ELM-TECH ELM7SH32XB

HIGH SPEED CMOS LOGIC IC
ELM7SH32xB
2-input OR gate
■General description　ELM7SH32xB is CMOS 2-input OR gate 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
： Idd=1.0μA(Max.)(Top=25℃ )
・ Wide power voltage range
： 2.0V～5.5V
・ Wide input voltage range
: Vih=5.5V(Max.)(Vdd=0～5.5V)
・ High speed
： Tpd=2ns(Typ.) (Vdd=5.0V)
・ Small package
: SOT-25, SSOT-25(SC-88A)
・ Same function and pin configuration as ELM7SxxB
■Application
・ Cell phones
・ Digital cameras
・ Portable electrical appliances like PDA, etc.
・ Computers and peripherals
・ Digital electrical appliances like LCD TV sets, DVD recorders/players, STB, etc.
・ Modification inside print board, adjustment of timing, solution to noise
・ Power voltage change from 5V to 3V

* 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
