the mc34156 is a 28channel decoder/driver intended to be used in inkjet printer applications. by using sophisticated smartmos ? technology, it has been possible to combine low power cmos inputs and logic and high current, high voltage bipolar outputs capable of sustaining a maximum of 30 v. a 4to14 line decoder determines the selected output driver (n) in each 14driver bank. two independent output enable inputs (active low) then provide the final decoding to activate 1 or 2of28 outputs (out an and/or out bn ). the ac electrical characteristics of the drivers are tightly controlled and thereby the energy of the device delivers to the inkjet print head. 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 70 c. all driver outputs are capable of withstanding a contact discharge of 8.0 kv with the ic biased. ? esd output protection with clamping diodes ? addressable data entry ? tightly controlled ac and electrical characteristics for inkjet printers ? cmos, ttl compatible inputs ? low power cmos logic smartmos is a trademark of motorola, inc. ordering information device operating temperature range package MC34156FN t a = 0 to +70 c plastic package simplified block diagram outb1 outa0 outb2 outa1 outb3 outa2 outb4 outa3 outb5 outa4 outb6 outa5 outb7 outa6 outb8 outa7 outb9 outa8 gnd outa9 n/c gnd 7 8 9 10 11 12 13 14 15 16 17 39 38 37 36 35 34 33 32 31 30 29 6 5 4 3 2 1 44 43 42 41 40 18 19 20 21 22 23 24 25 26 27 28 outb0 n/c chip enable output enable b gnd logic supply ind (msb) inc inb gnd ina (lsb) output enable a n/c outb10 outb11 outb12 outb13 outa13 outa12 outa11 outa10 com output driver bank b 4to14 line decoder output driver bank a v dd this document contains information on a product under development. motorola reserves the right to change or discontinue this product without notice. ? motorola, inc. 1996 issue 0
