High-Speed CMOS Logic

Presettable Synchronous 4-Bit Up/Down Counters

September 1997 - Revised October 2003

Presetting the counter to the number on the preset data inputs

(P0-P3) is accomplished by a LOW asynchronous parallel

Features

• Synchronous Counting and Asynchronous

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 MR input overrides any other input to clear

the counter to its zero state. The Terminal Count up (carry)

goes low half a clock period before the zero count is reached

and returns to a high level at the zero count. The Terminal

Count Down (borrow) in the count down mode likewise goes

low half a clock period before the maximum count (9 in the

192 and 15 in the 193) and returns to high at the maximum

count. Cascading is effected by connecting the carry and

borrow outputs of a less significant counter to the Clock-Up

and Clock-Down inputs, respectively, of the next most

significant counter.

If a decade counter is preset to an illegal state or assumes an

illegal state when power is applied, it will return to the normal

sequence in one count as shown in state diagram.
