PDI1284P11DGG,512

Specialized Overview

The PDI1284P11DGG,512 is a 3.3 V parallel interface transceiver and buffer designed for asynchronous, 8-bit bidirectional data transmission between personal computer hosts and peripherals. It implements all 19 signal lines defined by the IEEE 1284 specification for Byte, Nibble, EPP, and ECP modes. The device supports host or peripheral operation at 3.3 V while interfacing with 3.3 V or 5.0 V devices. It features eight transceiver pairs (A/B 1 to 8) controlled by a direction pin, alongside six additional buffer/driver lines and five control lines. The B-bus and Y9 to Y13 outputs can be configured as totem pole or resistor pull-up depending on the high drive enable pin. All inputs are TTL compatible with input hysteresis.

Specialized Feature Summary

• IEEE 1284 compliant level 1 and 2 support for Byte, Nibble, EPP, and ECP modes
• 5 V tolerant inputs and outputs with overvoltage protection on the B/Y side
• Configurable B-side output types including active totem pole and resistive pull-up options
• ESD protection exceeding 2000 V per HBM and 200 V per MM standards

Specialized Applications

• Asynchronous parallel interfaces for personal computers
• Host-to-peripheral communication in printer systems
• Data transmission between 3.3 V and 5.0 V logic domains

Specialized Procurement Notes

Verify the specific ordering suffix against the manufacturer's current catalog to confirm package type and temperature range. Confirm RoHS compliance status and check for any product change notices related to assembly sites or marking updates before finalizing procurement plans.

Specialized Selection Notes

Select this component when designing an IEEE 1284 compliant parallel interface requiring 3.3 V logic levels. Ensure the application voltage does not exceed the recommended operating conditions of 3.0 V to 3.6 V for VCC and 3.0 V to 5.5 V for VCC(B). Verify that the required propagation delay and slew rate specifications meet the system timing requirements.

Specialized Part Context

This part belongs to the PDI1284 series of parallel interface transceivers manufactured by Nexperia. It serves as a bridge between host controllers and peripheral devices, specifically addressing the electrical and protocol requirements of legacy parallel ports. The TSSOP48 package provides a compact solution for space-constrained designs.

Specialized Replacement Considerations

Check for direct replacements within the PDI1284 family such as the PDI1284P11DL if SSOP48 packaging is preferred. Verify functional compatibility regarding pinout and electrical characteristics before substituting.
