SCHS099B – Revised January 2003
The CD40109, 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
signals. There are no restrictions on the
sequence of application of V
DD
, V
CC
, or the
input signals. In addition, with one
exception there are no restrictions on the
relative magnitudes of the supply voltages
or input signals within the device maximum
ratings, provided that the input signal
swings between V
SS
and at least 0.7 V
CC
;
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 CD40109 will operate
as a high-to-low level-shifter.
The CD40109B-Series types are supplied in
16-lead ceramic dual-in-line packages
(F3A suffix), 16-lead dual-in-line plastic
packages (E suffix), 16-lead small-outline
packages (NSR suffix), and 16-lead thin shrink
small-outline packages (PW and PWR suffixes).
