SED2020FOA/OB

CMOS VFD DRIVER

■ DESCRIPTION

The SED2020FOA/OB is a CMOS LSI dot-matrix vacuum fluorescent display anode and grid driver. Ithas

20 high-voltage anode outputs in 2 × 10 blocks.

The SED2020FOA/OB is TTL, LSTTL, CMOS and HSCMOS compatible, allowing direct interface to a wide

range of standard devices. It has independent serial inputs and outputs for each 10-element block which

feature data transfer rates of up to 4 Mbits/s. All inputs have internal pull-ups and serial outputs have a

minimum fanout of one standard TTL load. The serial data transfer system simplifies controller requirements.

The SED2020FOA/OB can also be configured for 4-bit parallel data transfer.

SED2020FOA/OB uses a 5V logic supply and a 30 to 70V display supply, and is available in 44- or 46-pin

plastic flatpacks.
