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. Latch up protection exceeds 500 mA per JEDEC Std 19 Input Hysteresis Low Noise Operation IEEE 1284 Compliant Level 1 & 2 Overvoltage Protection on B/Y s...
