output-saturation voltages high load currents provided UDN2596A UDN2597A sink driver ICs. These devices used interface buffers between standard low-power digital logic (particularly MOS) high-power loads such relays, solenoids, stepping motors, incandescent displays. eight saturated sink drivers each device feature high-voltage, high-current open-collector outputs. Transient suppression clamp diodes minimum output sustaining voltage allow their with many inductive loads. saturated (non-Darlington) outputs provide collectoremitter voltage drops well improved turn-off times active pull-down function within output predrive section. UDN2596A with output loads while UDN2597A with loads Adjacent outputs paralleled higher load currents. Inputs require very input current activated logic level consistent with much greater sinking capability associated with NMOS, CMOS, logic. UDN2596A UDN2597A rated with logic levels.
