High speed CMOS logic IC ELM7SHT04xB TTL input inverter

http://www.elm-tech.com■General description

ELM7SHT04xB is CMOS inverter with TTL input which is suitable for battery-operated devices because ofits 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 andstable output is composed of 3 stages, including buffered output. All input pins have an input tolerant circuit
configuration. In other words, there is no diode on the positive side (forward from input to Vdd), so it ensuresthat 0 to 5.5 V can be applied to the input pins without regard to the supply voltage.

■Features• TTL level input: Vil = 0.8V(Max.), Vih = 2.0V(Min.)• Same electrical characteristic and high speed operation as 74VHC series• Low consumption current: Idd=1.0μA(Max.)(Top=25°C)• Wide power voltage range: 2.0V to 5.5V
• Wide input voltage range: Vih=5.5V(Max.)(Vdd=0 to 5.5V)• High speed: Tpd=3ns(Typ.)(Vdd=5.0V)• Small package: SOT-25, SC-70-5(SOT-353)• 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 (Input tolerant)■Selection guide
