Description
The ’HC192, ’HC193 and ’HCT193 are asynchronously
presettable BCD Decade and Binary Up/Down synchronous
counters, respectively.

Presetting the counter to the number on the 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 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.
