L203

LINEAR INTEGRATED CIRCUITS I HIGH-VOLTAGE, HIGH-CURRENT 7 DARLINGTON ARRAYS These high-voltage, high-current Darlington transistor arrays comprise seven NPN Darlington pairs on a common monolithic substrate. All units feature open collector outputs and integral suppression diodes for inductive loads. Peak currents of 600 rnA can be withstood, making them ideal for driving tungsten filament lamps. The L 201 is a general-purpose array wich may be used with DTL, TTL, PMOS, CMOS, etc. It is pinned with inputs opposite outputs to facilitate circuit board layout and is priced to compete directly with discrete transistor alternatives. The L 202 was specifically designed for use with 14 to 25V PMOS devices. Each input has a Zener diode and resistor in series in order to limit the input current to a safe value. The L203 has a series base resistor to each Darlington pair allowing operation directly with TTL or CMOS operating at a supply voltage of 5V. The L204 has a series base resistor to ea...
