CD40109BNSR

Транслятор уровня напряжения, 4 входа, 6.8мА, 180нс, 3В до 18В, SOP-16.

The CD40109BNSR is a quad CMOS low-to-high Voltage Level Shifter 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. The CD40109, 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. 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.
