PI74LPT16244CAEX

Buffers, Drivers, Receivers, Transceivers Overview

The PI74LPT16244CAEX is a 3.3V, 16-bit buffer/line driver designed for driving high capacitive memory loads. It features balanced-drive characteristics with 24mA sink and source output currents to minimize ground bounce and EMI. The device supports mixed-signal operation with inputs tolerant to 3V or 5V levels while outputs connect to 3V or 5V buses. It operates within a supply voltage range of 2.7V to 3.6V and an industrial temperature range of -40°C to +85°C. Propagation delay ranges from 1.5ns to 4.1ns depending on the speed grade.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Balanced drive capability providing equal 24mA sink and source currents for transmission line matching and reduced signal reflections.
• Supports 5V tolerant mixed-signal mode allowing direct interfacing between 3.3V and 5.0V devices.
• Configurable three-state controls enabling operation in Quad-Nibble, Dual-Byte, or single 16-bit word modes.

• Driving on-board buses
• Transmission line drivers
• High capacitive memory load interfaces

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'CAE' against official Diodes Incorporated documentation to confirm the package type, lead-free status, and tape/reel configuration. Ensure the required propagation delay specifications align with the 'C' speed grade limits defined in the datasheet electrical characteristics tables before finalizing procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring 16-bit buffering with high-speed performance and low power consumption. It is suitable for mixed-voltage environments where 3.3V logic must interface with 5V buses. Consider the TSSOP-48 package constraints and verify that the 24mA drive current meets the capacitive load requirements of the target memory or bus architecture.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the LPT series of advanced low-power CMOS logic devices manufactured by Diodes Incorporated (formerly Pericom). The LPT family is characterized by high-speed operation and compatibility with LCX and LVT standards. This specific model serves as a 16-bit buffer solution within the broader portfolio of bus drivers and transceivers offered by the manufacturer.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check for pin-compatible alternatives within the LPT series such as the PI74LPT16244AE or AA variants if different speed grades are acceptable. Verify that any substitute maintains the same 48-pin TSSOP footprint and 3.3V operating voltage range.
