8 / 12 page 8 FN6163.2 September 21, 2005 Pin Descriptions PIN NUMBER PIN NAME EQUIVALENT CIRCUIT DESCRIPTION 1, 3, 7 NIC Not Internally Connected; it is recommended this pin be tied to ground to minimize crosstalk 2 IN0 Circuit 1 Input for channel 0 4 IN1 Circuit 1 Input for channel 1 5 GND Circuit 4 Ground pin 6 IN2 Circuit 1 Input for channel 2 8 IN3 Circuit 1 Input for channel 3 9 S0 Circuit 2 Channel selection pin LSB (binary logic code) 10 S1 Circuit 2 Channel selection pin MSB (binary logic code) 11 V- Circuit 4 Negative power supply 12 V+ Circuit 4 Positive power supply 13 OUT Circuit 3 Output 14 IN- Circuit 1 Inverting input of output amplifier 15 HIZ Circuit 2 Output disable (active high); there are internal pull-down resistors, so the device will be active with no connection; “HI” puts the output in high impedance state 16 ENABLE Circuit 2 Device enable (active low); there are internal pull-down resistors, so the device will be active with no connection; "HI" puts device into power-down mode IN V+ V- CIRCUIT 1. LOGIC PIN V+ V- GND. 33K 21K + - 1.2V CIRCUIT 2. V+ V- OUT CIRCUIT 3. V- V+ CAPACITIVELY COUPLED ESD CLAMP GND CIRCUIT 4. AC Test Circuits FIGURE 24A. TEST CIRCUIT FOR MEASURING WITH A 50 Ω OR 75 Ω INPUT TERMINATED EQUIPMENT FIGURE 24B. BACKLOADED TEST CIRCUIT FOR VIDEO CABLE APPLICATION. BANDWIDTH AND LINEARITY FOR RL LESS THAN 500Ω WILL BE DEGRADED. NOTE: Figure 24A illustrates the optimum output load when connecting to input terminated equipment. Figure 24B illustrates backloaded test circuit for video cable applications.
