Designed to reduce logic supply current, chip size, and system cost, the A6833 integrated circuits offer high-speed operation for thermal print- ers.
The A6833 integrated circuit provides high‑speed serial‑input latched sink drivers for thermal printheads, multiplexed LED displays, and incandescent lamps. It combines bipolar Darlington outputs with low‑power CMOS logic, Schmitt‑trigger inputs, and a 32‑bit shift register, enabling operation with most microprocessor‑based systems.
The device is supplied in a 44‑lead plastic PLCC package, operates from a 3.3 V–5 V logic supply, and supports up to a 10 MHz data‑input rate. Typical applications include driving thermal printheads, LED display matrices, and low‑current lamp loads, with a peak output current of 125 mA per driver.
