DESCRIPTION

These devices are analog multiplexer demultiplexers in high speed silicon gate C2MOS technology. These analog switches are bidirectional and digitally controlled. A built-in level shifting is included to allow them a control input range of up to ± 6V (peak) for an analog signal with digital control signal of 0 to 6V.

■ LOGIC LEVEL TRANSLATION TO ENABLE 5V LOGIC SIGNAL TO COMMUNICATE WITH ±5V ANALOG SIGNAL

■ WIDE OPERATING VOLTAGE RANGE (VCC - VEE) 2V TO 12V

■ LOW ”ON” RESISTANCE:

70Ω TYP. (VCC - VEE = 4.5 V)

50Ω TYP. (VCC - VEE = 9 V)

■ WIDE ANALOG INPUT VOLTAGE RANGE: ±6V

■ FAST SWITCHING

■ LOW CROSSTALK BETWEEN SWITCHES

■ HIGH ON/OFF OUTPUT VOLTAGE RATIO

■ LOW SINE WAVE DISTORTION: 0.02 (TYP.) AT VCC - VEE = 9 V

■ HIGH NOISE IMMUNITY VNIH = VNIL = 28 VCC (MIN.)

■ LOW POWER DISSIPATION ICC = 4 µA (MAX) AT TA = 25 °C
