AN0332 8 n-channel latchable power mosfet array ordering information general description the supertex AN0332 is an 8 n-channel 320v common source power mosfet array with a cmos 8 bit addressable latch. the outputs are guaranteed to have very low leakage current. the outputs are addressed by logic inputs a0, a1, and a2. the addressed and unaddressed output can be turned on or off by the data, reset, and write disable inputs. the AN0332 is ideally suited for low leakage/high impedance measurements, providing excellent accuracy as well as resolution for automatic bare board test equipment and other applications. features low drain to source leakage interfaces directly to ttl and cmos logic 8 independent channels low crosstalk between channels low power dissipation freedom from secondary breakdown serial data input on-chip decoder, latch with reset and write disable circuitry absolute maximum ratings 1 output voltage, v dd 320v logic supply voltage, v dd -0.5v to +15v logic input levels, all inputs -0.5v to v dd operating and storage temperature range -55 c to +150 c soldering temperature 2 300 c channel-to-channel crosstalk 10mv/v notes: 1. all voltages are referenced to v ss . 2. distance of 1.6mm from case for 10 seconds. applications high impedance/low leakage measurements for bare board testers high voltage piezoelectric transducer drivers high voltage electroluminescent panel drivers high voltage electrostatic array drivers general multi-channel driver arrays pin configuration q 7 v dd reset q 6 data q 5 w rite dis q 4 a 0 q 3 a 1 q 2 a 2 q 1 v ss q 0 note: see package outline section for dimensions. so-16 1 8 top view 2 3 4 5 6 7 16 9 15 14 13 12 11 10 C obsolete C
