HIGH SPEED CMOS LOGIC IC ELM7SH126xA ■General description ELM7SH126xA is bus buffer with 3-STATE output, 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°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=3.8ns(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 ■Selection guide ELM7SH126xA-EL Symbol a Function b Package c d Product version Taping direction 126: Bus buffer M: SOT-25 T : SC-70-5(SOT-353) A EL: Refer to PKG file ELM7SH 126 x A - EL ↑ ↑ ↑ ↑ a b c d ■Maximum absolute ratings Parameter Power supply voltage Input voltage Output voltage Input protection diode current Output parasitic diode current Output current VDD/GND current Power dissipation Storage temperature Symbol Vdd Vin Vout Iik Iok Iout Idd, Ignd Pd Tstg Limit -0.5 to +6.0 -0.5 to +6.0 -0.5 to Vdd+0.5 -20 ±20 ±25 ±50 150 -65 to +150 4- 1 Unit V V V mA mA mA mA mW °C HIGH SPEED CMOS LOGIC IC ELM7SH126xA ■Suggested operating condition Parameter Power voltage Input voltage Output voltage Operating temperature Symbol Vdd Vin Vout Top High-input down-time tr, tf Limit 2.0 to 5.5 0 to 5.5 0 to Vdd -40 to +85 Vdd=3.3±0.3V Vdd=5.0±0.5V ■Pin configuration 1 Pin No. 1 2 3 4 5 4 2 0 to 200 0 to 100 ns ■Truth Table TOP VIEW 5 Unit V V V °C 3 Pin name OE INY GND OUTX VDD OE High High Low Low Input Output OUTX High Low Hi-Z Hi-Z INY High Low High Low ■DC electrical characteristics Parameter Sym.
