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