description

The TL4810B and TL4810BI are monolithic

dot matrix or segmented vacuum fluorescent

display (VFD). These devices feature a serial data

output to cascade additional devices for large

display arrays.

A 10-bit data word is serially loaded into the shift

register on the positive-going transitions of the

clock. Parallel data is transferred to the output

buffers through a 10-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.

Outputs are totem-pole structures formed by npn

emitter-follower

and

double-diffused

MOS

(DMOS) transistors with output voltage ratings of

70 V and 40-mA source-current capability. All

inputs are compatible with CMOS and TTL levels,

but each requires the addition of a pullup resistor

The TL4810B is characterized for operation from

0

°C to 70°C. The TL4810BI 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.
