RS232 transceiver, 2/2, 1Mbps, 3V–5.5V
The SN65C3223EPWR: It handles serial data at rates up to 1 Mbps, making it suitable for point-to-point or multi-drop RS232 links in industrial and telecom equipment.
Supply voltage and temperature grade
Receiver hysteresis is specified at 500 mV, which rejects noise on longer cable runs — a practical margin when the transceiver sits at the end of a 15-metre RS232 line in a noisy electrical cabinet.
Package and board integration
Housed in a 20-TSSOP (4.40 mm width) with surface-mount termination. The fine-pitch leads require a controlled solder profile; a 0.50 mm stencil aperture for the pads keeps paste volume consistent. The package is ROHS3 compliant per.
