Figure 29. Adding extra differential and single-ended transceivers using the SP332
Note: The SP332 will require clamping
diodes on the driver outputs to limit the
voltage to +/-6V and comply with the RS-423
driver output specification of Voc = +/-4.0V to
+/-6.0V and VOUT ≥ +/-3.6V with a 450Ω load.
