8-BIT ADDRESSABLE DMOS POWER DRIVER
A6259KA A6259KLW combine 3-to-8 line CMOS decoder accompanying data latches, control circuitry, DMOS outputs multi-functional power driver capable storing single-line data addressable latches decoder demuliplexer. Driver applications include relays, solenoids, other medium-current high-voltage peripheral power loads. CMOS inputs latches allow direct interfacing with microprocessor-based systems. with require appropriate pullup resistors ensure input logic high. Four modes operation selectable with CLEAR ENABLE inputs. addressed DMOS output inverts DATA input with unaddressed outputs remaining their previous states. output drivers disabled (the DMOS sink drivers turned off) with CLEAR input ENABLE input high. A6259KA/KLW DMOS open-drain outputs capable sinking Similar devices with reduced rDS(on) available A6A259. A6259KA furnished 20-pin dual in-line plastic package. A6259KLW furnished 20-lead wide-body, small-outline plastic package (SOIC) with gull-wing leads surface-mount applications. Copper lead frames, reduced supply current requirements, on-state resistance allow both devices sink from outputs continuously, ambient temperatures over 85°C.
