Maxim Integrated MAX3380ECUP+ RS-232 transceiver, full duplex 2/2 driver/receiver, 460 kbps data rate, 2.4 V to 5.5 V supply, 20-TSSOP package, 0°C to 70°C operating temperature.
| Parameter | Value |
|---|---|
| Type | Transceiver |
| Mounting type | Surface Mount |
| Voltage | 2.4V ~ 5.5V |
| Protocol | RS232 |
| Operating temperature | 0°C ~ 70°C |
| Duplex | Full |
| Package | Tube |
| Data rate | 460Kbps |
| Case | 20-TSSOP (0.173\", 4.40mm Width) |
| Receiver hysteresis | 300 mV |
| Number of drivers (Receivers) | 2/2 |
Receiver hysteresis is specified at 300 mV, giving noise margin on longer cable runs where ground potential shifts. The 0°C to 70°C temperature grade fits commercial equipment, office peripherals, and indoor instrumentation — not motor drives or outdoor telecom cabinets.
The MAX3380ECUP+ carries an Active product status and is ROHS3 compliant.
Yes. The supply range is 2.4 V to 5.5 V, so it operates directly on a 5 V rail without an external regulator. It also works on 3.3 V and 2.5 V rails.
Like most Maxim RS-232 transceivers, the MAX3380ECUP+ uses internal charge-pump capacitors. The datasheet specifies the required capacitor values and connections — typically four 0.1 µF or 1 µF capacitors for the charge pump. Verify the exact bill against the latest datasheet.
The MAX3380ECUP+ is an active, current-production part. Within the same family, the MAX3380E (without the CUP+ suffix) is the same die in a different ordering code — confirm pin-compatibility and temperature range before substituting. No direct second-source cross is listed in the official records.
