TYPICAL BIAS VOLTAGES

The ADDRESS (digtal-control inputs) and INHIBIT logic levels are : "0"=VSS and "1"=VDD. The analog signal (through the TG) may swing

from VEE to VDD

TYPICAL APPLICATIONS (TYPICAL TIME-DIVISION APPLICATION)

SPECIAL CONSIDERATIONS

Control of analog signals up to 20V peak to peak

can be achieved by digital signal amplitudes of 4.5

to 20V (if VDD -VSS =3V, aVDD -VEE of up to 13V

can be controlled; for VDD -VEE level differences

above 13V, a VDD -VSS of at least 4.5V is

required. For example, if VDD =+5, VSS =0, and

VEE = -13.5, analog signals from -13.5V to 4.5V

can be controlled by digital inputs of 0 to 4.5V. In

certain applications, the external load resistor

current may include both VDD and signal-line

components. To avoid drawing VDD current when

switch current flows into the transmission gate

inputs, the voltage drop across the bidirectional

switch must not exceed 0,8V (calculated from RON

values shown in DC SPECIFICATIONS). No VDD

current will flow through RL if the switch current

flows into leads 3 and 13.
