ADDRESSABLE 28-LINE DECODER/DRIVER
Intended for use in ink-jet printer applications, the A5817SEP 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 1- 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 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 a 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 500 mA at ambient temperatures up to 85°C. The A5817SEP is furnished in a 44-lead plastic chip carrier (quad pack) for minimum-area, surface-mount applications.
