Understanding the A68064 Datasheet: A Guide to the DABIC-5 64-Bit Serial-Input Latched Sink Driver
If you are digging into the A68064 datasheet, you are likely working on a project that requires controlling a high volume of LEDs or thermal printhead elements. Manufactured by Allegro MicroSystems, the A68064 is a powerhouse in the world of large-scale peripheral power management. What is the A68064?
The A68064 is a 64-bit serial-input latched sink driver. In simpler terms, it acts as a bridge between low-power logic (like a microcontroller) and high-power loads. It uses Allegro’s proprietary DABIC-5 (Digital/Analog BiCMOS) process, which allows it to combine high-speed CMOS shift registers and latches with high-voltage bipolar output drivers on a single chip. Key Features and Specifications
When you open the datasheet, several critical parameters define the device’s performance:
64-Bit Capacity: It can control 64 individual outputs simultaneously. This is ideal for reducing the number of control lines needed in complex systems.
High-Voltage Outputs: The sink drivers are typically rated for up to 40V, allowing you to drive significant loads without damaging the chip.
Output Current: Each output is generally capable of sinking up to 100mA. Note that thermal limitations of the package usually prevent all 64 outputs from sinking 100mA at the same time.
High-Speed Operation: The CMOS shift registers can handle data clock rates up to 25 MHz, making it suitable for applications requiring fast refresh rates.
Serial-to-Parallel Conversion: It uses a standard serial data input. You clock in 64 bits of data, and upon a "Latch" signal, those bits are transferred to the outputs. Pinout and Connectivity
The A68064 typically comes in high-density packages like the TQFP (Thin Quad Flat Pack) to accommodate the 64 output pins plus power and control lines. Key pins to look for in the datasheet include: VDD: The logic supply voltage (usually 3.3V or 5V).
Clock (CLK): Shifts data into the internal register on the rising edge.
Serial Data In (SDI): The pin where you send your bitstream.
Serial Data Out (SDO): Used for "daisy-chaining" multiple A68064 chips together to control 128, 192, or more outputs.
Output Enable (OE): A global control that turns all outputs on or off regardless of the latched data. Out 0 to Out 63: The 64 open-collector sink outputs. Common Applications
Because of its high density, the A68064 is most commonly found in:
Thermal Printheads: Controlling the heating elements in receipt or label printers.
LED Video Displays: Driving large-scale signage where individual pixel control is necessary.
Industrial Automation: Acting as an interface for relays, solenoids, or small motors. Design Considerations
When designing with the A68064, pay close attention to the Power Dissipation section of the datasheet. While the chip can sink current on all 64 channels, the cumulative heat can be substantial. Engineers often use Pulse Width Modulation (PWM) on the Output Enable (OE) pin to control brightness or power consumption and stay within safe thermal limits.
The A68064 is a robust, efficient solution for high-density power switching. By consolidating 64 channels into a single serial-controlled package, it simplifies PCB layout and reduces the overhead on your MCU.
The A68064 is a component typically manufactured by Teccor (now part of Littelfuse) or NBR, and it is described across various technical sources as a high-performance MOSFET, thyristor, or NPN transistor depending on the specific sub-variant. It is most commonly housed in a TO-220 package and is designed for power control and switching.

High Speed: Designed for high-frequency applications, including switching power supplies and high-speed interface circuits.
