HIGH SPEED CMOS LOGIC IC ELM7SH14xB Schmitt Inverter

HIGH SPEED CMOS LOGIC IC
ELM7SH14xB Schmitt Inverter
■General description
ELM7SH14xB is CMOS schmitt inverter which is suitable for battery-operated devices because of its low
voltage and ultra high speed operation. The low power consumption contributes to longer battery life, which
allows long time operation of devices. The internal circuit which provides high noise immunity and stable
output is composed of 3 stages, including buffered output.

* Cpd is IC's inner equivalent capacity which is calculated from non-loaded operating current consumption referred to test
circuit. Averaged operating current consumption at non load is calculated as following formula: Idd(opr)=Cpd • Vdd • fin+Idd
