The Allegro Microsystems A6818SEP is a 32-bit serial input latched source driver, suitable for driving vacuum-fluorescent displays and other peripheral power driver applications. It integrates a 32-bit CMOS shift register, data latches, and control circuitry with bipolar sourcing outputs and PNP active pull-downs.
Key electrical specifications include a 60V minimum output breakdown voltage and a maximum output current of 40mA. The device supports a high data-input rate of up to 33 MHz with a 3.3V or 5V logic supply, allowing direct interfacing with microprocessor-based systems. A controlled output slew rate is incorporated to reduce electromagnetic noise.
The A6818SEP is housed in a 44-pin PLCC package, designed for surface mounting. Its low-power CMOS logic and latches, combined with low output-saturation voltages, make it an efficient choice for multiplexed display driving. The device offers improved performance over older UCN/UCQ5818x series.
This driver is an improved replacement for parts like SN75518N, SN75518NF, UCN5818x, and UCQ5818x. Similar devices include the A6810 (10-bit) and A6812 (20-bit).
