? 2002-2012 microchip technology inc. ds21417c-page 1 tc4403 features ? low quiescent current: 300 ? a max ? capacitive inputs with 300mv hysteresis ? both inputs must be driven to drive load ? low output leakage ? high peak current capability ? fast output rise time ? outputs individually testable applications ? isolated load drivers ?pulsers ? safety interlocks device selection table package type general description the tc4403 is a modified version of the tc4425 driver, intended to drive floating or isolated loads requiring high-current pulses. the load is intended to be con- nected between the outputs without other reference to supply or ground. then, only when both logic inputs and the v dd input are energized, is power supplied to the load. this construction allows the implementation of a wide variety of redundant input controllers. the low off-state output leakage and independence of the two half-circuits permit a wide variety of testing schemes to be utilized to assure functionality. the high peak current capability, short internal delays, and fast output rise and fall times ensure that sufficient power will be available to the load when it is needed. the ttl and cmos compatible inputs allow operation from a wide variety of input devices. the ability to swing the inputs negative without affecting device performance allows negative biases to be placed on the inputs for greater safety. in addition, the capacitive nature of the inputs allows the use of series resistors on the inputs for extra noise suppression. the tc4403 is built for outstanding ruggedness and reliability in harsh applications. input voltage excur- sions above the supply voltage or below ground are clamped internally without damaging the device. the output stages are power mosfets with high-speed body diodes to prevent damage to the driver from inductive kickbacks. part number package temp. range tc4403cpa 8-pin pdip 0c to +70c tc4403epa 8-pin pdip -40c to +85c tc4403mja 8-pin cerdip -55c to +125c 18 27 36 45 tc4403 out (gnd) in (gnd) gnd in (v dd ) v dd out (v dd ) nc nc 8-pin pdip/cerdip 1.5a high-speed, fl oating load driver
