1 8-Channel Darlington Drivers FEATURES Improved Replacement for ULN80. Fast Turn-on and Turn-off. TTL/CMOS Compatible. APPLICATIONS Stepping Motor Driver. Relay Driver. LED Driver. Solenoid Driver. DESCRIPTION Manufactured with the standard bipolar process, the is a high-voltage, high-current 8- channel Darlington array, with each of the output transistors capable of sinking peak load current of 00mA and capable of withstanding at least 0 in the OFF state. The has a.7kω series base resistor to each Darlington pair and thus allows operation directly with TTL or CMOS logic circuitry operating at a supply voltage of. Outputs of the drivers can be paralleled for higher load current capability. These make the ideally suited for numerous interfaces between low-level logic circuitry and high-power peripheral loads, particularly those beyond the capabilities of standard logic buffers. Typical loads include relays, solenoids, stepping motors, heaters, multiplexed LED, and incandescent displays. The features open collector outputs and integral diodes for inductive load transient suppression.
