4081 CMOS四2输入端与门

The CD4071BC and CD4081BC quad gates are monolithic

complementary MOS (CMOS) integrated circuits constructed

with N- and P-channel enhancement mode transistors.

They have equal source and sink current

capabilities and conform to standard B series output drive.

The devices also have buffered outputs which improve

transfer characteristics by providing very high gain.

All inputs protected against static discharge with diodes to

VDD and VSS.
