DESCRIPTION
HCF4054B is a monolithic integrated circuit
fabricated in Metal Oxide Semiconductor
technology available in DIP and SOP packages.
HCF4054B provides level shifting similar to
HCF4055B and HCF4056B, independently
strobed latches, and common DF control on 4
signal lines. This device is intended to provide
drive signal compatibility with HCF4055B and
HCF4056B 7-segment decoder types for the
decimal point, colon, polarity, and similar display
lines. A level-shifted high amplitude DF output can
be obtained from any HCF4054B output line by
connecting the corresponding input and strobe
lines to a low and high levels. HCF4054B may
also be utilized for logic level "up conversion" or
"down conversion" respectively. For example,
input signal swings (V
DD
to V
SS
) from +5V to 0V

can be converted to output signal swings (V
DD
to
V
EE
) of +5V to -5V. The level shifted function
permits the use of different input and output signal
swings. The input swings from a low level of V
SS
to a high level of V
DD,
while the outputs swings
from a low level of V
EE
to the same high level of
V
DD
. Thus, the input and output swings can be
selected independently of each other over a 3 to
18V range. V
SS
may be connected to V
EE
when
no level-shift function is required. Data is
transferred from input to output by placing a high
voltage level at the strobe input. A low voltage
level at the strobe input latches the data input and
the corresponding output segments remain
selected (or non selected) while the strobe is low.
