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
and V
. The V
level sets the input signal levels while V
selects the output voltage levels.

• 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
• and V
• Diode Protected Inputs to V
• 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*
