特性
- High ESD protection on RS-485 outputs ±16.5kV HBM
- IEC61000-4-2 contact test method ±7kV
- Class 3 ESD level on all other pins >8kV HBM
- Specified for +125°C operation (VCC ≤ 3.6V only)
- Logic supply pin (VL) eases operation in mixed supply systems (ISL3298E only)
- Hot plug - Tx outputs remain three-state during power-up
- Low Tx leakage allows >256 devices on the bus
- High data rates up to 20Mbps
- Low quiescent supply current 150µA (max)
- Very low shutdown supply current 1µA (max)
- -7V to +12V common-mode output voltage range (VCC ≤ 3.6V only)
- Current limiting and thermal shutdown for driver overload protection (VCC ≤ 3.6V only)
- Tri-statable Tx outputs
- 5V tolerant logic inputs when VCC ≤5V
描述
A 26% smaller footprint is available with the ISL3298E TDFN package. This device also features a logic supply pin (VL) that sets the switching points of the DE and DI inputs to be compatible with a lower supply voltage in mixed voltage systems. For companion single RS-485 receivers in micro packages, please see the ISL3280E, ISL3281E, ISL3282E, ISL3283E, ISL3284E datasheet.
