† _{12 mA for 1284 control, 3 mA for all other outputs}
‡ _{Applies to external input and bidirectional buffers with hysteresis. All input buffers have hysteresis.}
§ _{A 3-state or open-drain output must be in the high-impedance state.}
NOTE 4: All 1284 output and data terminals are low-noise TTL 12 mA drivers. The type of the driver, push/pull or open drain, is switched
dynamically based on the 1284 mode.
