MOTOROLA ANALOG IC DEVICE DATA
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
• Addressable Data Entry
• Tightly Controlled AC and Electrical Characteristics for Inkjet Printers
• CMOS, TTL Compatible Inputs
• Low Power CMOS Logic

NOTES:
1. DATUMS –L–, –M–, AND –N– ARE DETERMINED WHERE TOP OF LEAD
SHOULDER EXITS PLASTIC BODY AT MOLD PARTING LINE.
2. DIMENSION G1, TRUE POSITION TO BE MEASURED AT DATUM –T–,
SEATING PLANE.
3. DIMENSIONS R AND U DO NOT INCLUDE MOLD FLASH. ALLOWABLE MOLD
FLASH IS 0.010 (0.25) PER SIDE.
4. DIMENSIONING AND TOLERANCING PER ANSI Y14.5M, 1982.
5. CONTROLLING DIMENSION: INCH.
6. THE PACKAGE TOP MAY BE SMALLER THAN THE PACKAGE BOTTOM BY
UP TO 0.012 (0.300). DIMENSIONS R AND U ARE DETERMINED AT THE
OUTERMOST EXTREMES OF THE PLASTIC BODY EXCLUSIVE OF MOLD
FLASH, TIE BAR BURRS, GATE BURRS AND INTERLEAD FLASH, BUT
INCLUDING ANY MISMATCH BETWEEN THE TOP AND BOTTOM OF THE
PLASTIC BODY.
7. DIMENSION H DOES NOT INCLUDE DAMBAR PROTRUSION OR
INTRUSION. THE DAMBAR PROTRUSION(S) SHALL NOT CAUSE THE H
DIMENSION TO BE GREATER THAN 0.037 (0.940). THE DAMBAR
INTRUSION(S) SHALL NOT CAUSE THE H DIMENSION TO BE SMALLER
THAN 0.025 (0.635).
