Produktöversikt
The SP330EEY-L is an advanced Multi-protocol Transceiver supporting RS-232, RS-485 and RS-422 serial standards and featuring a variable low voltage logic interface, down to 1.65V. Full operation requires only four external charge pump capacitors. The RS-485/RS-232 mode pin selects RS-485 mode when high and RS-232 mode when low. In RS-485 mode the HALF/FULL pin configures the transceiver as either half or full duplex. The high speed driver operates up to 20Mbps in RS- 485/422 modes and up to 1Mbps in RS-232 mode. All drivers can be slew limited to 250kbps in any mode to minimize electromagnetic interference (EMI) by setting the dedicated SLEW pin low. Each receiver output has full fail-safe protection to avoid system lockup, oscillation or indeterminate states by defaulting to logic-high output level when the inputs are open, shorted or terminated but undriven. No external biasing resistors are required. The RS-232 receiver inputs include a 5kW pull-down to ground when in RS-232 mode.
- Robust ESD protection
- Full or half duplex configuration
- 1/8 Unit-load (up to 256 nodes on the bus)
- RS-485/422 Enhanced receiver failsafe for open, shorted or terminated but idle inputs
- 10nA Typical shutdown supply current
