Product details

Through-hole package — field-service friendly

The 8-DIP package (0.300" body, 7.62 mm pitch) is a socketable, hand-solderable part. If you are maintaining legacy PLC or SCADA panels, this is the kind of transceiver you can swap on site with a basic iron and a solder sucker — no hot-air station, no reflow profile. The 50 mV of receiver hysteresis helps reject noise on an idle bus, which is a real help when you are troubleshooting a flaky line without a scope handy.

Maxim lists the MAX3488EPA+ as Active and ROHS3 compliant.

Frequently asked questions

Is MAX3488EPA+ the correct replacement for MAX3488ESA+ in through-hole designs?

Yes — the MAX3488EPA+ is the through-hole (PDIP) version of the same transceiver core. The MAX3488ESA+ is the surface-mount (SOIC) variant. Electrically identical; the EPA+ swaps into a DIP socket footprint.

Can MAX3488EPA+ operate with a 3.0V supply and at 250 kbps over long RS-485 cable runs?

Yes. The supply range is 3V to 3.6V, so 3.0V is within spec. The 250 kbps data rate is deliberately chosen for robust signal integrity over long cable runs — the slower edge rate reduces reflections and EMI on extended RS-485 buses.

Is MAX3488EPA+ compatible with 3.3V systems?

Yes — the 3V to 3.6V supply range covers 3.3V nominal. It is a direct fit for 3.3V logic and bus rails.
