DESCRIPTION
CD40109B 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 high-voltage output signal (E, F, G, H) with
logical 1 = VDD and logical 0 = VSS.
The RCA-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 0.7 VCC; VCC may
exceed VDD, and input signals may exceed VCC and VDD. When operated in the mode VCC > VDD, the CD40109
will operate as a high-to-low level-shifter.
The CD40109 also features individual three-state output capability. A low level on any of the separately enabled
three-state output controls produces a high-impedance state in the corresponding output.

This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more
susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.
