四2输入多路复用器 Quad 2-Input Multiplexers
General Description
The MM74C157 multiplexers are monolithic complementary MOS CMOS integrated circuits constructed with N and P-channel enhancement transistors. They consist of four 2-input multiplexers with common select and enable inputs. When the enable input is at logical “0” the four outputs assume the values as selected from the inputs. When the enable input is at logical “1”, the outputs assume logical “0”. Select decoding is done internally resulting in a single select input only.
Features
■ Supply voltage range: 3V to 15V
■ High noise immunity: 0.45 VCC typ.
■ Low power: 50 nW typ.
■ Tenth power TTL compatible: Drive 2 LPTTL loads
