Description
2, 3, 1, 28
T1OUT to T4OUT
9, 4, 27, 23, 18 R1IN to R5IN
Transmitter (Driver) Outputs. Typically ±6 V.
Receiver Inputs. These inputs accept RS-232 signal levels. An internal 5 kΩ pull-down resistor to GND is
connected on each of these inputs.
8, 5, 26, 22, 19 R1OUT to R5OUT
7, 6, 20, 21
T1IN to T4IN
10
GND
Receiver Outputs. These are 3 V logic levels.
Transmitter (Driver) Inputs. These inputs accept 3 V or 5 V logic levels. An internal 400 kΩ pull-up resistor
to VCC is connected on each input.
Ground Pin. Must be connected to 0 V.
