LTC485IN8#PBF

Product Overview

The LTC485IN8#PBF from Analog Devices Inc. is a through-hole interface transceiver for RS422 and RS485 signaling. It integrates one driver and one receiver in an 8-PDIP package and operates from a 4.75 V to 5.25 V supply. The device supports half-duplex operation, with a 70 mV receiver hysteresis and an operating temperature range of -40°C to 85°C. Its 8-DIP (0.300 in, 7.62 mm) package uses through-hole mounting.

Design & Procurement Notes

For board layout, the 8-PDIP through-hole package requires holes and spacing consistent with a 0.300 in, 7.62 mm pitch. For procurement, specify the exact part number and 8-PDIP package. The 8-pin package also affects pin access and routing density on through-hole boards. The 4.75 V to 5.25 V supply range should be matched by the local power rail. Because the transceiver is half-duplex, system timing must separate transmit and receive states on the shared bus. The 70 mV receiver hysteresis should be considered when evaluating receiver input behavior. The -40°C to 85°C operating range should be considered in thermal layout.
