MC34156
28-Channel Inkjet Driver
The MC34156 is a 28–Channel 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 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). The ac electrical characteristics of the drivers are tightly controlled and thereby the energy of the device delivers to the inkjet print head.
