TC4055BP, TC4056BP/BF are LC drivers which drive the

field effect type liquid crystal with seven segments

by BCD input.

If DF input-L, a selected output among segment

outputs of a through g becomes H level and if DF

input=H, a selected output becomes L level.

Seven segment liquid crystal element can be directly

driven by applying the pulse in-phase with DF input

to the common terminal (back plane) of liquid crystal.

TC4055BP is equipped with DF output for the common.

terminal and TC4056BP/BF is equipped with the latch.

If VEE

lowers only L side of logical signal can be

achieved.
