Intersil CD40109BMS
The CD40109BMS, unlike other low-to-high level shifting circuits, does not require the presence of the high voltage supply (VDD) before the application of either the low voltage supply (VCC) or the input signals. When operated in the mode VCC > VDD, the CD40109BMS will operate as a high-to-low level shifter. The CD40109BMS also features individual three-state output capability.| Part No. | CD40109BMS |

DESCRIPTION
CD40109BMS contains 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 = VCC and logical 0 = VSS to a higher voltage output signal (E, F, G, H) with logical 1 = VDD and logical 0 = VSS. There are no restrictions on the sequence of application of VDD, VCC, 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 VSS and at least 0.7VCC; VCC may exceed VDD, and input signals may exceed VCC and VDD. A low level on any of the separately enabled three-state output controls produces a high impedance state in the corresponding output. The CD40109BMS is supplied in these 16-lead outline packages: Braze Seal DIP Frit Seal DIP Ceramic Flatpack H4T H1E H6WFEATURES
