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

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

PIN CONNECTION
