Order this document from Analog Marketing 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. 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 • • • • 28–CHANNEL INKJET DRIVER (SMARTMOS Technology) SEMICONDUCTOR TECHNICAL DATA Addressable Data Entry 44 1 Tightly Controlled AC and Electrical Characteristics for Inkjet Printers FN SUFFIX PLASTIC PACKAGE CASE 777 CMOS, TTL Compatible Inputs Low Power CMOS Logic SMARTMOS is a trademark of Motorola, Inc.
