Layout symbol
Dual 2-to-4 line decoder/demultiplexer: Both halves share the address inputs A and B, which pick one of four active-low outputs in each half. Half 1 is enabled by 1G low and 1C high, half 2 by 2G and 2C both low. Tie 1C to 2C and 1G to 2G to make a 3-to-8 decoder, with C as the third address bit.
