1 / 8 page TL5812, TL5812l VACUUM FLUORESCENT DISPLAY DRIVERS SLDS011B − OCTOBER 1985 − REVISED MAY 1993 1 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 POST OFFICE BOX 1443 • HOUSTON, TEXAS 77251−1443 D Drives up to 20 Lines D 70-V Output Voltage Swing Capability D 40-mA Output Source Current Capability D High-Speed Serially-Shifted Data Input D CMOS-Compatible Inputs D Direct Replacement for Sprague UCN5812A description The TL5812 and TL5812I are monolithic BIDFET† integrated circuits designed to drive a dot matrix or segmented vacuum fluorescent display (VFD). Each device features a serial data output to cascade additional devices for large display arrays. A 20-bit data word is serially loaded into the shift register on the low-to-high transition of CLOCK. Parallel data is transferred to the output buffers through a 20-bit D-type latch while LATCH ENABLE is high and is latched when LATCH ENABLE is low. When BLANKING is high, all outputs are low. The outputs are totem-pole structures formed by npn emitter-follower and double-diffused MOS (DMOS) transistors with output voltage ratings of 70 V and a source-current capability of 40 mA. All inputs are CMOS compatible. The TL5812 is characterized for operation from 0 °C to 70°C. The TL5812I is characterized for operation from − 40 °C to 85°C. † BIDFET − Bipolar, double-diffused, N-channel and P-channel MOS transistors on same chip. This is a patented process.
