Description

Low output-saturation voltages at high load currents are provided by UDN2596A and UDN2597A sink driver ICs.  UDN2596A and UDN2597A 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 saturated 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.

The saturated (non-Darlington) NPN outputs provide low collectoremitter voltage drops as well as improved turn-off times due to an active pull-down function within the output predrive section. The  UDN2596A and UDN2597A  is for use with output loads to 500 mA or 1 A. Adjacent outputs may be paralleled for higher load currents.

Inputs require very low input current and are activated by a low logic level consistent with the much greater sinking capability associated with NMOS, CMOS, and TTL logic. The UDN2596A and UDN2597A are rated for use with 5 V logic levels.

Both devices are furnished in 20-pin DIP packages with copper leadframes for improved thermal characteristics. The  UDN2596A and UDN2597A are also available for operation between -40 and +85. To order, change the prefix from 'UDN' to 'UDQ'.
