Always order by complete part number: a prefix to
indicate operating temperature range + the basic four-digit
part number + a suffix to indicate package style, e.g., UDK2559LB .

UDQ2559B, EB, and LB quad power drivers combine AND logic
gates and high-current bipolar outputs with complete output protection.
Each of the four outputs will sink 700 mA in the on state. The outputs
have a minimum breakdown voltage (load dump) of 60 V and a
sustaining voltage of 40 V. The inputs are compatible with TTL and
5 V CMOS logic systems.
these devices and is activated at approximately 1 A. It protects each
output from short circuits with supply voltages up to 25 V. When an
output current trip point is reached, that output stage is driven linearly
resulting in a reduced output current level. If an over-current or short-
circuit condition continues, the thermal-limiting circuits will first sense
the rise in junction temperature and then the rise in chip temperature,
further decreasing the output current. Under worst-case conditions,
these devices will tolerate short circuits on all outputs, simultaneously.

loads such as relays, solenoids, or dc stepping motors.

of batwing construction to provide for maximum package power
