Features, Applications

Intended for use in ink-jet printer applications, the A6817SEP addressable 28-line decoder/driver combines low-power CMOS inputs and logic with 28 high-current, high-voltage bipolar outputs. A 4-to-14 line decoder determines the selected output driver (n) in each 14-driver bank. Two independent output-enable inputs (active low) then provide the final decoding to activate or 2-of-28 outputs (OUTAn and/or OUTBn). Special internal circuitry is programmed at the time of manufacture to adjust the output pulse timing and thereby the energy the device delivers to the ink-jet print head. The DABiC-IV A6817SEP directly replaces the original BiMOS-II A5817SEP in most applications. The CMOS inputs cause minimal loading and are compatible with standard CMOS, PMOS, and NMOS logic. Use with TTL or DTL circuits may require appropriate pull-up resistors to ensure an input logic high. The internal CMOS logic operates from 5 V supply. A CHIP ENABLE function is provided to lock out the drivers during system power up. The 28 bipolar power outputs are open-collector 30 V Darlington drivers capable of sinking mA at ambient temperatures to 85C. The A6817SEP is furnished a 44-lead plastic chip carrier (quad pack) for minimum-area, surface-mount applications.
