PDI1284P11DGG,118

Specialized Overview

The PDI1284P11 is a 3.3 V parallel interface transceiver and buffer designed for asynchronous, 8-bit bidirectional communication compliant with IEEE 1284 Byte, Nibble, EPP, and ECP modes. It supports host or peripheral operation at 3.3 V to interface with 3.3 V or 5.0 V devices. The device includes eight transceiver pairs (A/B 1-8), five cable-side control inputs (C14-C17), and four peripheral control outputs (A14-A17). Operating conditions specify a supply voltage of 3.0 V to 3.6 V for the main logic and 3.0 V to 5.5 V for the cable side. Propagation delays range from 0 ns to 23 ns depending on direction and load.

Specialized Feature Summary

• Supports IEEE 1284 Level 1 and Level 2 compliance for standard parallel interfaces
• Provides configurable B/Y side output drive options including totem pole and resistive pull-up
• Features 5 V tolerant I/O pins allowing safe interfacing between different voltage domains
• Includes integrated ESD protection exceeding 2000 V HBM and 500 mA latch-up current capability

Specialized Applications

• Asynchronous parallel interface connections for personal computers
• Interfacing 3.3 V hosts with 5.0 V peripherals in mixed-voltage environments
• Implementation of Enhanced Parallel Port (EPP) and Extended Capability Port (ECP) protocols

Specialized Procurement Notes

Verify the specific ordering suffix against the manufacturer's current product status documentation before design finalization. Confirm that the TSSOP48 package dimensions align with the target PCB footprint requirements. Ensure that the ambient operating temperature range of 0 °C to 70 °C meets the environmental constraints of the intended application environment.

Specialized Selection Notes

Select this component when an 8-bit bidirectional parallel data path is required between systems operating at different voltage levels. The device is suitable for designs needing flexible output drive configurations via the HD pin. Verify that the maximum propagation delay specifications meet the timing requirements of the specific parallel protocol implementation being utilized.
