TPADN
Tristate buffer (non-inverting) with high enable (active-1).
Model
Operation
The TPADN is a tristate non-inverting buffer with active-high enable. When the enable input EN is high (1), the output Q equals the input D. When EN is low (0), the output goes to high-impedance state (Z).
| EN | D | Q |
|---|---|---|
| 1 | 0 | 0 |
| 1 | 1 | 1 |
| 0 | — | Z |
| X | — | X |
Multi-Input Enable
TPADN supports up to 14 enable inputs. When multiple enable inputs are used, all must be high (1) for the driver to be enabled. If any enable input is low (0), the output goes to high-impedance (Z).
Equivalent Type Statement
Type=TPADN i=EN[1:1-14],D o=QNote: The last input pin is always the data input D. All preceding inputs are enable pins.
