DESCRIPTION

The DG2741, DG2742, DG2743 are low voltage, single supply, dual SPST analog switches. Designed for high performance switching of analog signals, the DG2741, DG2742, DG2743 provide low on-resistance (0.8 Ω at + 2.7 V), fast speed (tON, tOFF at 35 ns and 33 ns) and the ability to handle signals over the entire analog voltage range.
