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
Acting as an interface for relays, solenoids, or small motors. Design Considerations a68064 datasheet
Often grouped with A68063 , A68066 , and A68067 as part of a compatible series for industrial repairs
Controlling the heating elements in receipt or label printers.
The A68064 is typically housed in a standard 16-pin Dual In-line Package (DIP) or a Small Outline Integrated Circuit (SOIC) package. Below is a breakdown of the standard pinout functions. Common Applications Acting as an interface for relays,
Design Note: This voltage drop generates localized heat, which must be accounted for in your thermal management budget. Output Leakage Current ( ICEXcap I sub cap C cap E cap X end-sub
Asynchronous input that immediately clears all internal latches, turning off all four output channels instantly.
The A68064 is classified within the discrete semiconductor family. Depending on the application lifecycle and vintage, it functions reliably as a high-reliability switch or N-channel MOSFET designed to substitute complex Darlington arrays. The primary architecture optimizes power path efficiency by enforcing low internal resistance ( Below is a breakdown of the standard pinout functions
Robust design engineered for high-power applications. 2. A68064 Pinout and Functional Description
Below is a simple Arduino sketch demonstrating how to control 8 outputs using three digital pins, as implied by the datasheet’s serial interface:
Because the tab is frequently tied to Pin 2, a mica or polyimide insulating washer must be placed between the tab and the heat sink if the heat sink is grounded to the chassis. Equivalents and Substitutes
The A68064 typically comes in high-density packages like the 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).
