Product details

It operates from a 4.75V to 5.25V supply rail and signals at up to 2.5 Mbps — fast enough for industrial fieldbus links, sensor networks, and PLC-to-drive communication over twisted-pair cable. The 45 mV receiver hysteresis cleans up noisy bus signals, reducing false edge triggers on long cable runs.

Through-hole package and hand-solder fit

The 8-DIP (0.300", 7.62 mm) through-hole package is breadboard-friendly and easy to hand-solder — no hot-air station needed. The 0.100-inch pin pitch matches standard prototyping grids, and the body width fits 300-mil DIP sockets. For a maker or low-volume build, this is the package that keeps assembly simple.

Active production and compliance status

It is ROHS3 compliant, so it ships lead-free and meets the EU RoHS directive for unrestricted global distribution.

Frequently asked questions

What is the closest functional second-source to LTC1481IN8#PBF?

The ADM485JNZ is a through-hole half-duplex RS-485/RS-422 transceiver with the same 1/1 driver/receiver count and 4.75V–5.25V supply, but its data rate is 5 Mbps (double) and its receiver hysteresis is 70 mV (higher). The ADM4852ARZ is a surface-mount alternative with 20 mV hysteresis, also limited to 0°C–70°C.

Is LTC1481IN8#PBF lead-free?

Yes, it is ROHS3 compliant, meaning it meets the lead-free and restricted-substance limits of the EU RoHS directive.
