DESCRIPTION
The HCC4504B and HCF4504B are monolithic in-
tegrated circuits, available in 16-lead dual-in-line
plastic or ceramic packages or in 16-pin SO micro-
packages.
The HCC4504B and HCF4504B are hex non-invert-
ing level shifters. They will shift a TTL signal to
CMOS logic levels for any CMOS supply voltage be-
tween 5V and 15V. A control input also allows inter-
face from CMOS to CMOS at one logic level to
another logic level. Either up or down level translat-
ing is accomplished by selection of power supply le-
vels V
DD
and V
CC
. The V
CC
level sets the input signal
levels ; V
DD
selects the output voltage levels.
The supply current is typically 1nA at V
DD
= 10V for
CMOS to CMOS operation. For TTL to CMOS trans-
lation the supply current is typically 2.5mA taken
from V
CC
