9 / 13 page 9 FN6261.0 May 19, 2006 Pin Descriptions ISL59446 (32 LD QFN) PIN NAME EQUIVALENT CIRCUIT DESCRIPTION 1 IN1A Circuit 1 Channel 1 input for output amplifier "A" 2, 4, 8, 13, 15, 24, 28, 30 NIC Not Internally Connected; it is recommended these pins be tied to ground to minimize crosstalk. 3 IN1B Circuit 1 Channel 1 input for output amplifier "B" 5 IN1C Circuit 1 Channel 1 input for output amplifier "C" 6 GNDB Circuit 4 Ground pin for output amplifier “B” 7 IN2A Circuit 1 Channel 2 input for output amplifier "A" 9 IN2B Circuit 1 Channel 2 input for output amplifier "B" 10 IN2C Circuit 1 Channel 2 input for output amplifier "C" 11 GNDC Circuit 4 Ground pin for output amplifier “C” 12 IN3A Circuit 1 Channel 3 input for output amplifier "A" 14 IN3B Circuit 1 Channel 3 input for output amplifier "B" 16 IN3C Circuit 1 Channel 3 input for output amplifier "C" 17 S1 Circuit 2 Channel selection pin MSB (binary logic code) 18 S0 Circuit 2 Channel selection pin. LSB (binary logic code) 19 OUTC Circuit 3 Output of amplifier “C” 20 OUTB Circuit 3 Output of amplifier “B” 21 V- Circuit 4 Negative power supply 22 OUTA Circuit 3 Output of amplifier “A” 23 V+ Circuit 4 Positive power supply 25 ENABLE Circuit 2 Device enable (active low). Internal pull-down resistor ensures device is active with no connection to this pin. A logic High puts device into power-down mode and only the logic circuitry is active. Logic states are preserved post power-down. 26 HIZ Circuit 2 Output disable (active high). Internal pull-down resistor ensures the device will be active with no connection to this pin. A logic high, puts the outputs in a high impedance state. Use this state to control logic when more than one MUX-amp share the same video output line. 27 IN0C Circuit 1 Channel 0 for output amplifier "C" 29 IN0B Circuit 1 Channel 0 for output amplifier "B" 31 IN0A Circuit 1 Channel 0 for output amplifier "A" 32 GNDA Circuit 4 Ground pin for output amplifier “A” IN V+ V- LOGIC PIN V+ V- GND 33k 21k + - 1.2V V+ V- OUT CIRCUIT 3 CIRCUIT 1 CIRCUIT 2 V- V+ GNDB CAPACITIVELY COUPLED ESD CLAMP GNDC GNDA CIRCUIT 4 V- THERMAL HEAT SINK PAD ~1M Ω SUBSTRATE ISL59446 |
