* **Technology:** Surface Mounted Technology (SMT).
* **Integration:** Four units can be mounted on a carrier board for up to 64 differential or 128 single-ended channels per VMEbus or ISA bus slot.

**Compatibility:**
* **IP Compliance:** Meets IP specifications per ANSI/VITA 4-1995.
* **Data Transfer Cycle Types:** Input/output (IOSel*), ID read (IDSel*), Interrupt select (INTSel*).
* **Access Times (8MHz clock):**
* ID PROM read: 1 wait state (375nS cycle).
* I/O space read/write: 1 wait state.

* 3 wait states if ongoing internal mailbox write.
* **Carrier Cards:** Acromag offers a selection of Industry Pack Carrier Cards.

**Isolation:**
* **Non-Isolated:** The IP330 is non-isolated, meaning there is electrical continuity between logic and field I/O grounds. Field I/O connections are not isolated from the carrier board and backplane. Careful installation is recommended to prevent noise pickup and ground loops.
