UDN2944 QUAD HIGH-CURRENT / HIGH-VOLTAGE SOURCE DRIVER

2944 QUAD HIGH-CURRENT, HIGH-VOLTAGE SOURCE DRIVER Capable of driving loads to 4 A at supply voltages to 60 V (inductive loads to 35 V), the UDN2944W is a quad high-current, highvoltage source driver. Each of the four power drivers can provide space- and cost-saving interface between low-level signal-processing circuits and high-power loads in harsh environ.
