Communication interface chip UART485/232

The NLAS5157 is a single-pole, double-throw (SPDT) switch for audio systems in portable applications. The NLAS5157 has very low on-resistance over temperature, 0.4 Ω typical at VCC = 3.0 V, and 0.15 Ω stable on-resistance for +3.0 V supply.

5V, Crosspoint/Switch, 24-Channel FET Bus Switch with Schottky Diode Clamp 56-TSSOP -40 to 85
