File Size : 116 KB Manufacturer:AD Description: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
