Description

The CD54AC193/3A and CD54ACT193/3A are up/down binary counters with separate up/down clocks. These devices utilize the Harris Advanced CMOS Logic technology. Presetting the counter to the number on preset data inputs (P0-P3) is accomplished by a LOW asynchronous parallel load input (

PL). The counter is incremented on the LOW-to-HIGH transition of the Clock-Up input (and a HIGH level on the Clock-Down input) and decremented on the LOW-to-HIGH transition of the Clock-Down input (and a HIGH level on the Clock-Up input). A HIGH level on the Reset input overrides any other input to clear the counter to its zero state. The

TCU (carry) output goes LOW half a clock period before the zero count is reached and returns to a HIGH level at the zero count. The

TCD (borrow) output in the count down mode likewise goes LOW half a clock period before the maximum count (15 counts) and returns to HIGH at the maximum count. Cascading is effected by connecting the

TCU and TCD outputs of a less signiﬁcant counter to the Clock-Up and Clock-Down inputs, respectively, of the next most signiﬁcant counter.

The CD54AC193/3A and CD54ACT193/3A are supplied in 16-lead dual-in-line ceramic packages (F sufﬁx).s
