PI74LPT16244AEX

Buffers, Drivers, Receivers, Transceivers Overview

The PI74LPT16244AEX is a 16-bit buffer and line driver manufactured by Diodes Incorporated, designed for driving high capacitive memory loads. It operates within a supply voltage range of 2.7V to 3.6V and supports industrial temperatures from -40°C to +85°C. The device features balanced drive capabilities with 24mA sink and source currents, ensuring low ground bounce and reduced EMI/RFI effects. Propagation delay ranges from 1.5ns to 4.8ns depending on the specific grade, with output enable/disable times up to 6.2ns. It utilizes a 48-pin TSSOP package.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Supports mixed-signal mode operation allowing inputs of 3V or 5V while outputs connect to 3V or 5V buses.
• Provides balanced drive characteristics to minimize switching noise, transmission line reflections, and electromagnetic interference.
• Features three-state controls enabling operation in Quad-Nibble, Dual-Byte, or single 16-bit word modes.

Buffers, Drivers, Receivers, Transceivers Applications

• Driving on-board buses
• Transmission line matching
• Mixed 3.3V/5.0V system translation

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the component grade suffix (C or A) against project requirements, as propagation delays vary between grades. Confirm the 'E' suffix indicates Pb-free and Green packaging status. Ensure the 'X' suffix is present if tape-and-reel delivery is required rather than tube packaging. Cross-reference the manufacturer part number with the distributor listing to ensure correct pinout compatibility.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when driving high capacitive loads requiring low ground bounce and signal integrity. It is suitable for applications needing translation between 3.3V and 5.0V logic levels. Consider the specific propagation delay grade required for timing constraints. Verify that the 48-pin TSSOP footprint matches the PCB layout design.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the LPT series of advanced low-power CMOS logic products. It is compatible with LCX and LVT families, offering pin-compatible double-density layouts. The product line focuses on high-speed performance with minimal power consumption, addressing the needs of modern digital systems requiring efficient bus driving and signal buffering.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check for direct replacements within the same LPT family or compatible LCX/LVT devices. Ensure any substitute maintains the 48-pin TSSOP form factor and balanced drive current specifications. Verify voltage tolerance and operating temperature ranges match the original application requirements.
