Overview
TECHNICAL DATA IW4020B 14 Stage Ripple-Carry Binary Counter/Divider High-Voltage Silicon-Gate CMOS The IW4020B is ripple-carry binary counter.
All counter stages are masterslave flip-flops.
The state of a counter advances one count on the negative transition of each input pulse; a high level on the RESET line resets the counter to its all zeros state.
Schmitt trigger action on the input-pulse line permits unlimited rise and fall times.
• Operating Voltage Range: 3.
0 to 18 V • Maximum input current of 1 µA at 18 V over full package-temperature range; 100 nA at 18 V and 25°C • Noise margin (over full package temperature range): 1.
