Overview
2596 AND 2597 8-CHANNEL SATURATED SINK DRIVERS 2596 AND 2597 8-CHANNEL SATURATED SINK DRIVERS Low output-saturation voltages at high load currents are provided 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 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 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.
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.

No.
W-100 Both devices are furnished in 20-pin DIP packages with copper 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’.
