CMOS LOGIC IC
ELM7SU04B
Unbuffer Inverter
■General description
ELM7SU04B is CMOS unbuffer inverter IC. It realizes high speed operation similar to LS-TTL with lower
power consumption by CMOS features.
■Features
・ Same electrical characteristic as 74HC series (output current is around 1/2 of 74HC series)
・ Low consumption current
: Idd=1.0μA(Max.)(Top=25℃ )
・ Wide power voltage range
: 2.0V~6.0V
・ High speed
: Tpd=5ns(Typ.)(Vdd=5.0V)
・ Symmetrical output impedance : | Ioh |=Iol=2mA (Min.)(Vdd=4.5V)
・ Small package
: SOT-25
■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

* 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
