CD4070BC
Quad 2-Input EXCLUSIVE-OR Gate
General Description
The CD4070BC employs complementary MOS (CMOS)
transistors to achieve wide power supply operating range,
low power consumption, and high noise margin, the
CD4070BC provide basic functions used in the implemen-
tation of digital integrated circuit systems. The N- and P-
channel enhancement mode transistors provide a symmet-
rical circuit with output swing essentially equal to the supply
voltage. No DC power other than that caused by leakage
current is consumed during static condition. All inputs are
protected from damage due to static discharge by diode
clamps to V
DD
and V
SS
.

Note 1: "Absolute Maximum Ratings" are those values beyond which the
safety of the device cannot be guaranteed. They are not meant to imply
that the devices should be operated at these limits. The table of "Recom-
mended Operating Conditions" and "Electrical Characteristics" provides
conditions for actual device operation.
