MM74C154N

Revised January 2004 MM74C154 4-Line to 16-Line Decoder/Demultiplexer General Description Features The MM74C154 one of sixteen decoder is a monolithic complementary MOS (CMOS) integrated circuit constructed with N- and P-channel enhancement transistors. The device is provided with two strobe inputs, both of which must be in the logical “0” state for normal operation. If either strobe input is in the logical “1” state, all 16 outputs will go to the logical “1” state. ■ Supply voltage range: To use the product as a demultiplexer, one of the strobe inputs serves as a data input terminal, while the other strobe input must be maintained in the logical “0” state. The information will then be transmitted to the selected output as determined by the 4-line input address. • Automotive 3V to 15V ■ Tenth power TTL compatible: Drive 2 LPTTL loads ■ High noise margin: 1V guaranteed ■ High noise immunity: 0.45 VCC (typ.)
