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 4synchronously clocked,gated ”D”type flip-flops connected as a counter.The inputs consist of 4in-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-ouslywith theclock 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

is high.The CARRY and BORROW signals are high when the counter is counting 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 one-half clock cycle after the counter reaches its minimum count in the count-down mode.Cascading of multiple packages is easily accomplished without the need for additional external circuitry by tying the BORROW and CARRY outputs to the CLOCK DOWN and CLOCK UP inputs,respectively,of the succeeding package.
