Communication interface chip UART485/232

The NLAS4053 is an improved version of the MC14053 and MC74HC4053, using a sub-micron silicon gate CMOS process with lower RDS(on) and improved linearity at low currents. The device can operate from a single supply or dual supplies up to +/- 3V and can pass 6 VPP signals without coupling capacitors. When operating in single-supply mode, only VEE, pin 7, needs to be connected to ground. For dual-supply operation, VEE is connected to a negative voltage in order not to exceed the maximum rating. Pin-to-pin compatible with all industry standard "4053" versions.
