Overview

Part: MAX232 from Texas Instruments

Type: Dual EIA-232 Drivers and Receivers

Description: The MAX232 is a dual driver/receiver that includes a capacitive voltage generator to supply TIA/EIA-232-F voltage levels from a single 5V supply, operating up to 120 kbit/s with two drivers and two receivers, and accepting ±30V input levels.

Operating Conditions:

  • Supply voltage: 4.5–5.5 V
  • Operating temperature: 0 to 70 °C (for MAX232)
  • Max data rate: 120 kbit/s

Absolute Maximum Ratings:

  • Max supply voltage: 6 V
  • Max junction temperature: 150 °C
  • Max storage temperature: -65 to 150 °C

Key Specs:

  • Supply current (ICC): 8 mA typical, 10 mA max (VCC = 5.5V, all outputs open, TA = 25°C)
  • Driver high-level output voltage (VOH): 5 V min, 7 V typical (RL = 3kΩ to GND)
  • Driver low-level output voltage (VOL): -7 V typical, -5 V max (RL = 3kΩ to GND)
  • Receiver input voltage range (R1IN, R2IN): ±30 V
  • Receiver input hysteresis voltage (Vhys): 0.2 V min, 0.5 V typical, 1 V max (VCC = 5V)
  • Receiver input resistance (rI): 3 kΩ min, 5 kΩ typical, 7 kΩ max (VCC = 5V, TA = 25°C)
  • Driver slew rate (SR): 30 V/μs max
  • ESD protection (HBM): 2000 V

Features:

  • Meets or exceeds TIA/EIA-232-F and ITU recommendation V.28
  • Operates from a single 5V power supply with 1μF charge-pump capacitors
  • Operates up to 120kbit/s
  • Two drivers and two receivers
  • ±30V Input levels
  • Low supply current: 8mA typical
  • ESD protection exceeds JESD 22
  • -2000V Human-body model (A114-A)
  • Upgrade with improved ESD (15kV HBM) and 0.1μF charge-pump capacitors is available with the MAX202 device

Applications:

  • TIA/EIA-232-F
  • Battery-powered systems
  • Terminals
  • Modems
  • Computers
