Data sheet:
Material Declaration:
The ST4E1216 and ST4E1240 are low-power differential line transceivers for data transmission standard RS485 applications in half-duplex mode, compatible with either 3.3 V or 5 V rail power supplies, fully operating from 3 V to 5.5 V.
The ST4E1216 and the ST4E1240 operate respectively up to 16 Mbps and 40 Mbps. They are ideal for multipoint applications over extended cable runs. They are robust to ESD transients. In particular, the bus pins support ±12 kV IEC 61000-4-2 contact discharge. They also feature robust hot-swap capability during switching on and off, or during hot insertion.
The ST4E1216 is available in SO8 and up to 125 °C. The ST4E1240 is available in SO8 and DFN8 with two temperature range as stated in the device summary table.
- Meets or exceeds TIA/EIA-485A standard requirements
- 3 V to 5.5 V supply voltage
- Differential output voltage (VOD) exceeds 2.1 V at 5 V supply for PROFIBUS compatibility
- High speed: up to 40 Mbps data rate
- More than 64 transceivers on the bus (up to 100 nodes)
- Integrated protections
- Fail-safe receiver (bus open, idle, and shorted)
- Thermal shutdown protection
- Hot-swap capability (with parasitic capacitance up to 100 pF)
- Bus I/O ESD protection ±12 kV IEC61000-4-2 contact discharge ±30 kV HBM ±4 kV IEC61000-4-4 class-A fast transient burst (EFT)
- Low quiescent current in shutdown mode
- Available in industry standard SO-8 and DFN8 for the ST4E1240
