discontinued product shown for reference only. quad 1.5 a darlington switches high-voltage, high-current darlington arrays uln2064b/lb through uln2069b/lb are designed for interface between low-level logic and a variety of peripheral loads such as relays, solenoids, dc and stepper motors, magnetic print hammers, multiplexed led and incan- descent displays, heaters, and similar loads. output off voltage ratings of 50 v and 80 v are available. these quad drivers can drive resistive loads to 480 watts (1.5 a x 80 v, 26% duty cycle). for inductive loads, sustaining voltages of 35 v and 50 v at 100 ma are specified. quad drivers uln2064b/lb, uln2065b/lb, uln2068b/lb, and uln2069b/lb are intended for use with ttl, low-speed ttl, and 5 v mos logic. the uln2065b/lb and uln2069b/lb are selected for the 80 v minimum output breakdown specification. the uln2068b/lb and uln2069b/lb have pre-driver stages and are recommended for applications requiring high gain (low input-current loading). quad-driver arrays are supplied with heat-sink contact tabs in 16-pin plastic dlps (suffix ?? and 20-lead surface-mountable wide- body soics (suffix ?b?. features ttl, dtl, mos, cmos compatible inputs transient-protected outputs loads to 480 watts heat-sink contact tabs automotive capable absolute maximum ratings at +25 c free-air temperature for any one driver (unless otherwise noted) output voltage, v cex ................ see guide output sustaining voltage, v ce(sus) ............................. see guide output current, i out (note 1) .......... 1.75 a input voltage, v in ...................... see guide input current, i b (note 2) .................. 25 ma supply voltage, v s (uln2068b/lb & 2069b/lb) ... 10 v total package power dissipation, p d ....................................... see graph operating temperature range, t a ................................. -20 c to +85 c storage temperature range, t s ................................ -55 c to -150 c 1. allowable combinations of output current, number of outputs conducting, and duty cycle are shown on the following pages. 2. input current may be limited by maximum allowable input voltage. data sheet 29305h always order by complete part number, e.g., uln2068b . 2064 thru 2069 uln2064/65b k16 15 14 13 12 611 710 89 1 2 3 4 5 dwg. no. a-9765a b c k c b gnd gnd c nc b gnd gnd b nc c .com .com .com .com 4 .com u datasheet
