CD4001BC/CD4011BC Quad 2-Input NOR Buffered B Series Gate • Quad 2-Input NAND Buffered B Series Gate October 1987 Revised March 2002 CD4001BC/CD4011BC Quad 2-Input NOR Buffered B Series Gate • Quad 2-Input NAND Buffered B Series Gate General Description The CD4001BC and CD4011BC 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 are protected against static discharge with diodes to VDD and VSS. Features s Low power TTL: Fan out of 2 driving 74L compatibility: or 1 driving 74LS s 5V–1 [ ... ]
