Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'G4' against manufacturer documentation to confirm RoHS compliance status and lead-free manufacturing details. Ensure the SOIC-24 footprint matches the target PCB design constraints. Cross-reference the datasheet revision history to validate electrical characteristics against the intended operating temperature range of -40°C to +85°C.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal transceiver requires internal data registration to synchronize bus transfers. The ABT logic series offers superior speed compared to standard LS or ALS families while maintaining compatible voltage levels. Verify that the required drive current exceeds 32 mA for high states and 64 mA for low states to ensure signal integrity across the bus load.
