It is designed for two-way data communications over single-ended transmission lines. The transceiver features driver outputs that can be operated in either the open-collector or 3-state mode. If talk enable (TE) is high, these outputs have the characteristics of open-collector outputs when pullup enable (PE) is low and of 3-state outputs when PE is high. Taking TE low places the outputs in the high-impedance state. The driver outputs are designed to handle loads of up to 48 mA of sink current. Each receiver features pnp transistor inputs for high input impedance and 400 mV minimum of hysteresis for increased noise immunity. Output glitches during powe...
