DESCRIPTION
HCF40193B is a monolithic integrated circuit
fabricated
in
Metal
Oxide
Semiconductor
technology available in DIP and SOP packages.
HCF40193B Presettable Binary Up/Down Counter
consists of 4 synchronously clocked, GATED "D"
type flip-flops connected as a counter. The inputs
consist of four 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
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
accomplished
asynchronously with the clock. Each output is
individually programmable asynchronously with
the clock to the level on the corresponding jam
input when the PRESET 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 is high. The CARRY and BORROW signals
are high when the counter counts up or down. The
CARRY signal goes low one-half clock cycle after
the counter reaches its maximum count in the
count-up mode. The BORROW signal goes low
