illegal state when power is applied, CD74HC161M will return to the normal sequence in one count as shown in state diagram. The look-ahead carry feature simplifies serial cascading of the counters. Both count enable inputs (PE and TE) must be high to count.

The CD74HC161M TE input is gated with the Q outputs of all four stages so that at the maximum count the terminal count (TC) output goes high for one clock period. This TC pulse is used to enable the next cascaded stage.
