Texas Instruments’ MUX506, MUX507, MUX508, and MUX509 (MUX50x) are complementary metal-oxide semiconductor (CMOS), analog multiplexers (muxes). The MUX506 offers 16:1 single-ended channels; the MUX507 offers differential 8:1 or dual 8:1 single-ended channels; the MUX508 offers 8:1 single-ended channels; and the MUX509 offers differential 4:1 (8:2) channels. The MUX508 and MUX509 work equally well with either dual supplies (±5 V to ±18 V) or a single supply (10 V to 36 V). They also perform well with symmetric supplies (such as VDD = 12 V, VSS = -12 V), and asymmetric supplies (such as VDD = 12 V, VSS = -5 V). All digital inputs have TTL-logic compatible thresholds, ensuring both TTL and CMOS logic compatibility when operating in the valid supply voltage range.
The MUX506, MUX507, MUX508, and MUX509 have very low on and off leakage currents, allowing these multiplexers to switch signals from high input impedance sources with minimal error. A low supply current of 45 µA allows for use in portable applications.
