MAX3238E - RS-232 Transceivers

General Description

The MAX3238E/MAX3248E transceivers use Maxim’s revolutionary AutoShutdown Plus™ feature to achieve 10nA supply current.

These devices shut down the onboard power supply and drivers when they do not sense a valid signal transition on either the receiver or transmitter inputs.

Key Features

  • o Enhanced ESD Protection on RS-232 I/O Pins and All Logic Pins ±15kV.
  • Human Body Model ±8kV.
  • IEC 1000-4-2 Contact Discharge ±15kV.
  • IEC 1000-4-2 Air-Gap Discharge o Guaranteed Data Rate: 250kbps o 10nA Low-Power Shutdown with Receivers Active o Schmitt Triggers on All Inputs o Flow-Through Pinout o Meets EIA/TIA-232 Specifications Down to 3.0V o Guaranteed 6V/µs Slew Rate o Low-Level Logic Thresholds (MAX3248E) o RS-232-Compatible Outputs to 2.7V MAX3238E/MAX3248E† Orderin.

19-1632; Rev 1; 6/01 +3.0V to +5.5V, 10nA, 250kbps RS-232 Transceivers with ±15kV ESD-Protected I/O and Logic Pins General Description The MAX3238E/MAX3248E transceivers use Maxim’s revolutionary AutoShutdown Plus™ feature to achieve 10nA supply current. These devices shut down the onboard power supply and drivers when they do not sense a valid signal transition on either the receiver or transmitter inputs. This occurs if the RS-232 cable is disconnected or if the transmitters of the connected peripheral are turned off. The devices turn on again when a valid transition is applied to any RS-232 receiver or transmitter input. AutoShutdown Plus automatically achieves this power savings through its on-board circuitry, as no changes are required to the existing BIOS or operating system.
