and a true fail-safe receiver, guaranteeing a logic-high
receiver output when inputs are shorted or open. Hot-
swap capability eliminates undesired transitions on the
bus during power-up or hot insertion.
The transceiver draws 1.9mA (typ) supply current when
unloaded or when fully loaded with the drivers disabled
and draws less than 10µA (max) of supply current in low-
power shutdown mode.
The MAX14783E is available in 8-pin µMAX, 8-pin SO,
and small, 8-pin (3mm x 3mm) TDFN-EP packages.
The device in the TDFN-EP package operates over the
-40°C to +125°C temperature range. The MAX14783E in
the µMAX and SO packages operates over the -40°C to
+85°C and -40°C to +125°C temperature ranges.
