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
