The AD7306 is a +5 V powered RS-232/RS-422 transceiver that can operate from a single +5 V power supply. It features short circuit protection, excellent noise immunity and low power, and is suitable for applications such as DTE-DCE interfaces, packet switching, local area networks, data concentration, data multiplexers and integrated services digital network (ISDN).
The AD7306 is a 5 V monolithic line driver/receiver that provides an interface between TTL levels and dual‑standard RS‑232/RS‑422 signal levels. It contains two RS‑232 drivers, one RS‑422 driver, one RS‑232 receiver and a configurable receiver path, all powered from a single +5 V supply with an internal charge pump generating ±10 V.
The document includes functional block diagrams, electrical specifications, timing data, ordering information, pin descriptions, typical performance curves, and a comparison of single‑ended (RS‑232) and differential (RS‑422) interfaces, helping designers select the appropriate package and configure the device for their application.

It operates from a single +5 V supply, with an internal charge pump that generates ±10 V for the RS‑232 drivers.
The device contains two RS‑232 drivers, one RS‑422 driver, one RS‑232 receiver, and a configurable receiver path.
The RS‑422 driver can transmit data up to 5 MHz.
It is offered in a 24‑lead SOIC (R‑24) and a 24‑pin plastic DIP (N‑24).
