CMOS LOGIC IC ELM7S14B Schmitt Inverter
â General description
http://www.elm-tech.com
ELM7S14B is CMOS schmitt inverter IC. It realizes high speed operation similar to LS-TTL with lower power
consumption by CMOS features. The inner circuit structure of 3-stage logic gate obtains wider noise immunity
and constant output.
â Features
⢠Same electrical characteristic as 74HC series (output current is around 1/2 of 74HC series)
⢠Low voltage operation
: Idd=1.0μA(Max.)(Top=25°C)
⢠Wide power voltage range
: 2.0V to 6.0V
⢠High speed
: Tpd=5ns(Typ.)(Vdd=5.0V)
⢠Symmetrical output impedance : | Ioh |=Iol=2mA(Min.)(Vdd=4.5V)
⢠Small package
: SOT-25
â 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
