DESCRIPTION
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 circuit will shift a low-voltage digital-logic input
signal (A, B, C, D) with logical 1 = V
CC
and logical 0
= V
SS
to a higher-voltage output signal (E, F, G, H)
with logical 1 = V
DD
and logical 0 = V
SS
. The
HCC/HCF40109B,
unlike other low-to-high level-
shifting circuits, does not require the presence of the
high-voltage supply (V
DD
) before the application of
either the low-voltage supply (V
CC
) or the input sig-
nals. There are no restrictions on the sequence of
application of V
DD
, V
CC
, or the input signals. In ad-
dition, there are no restrictions on the relative mag-
nitudes od the supply voltages or input signals within
the device maximum ratings ; V
CC
may exceed V
DD
,
and input signals may exceed V
CC
, and V
DD
. When
operated in the mode V
CC
V
DD
, 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
