Product Information

6A259 ADVANCE INFORMATION (Subject to change without notice) March 22, 2000 8-BIT ADDRESSABLE DMOS POWER DRIVER The A6A259KA and A6A259KLB combine a 3-to-8 line CMOS decoder and accompanying data latches, control circuitry, and DMOS outputs in a multi-functional power driver capable of storing single-line data in the addressable latches or use as a decoder or demuliplexer. 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 pullup resistors to ensure an input logic high. Four modes of operation are selectable with the CLEAR and ENABLE inputs. The addressed DMOS output inverts the DATA input with all unaddressed outputs remaining in their previous states. All of the output drivers are disabled (the DMOS sink drivers turned off) with the CLEAR input low and the ENABLE input high. The A6A259KA/KLB DMOS open-drain outputs are capable of sinking up to 500 mA. The A6A259KA is furnished in a 20-pin dual in-line plastic package. The A6A259KLB is furnished in a 24-lead wide-body, smalloutline plastic batwing package (SOIC) with gull-wing leads for surfacemount 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 85°C.
