It integrates three line drivers that convert TTL\/CMOS logic levels (0-3.3V or 0-5V) to RS-232 levels (+\/-5V to +\/-7V) using an internal charge-pump voltage converter. The dual charge pump uses four external 0.1uF capacitors: two for the voltage doubler (VCC to +2xVCC) and two for the voltage inverter (+2xVCC to -2xVCC). The driver output swing is typically +\/-6.5V at 5V supply and +\/-5.0V at 3.3V supply, exceeding the RS-232 minimum of +\/-5V. The five receivers convert RS-232 input levels (as low as +\/-3V) to TTL\/CMOS logic levels. Three of the five receivers are always active (RIN1-RIN3), while the remaining two can be enabled\/disabled via the EN pin. The SHDN (shutdown) pin reduces power consumption to 1uA by disabling the charge pump and all outputs. The -L suffix indicates the low-voltage (3.0-5.5V) version; the -\/TR suffix indicates tape-and-reel packaging. The 3-driver\/5-receiver configuration is optimized for a standard serial port with full modem control (TX, RX, RTS, CTS, DSR, DTR, DCD, RI).","pin_description":"
