TECHNICAL DATA
Dual Up-Counter
High-Voltage Silicon-Gate CMOS
IW4518B
The IW4518B Dual BCD Up-Counter consists two identical,
internally synchronous 4-stage counters. The counter stages are D-type
flip-flops having interchangeable CLOCK and ENABLE lines for
incrementing on either the positive-going or negative-going transition. For
single-unit operation the ENABLE input is maintained high and the
counter advances on each positive-going transition of the CLOCK. The
counters are cleared by high levels on their RESET lines.
The counter can be cascaded in the ripple mode by connecting Q4 to
the enable input of the subsequent counter while the CLOCK input of the
latter is held low.
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):
1.0 V min @ 5.0 V supply
2.0 V min @ 10.0 V supply
2.5 V min @ 15.0 V supply
