A68064 Datasheet May 2026

The A68064 operates as a simple SPI-like device without a dedicated chip select (instead using Output Enable). Here’s the standard workflow:

Below is a simple Arduino sketch demonstrating how to control 8 outputs using three digital pins, as implied by the datasheet’s serial interface:

// A68064 Driver Example
int dataPin = 2;
int clockPin = 3;
int strobePin = 4;
int enablePin = 5;
void setup() 
pinMode(dataPin, OUTPUT);
pinMode(clockPin, OUTPUT);
pinMode(strobePin, OUTPUT);
pinMode(enablePin, OUTPUT);
digitalWrite(enablePin, LOW); // Enable outputs
digitalWrite(strobePin, LOW);

void writeA68064(byte data) 
// Shift out 8 bits, MSB first (output 1 = MSB)
for (int i = 7; i >= 0; i--) 
digitalWrite(dataPin, (data >> i) & 1);
digitalWrite(clockPin, HIGH);
delayMicroseconds(1);
digitalWrite(clockPin, LOW);
// Latch the data
digitalWrite(strobePin, HIGH);
delayMicroseconds(1);
digitalWrite(strobePin, LOW);

void loop() 
writeA68064(0b10101010); // Alternate outputs ON
delay(1000);
writeA68064(0b01010101); // Alternate outputs OFF
delay(1000);

Before diving into pinouts and timing diagrams, let’s highlight the core features that make the A68064 a go-to component for interface applications:

These features make the A68064 ideal for driving multiple loads with minimal microcontroller pins. a68064 datasheet

Where to get the official datasheet

If this generic reference is sufficient, tell me which sections you want expanded (pin tables, timing diagrams, example schematics, register map). If you meant a specific manufacturer's A68064, provide the maker or allow me to search and I will fetch the official datasheet.

The A68064 is a high-performance N-channel MOSFET or thyristor (depending on the specific manufacturer variant) commonly manufactured by Teccor (now part of Littelfuse). It is primarily designed for power switching, motor control, and industrial automation applications. Key Technical Specifications

The A68064 is typically housed in a TO-220 package, which is favored for its mechanical robustness and ability to dissipate heat through an attached heat sink. The A68064 operates as a simple SPI-like device

Voltage Rating: Often rated up to 800V, making it suitable for high-voltage power management. Current Rating: Capable of handling up to 10 Amps.

Operating Temperature: Specified for an extended range of -40°C to 105°C.

Power Dissipation: Typically handles about 2 Watts of power.

Gate Trigger Voltage: Standardized at approximately 1.4V for thyristor versions. A68064 Teccor - Xecor

The A68064 is a microprocessor chip developed by MOS Technology, Inc., and used in various computer systems, notably the Commodore 64, which is one of the most popular home computers of the 1980s. Here are key points from its datasheet:

A frequently overlooked section of the a68064 datasheet is thermal design. The device dissipates power primarily through output transistor saturation:

PD = ∑ (VCE(sat) × IOUT(n)) + (VDD × IDD)

For example, with 8 outputs at 250 mA each and VCE(sat) = 0.9V: PD = 8 × (0.9 × 0.25) + (5 × 0.01) ≈ 1.8 W void writeA68064(byte data) // Shift out 8 bits,

In a DIP package with θJA = 65°C/W, the junction temperature rise is 117°C above ambient—exceeding the limit. Thus, you must:

The 50V rating and 500 mA capability suit most small industrial relays. Note: Place additional freewheeling diodes close to the relay coil to minimize EMI. The internal COM clamp diode works but external Schottky diodes improve switching speed.
