SN74ALVC244NSRE4

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ALVC244NSRE4 is an octal buffer and line driver manufactured by Texas Instruments, featuring 3-state outputs. It operates within a supply voltage range of 1.65 V to 3.6 V. The device provides a maximum propagation delay of 2.8 ns at 3.3 V and supports output drive currents up to ±24 mA at 3.3 V. It includes ESD protection exceeding JESD 22 specifications, with ratings of 2000 V for the human-body model, 200 V for the machine model, and 1000 V for the charged-device model. Latch-up performance exceeds 250 mA per JESD 17. The component is housed in a 20-pin NS (Small Outline Package) and functions as two independent 4-bit drivers with separate OE inputs.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the complete part number SN74ALVC244NSRE4 against official Texas Instruments documentation to confirm the specific NS package variant and tape-and-reel configuration. Ensure compatibility with the required 1.65 V to 3.6 V supply voltage range and check that the 20-pin SOP footprint matches the design layout. Confirm RoHS compliance status and lead finish details via the manufacturer's latest packaging addendum before finalizing procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring octal buffering with low-voltage operation between 1.65 V and 3.6 V. It is suitable for applications needing high-speed data transfer with propagation delays under 3 ns. Consider its 5-V tolerant input capability if interfacing with legacy 5-V logic levels. Verify that the 20-pin NS package dimensions fit the available PCB space and that the thermal characteristics meet the system's dissipation requirements.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the ALVC (Advanced Low-Voltage CMOS) logic family from Texas Instruments. It is designed for high-speed digital applications requiring low power consumption and wide voltage flexibility. The SN74ALVC244 series serves as a standard solution for buffering and driving data lines in modern electronic systems, offering improved speed over traditional LVC devices while maintaining compatibility with various logic families.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

SN74ALVC244NSR is the non-E4 version of the same component. SN74ALVC244PWR offers identical electrical characteristics in a TSSOP-20 package.
