INTRODUCTION
MagTek’s Shift-Out IntelliHead consists of a high-performance multi-channel fully integrated
magnetic stripe decoder chip encapsulated within a low-profile magnetic read-head. This innovative,
yet low-cost card reading solution offers many important advantages over the conventional less-
integrated approach. The fully integrated Shift-Out IntelliHead is recommended for optimal
performance; however, the Triple Track Delta ASIC (Application Specific Integrated Circuit)
embedded in MagTek’s Shift-Out IntelliHead is available separately in a 14 pin MLF
TM
(MicroLeadFrame TM ) package for those applications dictating the use of a particular separate
magnetic head. Refer to MagTek specification 99875337 (for the 3V part) or 99875336 (for the old
5V unit).
Two other variations on the Shift-Out IntelliHead are also offered:

The Low-Power Shift-Out IntelliHead (21030028 & 21030036) is designed for battery
operated devices that need to “wake from swipe.” It features a typical quiescent current when
armed to accept a swipe of only 1.5 μA. See MagTek specification 99875349 for details.

The 5V-to-3V Shift-Out IntelliHead (21030027) is designed to allow the customer to take
advantage of some of the cost savings of the newer 3V Delta ASIC in most 5V systems. It
features a built-in regulator that accepts a supply voltage of 5V ±5%. See MagTek
specification 99875350 for details.
FEATURES
• Low cost solution for single, dual, or triple track readers – available in dual and triple-track
models
• Ultra-compact design – low-profile read head contains all needed circuits. Save PCB space!
• No external components – even the decoupling capacitor is integrated. Only 4 signals, VDD,
VSS, DATA, and STROBE to connect to your micro-controller for up to 3 tracks
• Data buffer with Shift-Out – allows full card data to be locally stored on ASIC. Use a low-cost
controller with no interrupts, limited memory, low-speed, low pin-count, etc.
• High noise immunity – no analog signals leave the shielded magnetic head! Withstands noisy PC
monitors, cell phones, switching power supplies, etc.
• High performance decoding – new design reads badly damaged cards; compensates for poor
head mounting
• Low voltage operation – 2.7 V to 3.6 V (2.8 V to 5.5 V for 5V units)*
• Low operating current – less than 1 mA maximum total current at 3.3V (for up to 3 tracks) while
card is being swiped (less than 4 mA for 5V units)*
• Ultra-low Sleep current – less than 120 μA maximum total current when no card is being swiped
