HIGH SPEED CMOS LOGIC IC
Schmitt Inverter
ELM7SH14xB
■General descriptionꢀ
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.
■Features
・ Same electrical characteristic and high speed operation as 74VHC series
・ Low consumption current
・ Wide power voltage range
・ Wide input voltage range
・ High speed
