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 (VDD to VSS) from +5V to 0V

HCF4054B
can be converted to output signal swings (VDD to
VEE) 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 VSS
to a high level of VDD, while the outputs swings
from a low level of VEE to the same high level of
VDD . Thus, the input and output swings can be
selected independently of each other over a 3 to
18V range. VSS 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.
