Features:

Operation of liquid crystals with CMOS

circuits provides ultra-low-pawer displays

Equivalent ac output drive for liquid-

crystal displays — no external capacitor required

= Voltage doubling across display, e.g.

VDD — VEE = 18 V results in effective

36 V pp drive across selected display

segments

Low- or high-output level de drive for

other types of displays

On-chip logic-level conversion for different

input- and output-level swings

Full decoding of all input combinations:

0-9, L, H, P, A~, and blank positions

Strobed-latch function—CD4054B Series

and CD40568 Series

DISPLAY-FREQUENCY (DF) output

for liquid-crystal common-line drive signal—
