General Description
Employing complementary MOS (CMOS) transistors to
achieve wide power supply operating range, low power con-
sumption, and high noise margin, the CD4070BM/BC and
CD4077BM/BC provide basic functions used in the imple-
mentation of digital integrated circuit systems. The N- and
P-channel enhancement mode transistors provide a sym-
metrical 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 in-
puts are protected from damage due to static discharge by
diode clamps to V
