Features
ISL32603E are В±15kV IEC61000 ESD protected, micro power,
wide supply range transceivers for differential communication.
The ISL32600E and ISL32601E operate with VCC ≥ 2.7V and
have maximum supply currents as low as 100ВµA with both the
transmitter (Tx) and receiver (Rx) enabled. The ISL32602E and
ISL32603E operate with supply voltages as low as 1.8V. These
transceivers have very low bus currents, so they present less
than a “1/8 unit load” to the bus. This allows more than 256
transmitters on the network, without violating the RS-485
specification’s 32 unit load maximum. Single 1.8V, 3V, or 3.3V Supply Rx inputs feature symmetrical switching thresholds, and up to
65mV of hysteresis, to improve noise immunity and to reduce
duty cycle distortion in the presence of slow moving input
signals (see Figure 9). The Rx input common mode range is the
full -7V to +12V RS-485 range for supply voltages ≥ 3V. Up to 65mV Hysteresis for Improved Noise Immunity Hot Plug circuitry ensures that the Tx and Rx outputs remain in
a high impedance state while the power supply stabilizes. -7V to +12V Common Mode Input/Output Voltage Range
(VCC ≥ 3V) This transceiver family utilizes slew rate limited drivers, which
reduce EMI, and minimize reflections from improperly terminated
transmission lines, or unterminated stubs in multidrop and …
