LTC2862CS8-2#PBF

Product Overview

The LTC2862CS8-2#PBF from Analog Devices Inc. is a 1/1 transceiver for RS422 and RS485 serial interfaces. It operates in a half-duplex mode and provides one driver and one receiver in an 8-SOIC surface-mount package with a 0.154 in, 3.90 mm width. The device accepts a 3V to 5.5V supply and is specified for a 250kbps data rate. Its 150mV receiver hysteresis is a receiver characteristic for differential serial links, while the 0°C to 70°C operating range defines the ambient conditions for normal use.

Design & Procurement Notes

Design reviews should confirm that the system supply remains within 3V to 5.5V and that the local ambient environment stays between 0°C and 70°C. The 8-SOIC surface-mount package requires a compatible footprint and solder process. Because the device is a 1/1 half-duplex transceiver, the link topology and protocol timing should be matched to the host or controller design. The 250kbps data rate should be compared with the required link speed, and the 150mV receiver hysteresis should be considered when evaluating input signal margins. Procurement comparisons should focus on package size, supply range, protocol compatibility, and thermal limits.
