The Maxim MAX3082CPA+ is a high-speed transceiver for RS-485 / RS-422 communication and contains one driver and one receiver. The device features fail-safe circuitry which guarantees a logic-high receiver output when the receiver inputs are open or shorted. This means that the receiver output will be a logic high if all transmitters on a terminated bus are disabled (high impedance).

• Maxim type MAX3082CPA+

These Texas Instruments MAX232N devices are designed to convert between TTL voltage levels (0 to 5V) and TIA/EIA-232-F levels (±30V). They operate from a single 5VDC power supply with charge-pump capacitors for situations where multiple supply voltages are not available such as battery powered or compact systems.

• Meets or exceeds TIA/EIA-232-F and ITU recommendation V.28
• Operates up to 120kbit/s
• ±30V input levels
• Low supply current
• DIL-16

We also supply a range of EIA-232 devices from Maxim.
