It supports data rates up to 2.5 Mbps over balanced transmission lines, making it suitable for industrial multi-drop networks or point-to-point links where differential signaling rejects common-mode noise. Housed in a 14-lead PDIP (0.300\" body width) with through-hole mounting, this part is a direct fit for breadboard prototyping or legacy PCB designs that avoid surface-mount assembly. ## Receiver hysteresis and temperature grade The receiver includes 70 mV of hysteresis, which prevents output chatter on slowly changing or noisy differential inputs — a practical benefit when the cable run picks up coupled interference from adjacent motor drives or switching supplies. Rated for the commercial temperature range of 0°C to 70°C, this variant is intended for indoor equipment, lab instrumentation, or controlled-environment industrial panels. For extended-temperature applications, the industrial-grade MAX491E variants cover -40°C to +85°C.","metaTitle":"MAX491ECPD+ RS-422/485 Transceiver, 2.5 Mbps, 14-PDIP","metaDescription":"Analog Devices MAX491ECPD+ RS-422/485 full-duplex transceiver, 2.5 Mbps data rate, 1/1 driver/receiver, 14-PDIP.
