DESCRIPTI ON
The HCC40192B, HCC40193B, (extended tem-
peraturerange) and the HCF40192B, HCF40193B
(intermediate temperature range) are monolithic integrated circuits, available in 16-lead dual in-line
plastic or ceramic package and platic micro package. The HCC/HCF40192B Presettable BCD
Up/DownCounter and theHCC/HCF40193B Pres-
ettable BinaryUp/Down Counter each consist of 4
synchronously clocked, gated ”D” type flip-flops
connected as a counter. The inputs consist of 4 individual jam lines,a PRESET ENABLE control, individual CLOCK UP and CLOCK DOWN signals
and a master RESET. Four buffered Q signal outputs as well as CARRY and BORROW outputs for
multiple-stage counting schemesareprovided. The
counter is cleared so that all outputs are in a low
stateby a high on the RESET line. A RESET isaccomplished asynchronously with the clock. Each
output is individually programmable asynchronouslywith theclocktothelevelonthecorresponding
jaminputwhenthePRESETENABLEcontrol islow.
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
CLOCKDOWN signal provided the CLOCK UP line

multiple packages is easily accomplished without
the need foradditional externalcircuitrybytying the
BORROW and CARRY outputs to the CLOCK

succeeding package.
