SN74HCT244DWRG4

Buffers, Drivers, Receivers, Transceivers Overview

The SN74HCT244DWRG4 is an octal buffer and line driver manufactured by Texas Instruments, belonging to the HCT logic family. It features eight non-inverting outputs with three-state capability, organized into two independent four-bit sections. Each section includes a separate output enable (OE) input for bus management. The device operates within a supply voltage range of 4.5 V to 5.5 V. It provides high current drive capabilities, supporting up to 6 mA low-level and -6 mA high-level output currents. The component is housed in a 20-pin SOIC package and supports surface-mount installation.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix G4 confirms RoHS compliance and green manufacturing status as per Texas Instruments standards. Ensure the SOIC-20 package dimensions match the target PCB footprint requirements. Confirm that the HCT logic family characteristics align with the system's voltage levels and noise immunity needs before finalizing procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring high-density octal buffering with three-state isolation. The HCT technology ensures compatibility with TTL inputs while maintaining CMOS performance. Consider the 20-pin SOIC package for space-constrained applications. Verify that the 4.5 V to 5.5 V operating range matches the system power supply specifications.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74HCT244 series of octal buffers and line drivers. The series is designed to improve performance and density in digital systems.
