Features, Applications

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 to 750 mA. The A6273KA is furnished a 20-pin dual in-line plastic package. The A6273KLW is furnished a 20-lead wide-body, small-outline plastic package (SOIC) with gull-wing leads for surface-mount applications. Copper lead frames, reduced supply current requirements, and low on-state resistance allow both devices to sink 150 mA from all outputs continuously, to ambient temperatures over 85C.

Note that the A6273KA (DIP) and the A6273KLW (SOIC) are electrically identical and share a common terminal number assignment.
