recommended for high-side switching applications that benefit from separate logic and load grounds, these devices encompass load supply voltages to 80 v and output currents to -500 ma. these 8-channel source drivers are useful for interfacing between low-level logic and high-current loads. typical loads include relays, solenoids, lamps, stepper and/or servo motors, print hammers, and leds. all devices may be used with 5 v logic systems ?ttl, schottky ttl, dtl, and 5 v cmos. the udn2981a, udn2982a, udn2982lw, and a2982slw are electrically interchangeable, will withstand a maximum output off voltage of 50 v, and operate to a minimum of 5 v; the udn2983a, udn2984a, udn2984lw, and a2984slw drivers are electrically inter- changeable, will withstand an output voltage of 80 v, and operate to a minimum of 35 v. all devices in this series integrate input current limiting resistors and output transient suppression diodes, and are activated by an active high input. the suffix ??(all devices) indicates an 18-lead plastic dual in-line package with copper lead frame for optimum power dissipation. under normal operating conditions, these devices will sustain 120 ma continuously for each of the eight outputs at an ambient temperature of +50 c and a supply of 15 v. the suffix ?w?(udn2982lw and udn2984lw only) indicates an 18- lead surface-mountable wide-body soic package; the a2982slw and a2984slw are provided in a 20-lead wide-body soic package with im- proved thermal characteristics. the udn2982a, udn2982lw, a2982slw, udn2984a, udn2984lw, and a2984slw drivers are also available for operation over an extended temperature range to -40 c. to order, change the prefix ?dn to ?dq?or the suffix ?lw?to ?lw? features ttl, dtl, pmos, or cmos compatible inputs 500 ma output source current capability transient-protected outputs output breakdown voltage to 80 v dip or soic packaging 8-channel source drivers always order by complete part number, e.g., udn2981a . note that all devices are not available in all package styles. absolute maximum ratings at 25 c free-air temperature output voltage range, v ce (udn2981a, udn2982a, udn2982lw, and a2982slw) . . 5 v to 50 v (udn2983a, udn2984a, udn2984lw, and a2984slw) . 35 v to 80 v input voltage, v in (udn2981a and udn2983a) . . . . . . . . . 15 v (udn2982a, udn2984a, udn2982lw, udn2984lw, a2982slw, and a2984slw) . . . . . . . . . 20 v output current, i out . . . . . . . . . . . . . . -500 ma 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 data sheet 29310d* 1 2 3 4 5 6 7 8 v s gnd 11 12 13 14 15 16 17 18 udn2981a thru udn2984a dwg. no. a-10, 243 2981 thru 2984 note that the udn2980a series (dual in-line package) and udn2980lw series (small-outline ic package) are electrically identical and share a common terminal number assignment.
