ULN2429

The ULN2429 is a fluid detector.It is rated for operation with a load voltage of up to 30 volts,selected devices,for operation up to 50V are available as the ULN2924.In all other respects,it fluif detectors are identical.It is furnished in an improved 14-lead dual in-line plastic package with a copper alloy lead frame for superior thermal characteristics.However,in order to realize the maximum currenthandling capability of these devices,both of the output pins(1 and 14)and both ground pins(3 and 4)should be used.

Features of the ULN2429 are:(1)high output current;(2)AC or DC output;(3)single-wire probe;(4)low external parts count;(5)internal voltage regulator;(6)reverse voltage protection.

The absolute maximum ratings of the ULN2429 can be summarized as:(1)supply voltage,V_CC:continuous..-50V to +16V1hr.at +25°C...24V10s(2)output voltage,I_OUT:continuous..700mA1hr.at +25°C...1.0A;(3)package power dissipation,P_D:1.33W*;(4)operating temperature range,T_A:-40 to +85;(5)storage temperature range,T_S:-65 to +150.*derates at the rate of 16.67mW/ above T_A=+70.
