SN74LVC2244APWRE4

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVC2244APWRE4 is an octal buffer and line driver manufactured by Texas Instruments. It operates within a supply voltage range of 1.65 V to 3.6 V and features eight non-inverting channels organized into two independent four-bit sections. Each section includes a dedicated output enable (OE) input for controlling data flow. The device utilizes a 20-pin TSSOP package with a maximum width of 4.40 mm. It supports mixed-mode signal operations across all ports, allowing inputs to accept voltages up to 5.5 V regardless of the VCC level. The component is designed for asynchronous communication between data buses.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'E4' indicates RoHS compliance and lead-free status as per manufacturer documentation. Confirm the package type matches the required PCB footprint. Ensure the operating temperature range meets system requirements. Check for any specific ordering prefixes or alternative suffixes that may affect availability or specifications.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal buffer with independent control is required for low-voltage applications. Consider the 1.65 V minimum supply voltage for compatibility with modern low-power systems. Evaluate the 5.5 V input tolerance if interfacing with higher voltage logic sources without additional level shifting circuitry.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LVC2244A series of octal buffers and line drivers. It is functionally similar to the SN74LVC244 but may differ in specific electrical characteristics or packaging options. The 'PWR' designation indicates a 20-pin TSSOP package, while 'E4' typically denotes environmental compliance attributes defined by the manufacturer.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The SN74LVC2244APWR is a compatible variant without the E4 suffix, potentially differing only in packaging or compliance details. Verify pinout compatibility before substitution. Other LVC series buffers may serve as alternatives if electrical parameters align with design constraints.
