No Preview Available ! HD74HC4022 Octal Counters/Dividers Description The HD74HC4022 is a four-stage Johson octal counter with built-in code converter. High speed operation and spike-free outputs are obtained by use of a Johson octal counter design. The eight decoded outputs are normally low, and go high only at their appropriate octal time period. The output changes occur on the positive-going edge of the clock pulse. This part can be used in frequency division application as well as octal counter or octal decode display applications. Features • High Speed Operation • High Output Current: Fanout of 10 LSTTL Loads • Wide Operating Voltage: VCC = 2 to 6 V • Low Input Current: 1 µA max • Low Quiescent Supply Current: ICC (static) = 4 µA max (Ta = 25°C) Function Table Clock L X H X X X: Irrelevant n < 4 ··· Carry = H n ≥ 4 ··· Carry = L Clock Enable X H L X X Reset L L L L L L H Output n n n n+1 n n+1 n Q0 1 page 19.20 20.00 Max 16 9 1 1.3 1.11 Max 8 Unit: mm 7.62 2.54 ± 0.25 0.48 ± 0.10 0.25 + – 0.13 0.05 0° – 15° Hitachi Code JEDEC EIAJ Weight (reference value) DP-16 Conforms Conforms 1.07 g 5 Page
