Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'E4' indicates lead-free composition and RoHS compliance as per Texas Instruments documentation. Confirm the package type matches the required 20-SOIC footprint for PCB layout. Ensure the operating temperature grade aligns with system environmental requirements. Cross-reference the datasheet revision date to confirm current electrical characteristics and ordering information.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when interfacing between systems requiring octal buffering with three-state isolation. The HCT series ensures voltage level compatibility with older TTL devices. Consider the SOIC package size for space-constrained designs. Verify that the drive current capabilities meet the load requirements of the connected circuitry without exceeding absolute maximum ratings.
