datasheet 26180.110 A6800/a6801 dabic-5 latched sink drivers the A6800 and a6801 latched-input bimos ics merge high-current, high-voltage outputs with cmos logic. the cmos input section con- sists of 4 or 8 data (?d? type) latches with associated common clear, strobe, and output enable circuitry. the power outputs are bipolar npn darlingtons. this merged technology provides versatile, exible interface. these bimos power interface ics greatly bene t the simpli cation of computer or microprocessor i/o. the A6800 ics each contain four latched drivers. a6801 ics contain eight latched drivers. the cmos inputs are compatible with standard cmos circuits. ttl circuits may mandate the addition of input pull-up resistors. the bipolar darlington outputs are suitable for directly driving many peripheral/ power loads: relays, lamps, solenoids, small dc motors, etc. all devices have open-collector outputs and integral diodes for induc- tive load transient suppression. the output transistors are capable of sinking 600 ma and will withstand at least 50 v in the off state. because of limitations on package power dissipation, the simultaneous operation of all drivers at maximum rated current can only be accom- plished by a reduction in duty cycle. outputs may be paralleled for higher load current capability. the A6800sa is furnished in a standard 14-pin dip; the A6800sl and a6801slw in surface-mountable soics; the a6801sa in a 22-pin dip with 0.400? (10.16 mm) row centers; the a6801sep in a 28-lead plcc. these devices are lead (pb) free, with 100% matte tin plated leadframes. ? 3.3 v to 5 v l ogic supply range ? to 10 mhz data input rate ? high-voltage, high-current outputs ? darlington current-sink outputs, with improved low-saturation voltages use the following complete part numbers when ordering: ab so lute max i mum rat ings part number pins package A6800sa-t 14 dip A6800sl-t 14 soic a6801sa-t 22 dip a6801sep-t 28 plcc a6801slw-t 24 soic output voltage, v ce ............................................ 50 v supply voltage, v dd ............................................. 7 v input voltage range, v in .............. ?0.3 v to v dd +0.3 v continuous collector current, i c ........................ 600 ma package power dissipation, p d , see allowable power disspation chart, page 5 operating temperature range ambient temperature, t a ............ ?20c to +85c storage temperature, t s .......... ?55c to +150c caution: cmos devices have input-static protection, but are susceptible to damage when exposed to extremely high static-electrical charges. features ? relays ? lamps applications A6800sa a6801sep a6801slw a6801sa A6800sl ? cmos, ttl compatible inputs ? output transient protection ? internal pull-down resistors ? low-power cmos latches ? solenoids ? small dc motors ( datasheet : )
