SN74ACT244PWRE4

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ACT244PWRE4 is an octal buffer and line driver manufactured by Texas Instruments, belonging to the 74ACT logic family. It features eight non-inverting channels organized into two four-bit sections with independent output enable inputs. The device utilizes a TSSOP-20 surface-mount package and operates within a supply voltage range of 4.5 V to 5.5 V. Key electrical specifications include a maximum propagation delay of 9 ns at 5 V, high-level output current of -24 mA, low-level output current of 24 mA, and a static current of 4 uA. It supports a commercial operating temperature range from -40 °C to +85 °C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific RE4 suffix against the manufacturer's latest documentation to confirm it denotes an environmental compliance update rather than a functional change. Ensure the TSSOP-20 package dimensions match the design footprint requirements. Confirm RoHS status and lead-free composition details directly from the official datasheet before finalizing procurement specifications.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring high-density octal buffering with three-state control capabilities. It is suitable for interfaces demanding TTL input compatibility while maintaining CMOS output performance. Consider the 9 ns propagation delay and ±24 mA drive strength for signal integrity in standard digital logic environments.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74ACT244 series of octal buffers and drivers. The RE4 suffix typically indicates a specific manufacturing revision or environmental compliance variant within the standard SN74ACT244PWR product line. It shares core logical functionality with other variants in the ACT family but may differ in packaging or regulatory certifications.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The SN74ACT244PWR is a direct functional equivalent within the same series. Verify pinout compatibility and package dimensions (TSSOP-20) when substituting. Check if alternative revisions require any changes to external pull-up resistor configurations for the output enable pins.
