RS232 interface with 500 mV receiver hysteresis
The MAX243CSE+: Data rate tops out at 200 kbps, and the receiver hysteresis is specified at 500 mV — this filters noise on longer cable runs without external schmitt triggers.
Supply and temperature envelope
The commercial temperature grade (0°C to 70°C) suits indoor terminal equipment, point-of-sale gear, and desktop peripherals. Housed in a 16-SOIC (0.154-inch body width, 3.90 mm) with a surface-mount footprint. The tube packaging is standard for prototype and low-volume assembly.
The part is ROHS3 compliant, covering the current EU exemption scope.
