The HCC40109B (extended temperature range)
and HCF40109B (intermediate temperature range)
are monolithic integrated circuits, available in 16-
lead dual in-line plastic or ceramic package and
plastic micropackage. The HCC/HCF40109B con-
tains four low-to-high-voltage level-shifting circuits.
Each circuitwill shift a low-voltage digital-logic input
signal(A, B, C, D) with logical 1 =VCC and logical 0
=V
SS toa higher-voltage output signal (E, F, G, H)
with logical 1 = VDD and logical 0 = VSS. The
HCC/HCF40109B, unlike other low-to-high level-
shiftingcircuits,does notrequire thepresence ofthe
high-voltage supply (VDD) before the application of
eitherthe low-voltage supply (VCC)or the input sig-
nals. There are no restrictions on the sequence of
application of VDD,V
CC, or the input signals. In ad-
dition, there are no restrictions on the relative mag-
nitudesodthesupplyvoltagesorinput signals within
the device maximum ratings ;VCC mayexceedVDD,
and input signals may exceed VCC, andVDD. When
operated in the mode VCC VDD, the
HCC/HCF40109B, will operate as a high-to-low
level-shifter. The HCC/HCF 40109B also features
individual three-state output capability. A low level
