HCF4055B is a single digit BCD to 7 segment

decoder driver circuit that provides a level shifting

function on the chip. This feature permits the BCD

input-signals swings (V

to V ) to be the same

I = 100nA (MAX) AT V = 18V T = 25°C

as or different from the 7-segment output signal

swings (V to V ). For example, the BCD

MEETS ALL REQUIREMENTS OF JEDEC

DEVICES"

input-signal swings (V to V ) may be as low as

DD SS

0 to -3V, whereas the output-display drive signal

swing (V to V ) may be from 0 to -5V. If V to

exceeds 15V, V

to V should be at least

DD SS

4V. The 7 segment outputs are controlled by the

DISPLAY-FREQUENCY (DF) input, which causes

the selected segment outputs to be low, high, or a

square wave output (for liquid crystal displays).

DESCRIPTION

HCF4055B is a monolithic integrated circuit

fabricated in Metal Oxide Semiconductor

technology available in DIP and SOP packages.
