DESCRIPTION
The PDI1284P11 parallel interface chip is designed to provide an
asynchronous, 8-bit, bi-directional, parallel interface for personal
computers. The part includes all 19 signal lines defined by the
IEEE1284 interface specification for Byte, Nibble, EPP, and ECP
modes. The part is designed for hosts or peripherals operating at
3.3V to interface 3.3V or 5.0V devices.
The 8 transceiver pairs (A/B 1-8) 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-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 400mV of input hysteresis at VCC = 3.3V.
