8-BIT LATCHED DMOS POWER DRIVER

The A6273KA and A6273KLW combine eight positive-edgetriggered D-type data latches and DMOS outputs for systems requiring relatively high load power. Driver applications include relays, solenoids, and other medium-current or high-voltage peripheral power loads. The CMOS inputs and latches allow direct interfacing with microprocessor-based systems. Use with TTL may require appropriate pull-up resistors to ensure an input logic high.

The DMOS output inverts the DATA input. All of the output drivers are disabled the DMOS sink drivers turned OFF with the CLEAR input low. The A6273KA/KLW DMOS open-drain outputs are capable of sinking up to 750 mA.

The A6273KA is furnished in a 20-pin dual in-line plastic package.
