This device is included for compatibility with other XSPICE products. It is recommended that you use the digital buffer device (see Buffer) for new designs as this supports the additional common parameters such as static input loads and families.
The logic description for the open-collector buffer is described by the following table
| Input | Output state | Output strength |
|---|---|---|
| 0 | 0 | HI-IMPEDANCE |
| 1 | 1 | STRONG |
| UNKNOWN | UNKNOWN | UNDETERMINED |
