说明

The SN75LBC241 is a low-power LinBiCMOS^TM line-interface device containing four independent drivers and five receivers. It is designed as a plug-in replacement for the Maxim MAX241. The SN75LBC241 provides a capacitive-charge-pump voltage generator to produce RS-232 voltage levels from a 5-V supply. The charge-pump oscillator frequency is 20 kHz. Each receiver converts RS-232 inputs to 5-V TTL/CMOS levels. The receivers have a typical threshold of 1.2 V and a typical hysteresis of 0.5 V and can accept ±30-V inputs. Each driver converts TTL/CMOS input levels into RS-232 levels.

The SN75LBC241 includes a receiver, a 3-state control line, and a low-power shutdown control line. When the EN\ line is high, receiver outputs are placed in the high-impedance state.
