The AG408 switches one of eight inputs to a common output as determined by the 3-bit binary address lines, and. The AG409 switches one of four differential inputs to a common differential output as determined by the 2-bit binary address lines and. An input on both devices is used to enable or disable the device. When disabled, all channels are switched OFF. The AG408/AG409 are designed on an enhanced LC 2 MOS process which provides low power dissipation yet gives high switching speed and low on resistance. Each channel conducts equally well in both directions when ON and has an input signal range that extends to the supplies. In the OFF condition, signal levels up to the supplies are blocked. All channels exhibit breakbefore-make switching action, preventing momentary shorting when switching channels. Inherent in the design is low charge injection for minimum transients when switching the digital inputs. The AG408/AG409 are improved replacements for the G408/G409 Analog Multiplexers. PROUCT HIGHLIGHTS 1. Extended Signal Range The AG408/AG409 are fabricated on an enhanced LC 2 MOS process giving an increased signal range that extends to the supply rails. 2. Low Power issipation 3 Low R ON 4. Single Supply Operation For applications where the analog signal is unipolar, the AG408/AG409 can be operated from a single rail power supply. The parts are fully specified with a single +12 V power supply and will remain functional with single supplies as low as +5 V.
