Caution: These CMOS devices have input static protection (Class 3) but are still susceptible to damage if exposed to extremely high static electrical charges. The A6B273KA and A6B273KLW 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 A6B273KA/KLW DMOS open-drain outputs are capable of sinking up to 500 mA. Similar devices with reduced rDS(on) are available as the A6273KA/KLW. The A6B273KA is furnished in a 20-pin dual in-line plastic package. The A6B273KLW is furnished in a 20-lead wide-body, small-outline plastic 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.

Some variants cited in this footnote are in production but have been determined to be LAST TIME BUY or NOT FOR NEW DESIGN. This classification indicates that sale of this device is currently restricted to existing customer applications. The variants should not be purchased for new design applications because obsolescence in the near future is probable. Samples are no longer available. Status change for LAST TIME BUY: October 31, 2006. Deadline for receipt of LAST TIME BUY orders: April 27, 2007. These variants include: A6B273KLW and A6B273KLWTR. Status change for NOT FOR NEW DESIGN: May 1, 2006. These variants include: A6B273KA. 6B273 8-BIT LATCHED DMOS POWER DRIVER ALLOWABLE PACKAGE POWER DISSIPATION IN WATTS LOGIC SYMBOL 2.5 1 R 11 C1 2.0 SU FF IX 1.5 'A ', R θJ A = SU FF IX 'LW ', R 1.0 55 °C /W θJA = 90 °C /W 0.5 0 25 50 75 100 125 AMBIENT TEMPERATURE IN ° C 150 2 1D 4 3 1D 5 8 1D 6 9 1D 7 12 1D 14 13 1D 15 18 1D 16 19 1D 17 Dwg.
