MC14504B
Hex Level Shifter for TTL to
CMOS or CMOS to CMOS
The MC14504B is a hex non−inverting level shifter using CMOS
technology. The level shifter will shift a TTL signal to CMOS logic
levels for any CMOS supply voltage between 5 and 15 volts. A control
input also allows interface from CMOS to CMOS at one logic level to
another logic level: Either up or down level translating is
accomplished by selection of power supply levels V
DD
and V
CC
. The
V
CC
level sets the input signal levels while V
DD
selects the output
voltage levels.
Features
• UP Translates from a Low to a High Voltage or DOWN Translates
from a High to a Low Voltage
• Input Threshold Can Be Shifted for TTL Compatibility
• No Sequencing Required on Power Supplies or Inputs for Power Up
or Power Down
• 3 to 18 Vdc Operation for V
DD
and V
CC
• Diode Protected Inputs to V
SS
• Capable of Driving Two Low−Power TTL Loads or One Low−Power
Schottky TTL Load Over the Rated Temperature Range
• Pb−Free Packages are Available*

Maximum ratings are those values beyond which device damage can occur.
Maximum ratings applied to the device are individual stress limit values (not
normal operating conditions) and are not valid simultaneously. If these limits are
exceeded, device functional operation is not implied, damage may occur and
reliability may be affected.

This device contains protection circuitry to guard against damage due to high
static voltages or electric fields. However, precautions must be taken to avoid
applications of any voltage higher than maximum rated voltages to this
high−impedance circuit. For proper operation, V
in
and V
out
should be constrained
to the range V

Unused inputs must always be tied to an appropriate logic voltage level (e.g.,
either V
SS
or V
DD
). Unused outputs must be left open.
