DESCRIPTION
The
HCC40192B, HCC40193B,
(extended tem-
perature range) and the
HCF40192B, HCF40193B
(intermediate temperature range) are monolithic in-
tegrated circuits, available in 16-lead dual in-line
plastic or ceramic package and platic micro pack-
age. The
HCC/HCF40192B
Presettable BCD
Up/Down Counter and the
HCC/HCF40193B
Pres-
ettable Binary Up/Down Counter each consist of 4
synchronously clocked, gated ”D” type flip-flops
connected as a counter. The inputs consist of 4 in-
dividual jam lines, a PRESET ENABLE control, in-
dividual CLOCK UP and CLOCK DOWN signals
and a master RESET. Four buffered Q signal out-
puts as well as CARRY and BORROW outputs for
multiple-stage counting schemes are provided. The
counter is cleared so that all outputs are in a low
state by a high on the RESET line. A RESET is ac-
complished asynchronously with the clock. Each
output is individually programmable asynchron-
ously with the clock to the level on the corresponding
jam input when thePRESET ENABLE control is low.
The counter counts up one count on the positive
clock edge of the CLOCK UP signal provided the
CLOCK DOWN line is high. The counter counts
down one count on the positive clock edge of the
CLOCK DOWN signal provided the CLOCK UP line
