The four Ethernet 10/100BaseT auto-sensing UTP Ports use RJ-45 connectors with Full and Half-Duplex
This high-performance IC is a half-duplex
transceiver whose receive (Rx) and transmit (Tx) functions are multiplexed, reducing size and pin count to only 8-leads in an SOIC package.
Applications for these half-duplex
transceivers include, but are not limited to, PROFIBUS DP or FMS for factory automation, SCSI "Fast 40" and "Fast 20" drivers and receivers, Field Bus networks, security networks, process control, plant environmental control and remote sensing and metering.
All three ICs are half-duplex
fractional-load transceivers that operate from a nominal 5-V supply over a wide +/-10% tolerance voltage range of +4.
This "walkie-talkie" style push-to-talk feature of the Nokia 5140 phone is a half-duplex
voice over IP (VoIP) solution using the existing GPRS and EDGE data networks that are part of current GSM systems.
The ISL8487, ISL81483 and ISL81487 are half-duplex
transceivers whose receive (Rx) and transmit (Tx) functions are multiplexed, reducing package size and pin count to only 8-leads.
