M74HC155
DESCRIPTION
P The M74HC155 is an high speed CMOS QUAD
2-INPUT NAND GATE fabricated with silicon gate te C2MOS technology. le It features dual 1 to 4 line demultiplexers with o individual strobe inputs (1G and 2G), individual s data inputs (1C and 2C) and mon binary b address inputs (A and B). O When both decoders are enabled by the strobes,
- the inverted output of 1C data and non-inverted ) output of 2C data will be brought to the select

M74HC155RM13TR M74HC155TTR output pins of each sections. A 1 to 8 line demultiplexer can also easily built up by providing a data signal to both 1C and 2C inputs; the output order from the msb is 1Y3, 1Y2, 1Y1, 1Y0, 2Y3, 2Y2, 2Y1, 2Y0. This device can be used as a 2 to 4 line decoder or a 3 to 8 line decoder when 1C is held high and 2C is held low. All inputs are equipped with protection circuits against static discharge and transient excess voltage.
