Product details

The 4Mbps data rate suits moderate-speed industrial buses — think PLC-to-sensor links, building automation backplanes, or motor-drive status lines where the cable run stays under a few hundred metres. Supply voltage spans 4.75V to 5.25V, so it runs directly off a 5V rail without an external regulator. The 30 mV receiver hysteresis gives a noise margin that handles common-mode shifts on twisted-pair cabling in electrically noisy factory floors.

Temperature grade and package — design constraints

For industrial or automotive temperature exposure, the ADM4852ARZ extends the range to -40°C to 85°C. The 8-DIP through-hole package (0.300-inch row spacing) is a legacy footprint still common in breadboard prototyping, socketed modules, and wave-solder production lines. It mates with standard 8-pin DIP sockets or can be soldered directly into plated through-holes.

Lifecycle and supply posture

The ROHS3 compliance covers current EU and global solderability requirements.

Frequently asked questions

Is LTC1484CN8#PBF a half-duplex or full-duplex transceiver?

Half-duplex — the driver and receiver share the same bus pair, so the line must be turned around between transmit and receive. This is standard for multi-drop RS485 networks where only one node talks at a time.

Can LTC1484CN8#PBF work with 3.3V logic inputs?

The supply voltage is 4.75V–5.25V, and the logic input thresholds are referenced to that 5V rail. 3.3V logic may not reliably cross the VIH minimum — a level shifter or open-drain buffer is recommended between a 3.3V controller and this transceiver.

When sourcing LTC1484CN8#PBF, what is the closest functional second-source — ADM485JNZ?

The ADM485JNZ is a near pin-compatible half-duplex RS485 transceiver in the same 8-DIP package, with a slightly higher 5Mbps data rate and a larger 70 mV receiver hysteresis. It operates over the same 0°C–70°C commercial range. Confirm the receiver hysteresis difference — 70 mV vs 30 mV — may affect noise margin on long cable runs.
