The UDN2596A and UDN2597A are 8-channel saturated sink driver ICs that provide low output saturation voltages at high load currents. 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 UDN2596A and UDN2597A are 8‑channel saturated sink driver ICs designed to interface low‑power digital logic with high‑current loads such as relays, solenoids, stepper motors, and LED displays. They feature low output‑saturation voltages, fast turn‑off, and are compatible with TTL, CMOS, and automotive logic levels.
The datasheet lists maximum output voltage of 50 V, output currents of 500 mA (2596) and 1 A (2597), saturation voltages of 0.5 V/1.0 V, and operating temperature range from –20 °C to +85 °C. Physical details include a 20‑pin DIP package and dimensions for board layout. A selection guide helps choose devices based on required current, voltage, and driver count.
