SN74LVC2244ADWRE4

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVC2244ADWRE4 is an octal buffer and line driver featuring three-state outputs, manufactured by Texas Instruments. It operates within a supply voltage range of 1.65V to 3.6V and accepts input voltages up to 5.5V, facilitating level shifting between different logic families. The device provides low output impedance for driving capacitive loads and includes typical output ground bounce (VOLP) specifications of less than 0.8V at VCC = 3.3V and TA = 25°C. It is housed in a 20-pin SOIC package.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'E4' indicates lead-free compliance and RoHS status as per manufacturer documentation. Confirm the 'R' suffix corresponds to tape-and-reel packaging when ordering. Ensure the SOIC-20 package dimensions match your PCB footprint requirements before finalizing procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal buffer with level-shifting capabilities is required for mixed-voltage environments. It is suitable for applications needing high-speed performance with low power consumption. Consider the 3-state output feature if bidirectional bus control or multiple drivers sharing a common line is necessary for the system design.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LVC2244A family of octal buffers and line drivers. It is part of Texas Instruments' LVC (Low-Voltage CMOS) logic series, designed for low-power applications operating at supply voltages down to 1.65V. The family emphasizes high speed and compatibility with various logic standards.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check for SN74LVC2244ADWR as a standard reel version without the E4 suffix. Verify pinout compatibility with other octal buffers like the SN74LVC244A, noting that input/output configurations may differ.
