LINEAR INTEGRATED CIRCUITS
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
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 each Darlington pair, allowing operation directly with PMOS or
CMOS utilizing supply voltage of 6 to 15V.
In all cases, the individual Darlington pair collector current rating is 500 rnA. However, outputs may be
paralleled for higher load current capability. The devices are supplied in a 16-lead dual in-line plastic
package with copper frame.
