by UDN2596A and UDN2597A sink driver ICs. These devices can be

used as interface buffers between standard low-power digital logic

(particularly MOS) and high-power loads such as relays, solenoids,

stepping motors, and LED or incandescent displays. The eight satu-

rated sink drivers in each device feature high-voltage, high-current

open-collector outputs. Transient suppression clamp diodes and a

minimum 35 V output sustaining voltage allow their use with many

inductive loads.

emitter voltage drops as well as improved turn-off times due to an

active pull-down function within the output predrive section. The

UDN2596A is for use with output loads to 500 mA while the

UDN2597A is for use with loads to 1 A. Adjacent outputs may be

paralleled for higher load currents.

logic level consistent with the much greater sinking capability associ-

ated with NMOS, CMOS, and TTL logic. The UDN2596A and

UDN2597A are rated for use with 5 V logic levels.

leadframes for improved thermal characteristics. The UDN2596A is

also available for operation between -40 C and +85 C. To order,

change the prefix from ‘UDN’ to ‘UDQ’.
