PDI1284P11DGG

3.3 V parallel interface transceiver/buffer

The PDI1284P11 parallel interface chip is designed to provide an asynchronous, 8-bit, bidirectional, parallel interface for personal computers. The PDI1284P11 includes all 19 signal lines defined by the IEEE 1284 interface specification for Byte, Nibble, EPP, and ECP modes. The PDI1284P11 is designed for hosts or peripherals operating at 3.3 V to interface 3.3 V or 5.0 V devices.

The eight transceiver pairs (A/B 1 to 8) allow data transmission from the A-bus to the B-bus, or from the B-bus to the A-bus, depending on the state of the direction pin DIR.

The B-bus and the Y9 to Y13 lines have either totem pole or resistor pull-up outputs, depending on the state of the high drive enable pin HD. The A-bus has only totem pole style outputs. All inputs are TTL compatible with at least 400 mV of input hysteresis at VCC = 3.3 V.

How does it work?

The interactive datasheets are based on the Nexperia MOSFET precision electrothermal models. With our interactive datasheets you can simply specify your own conditions interactively. Start by changing the values of the conditions. You can do this by using the sliders in the condition fields. By dragging the sliders you will see how the MOSFET will perform at the new conditions set.
