Use these substitutes if A68064 is unavailable: | Part | Manufacturer | Notes | |------|--------------|-------| | A6801 | Allegro | 8-bit latched sink driver, 50V, 350mA/ch | | A6841 | Allegro | Similar, possibly different output current | | TPIC6B595 | Texas Instruments | Logic-level replacement, 50V, 150mA | | MIC5841 | Micrel (Microchip) | 80V, 500mA, serial-in latched driver | : If you cannot source the original Teccor
Many assume the A68064 is pin-compatible with the ULN2803. It is . The A68064 has four channels (not eight), and the power ground (PGND) is separate from the logic ground (LGND). The datasheet’s pin diagram is essential to avoid shorting high-current returns into sensitive logic circuits. Use these substitutes if A68064 is unavailable: |
