Specialized ICS Procurement Notes

Verify the specific suffix G against original manufacturer documentation to confirm exact manufacturing origin and compliance status. Rochester Electronics typically sources components from original manufacturers; ensure the datasheet aligns with the required electrical specifications for your design. Confirm RoHS compliance details directly with the supplier, as environmental declarations may vary based on production batch and sourcing channel. Cross-reference pinout assignments to prevent integration errors.

Specialized ICS Selection Notes

Select this component when an octal bidirectional transceiver with 7 ns speed is required for 5V logic systems. Ensure the application environment stays within the specified -40°C to +85°C temperature range. Verify that the 24 mA drive current meets the load requirements of the destination bus lines. Confirm that the TSSOP-20 package dimensions fit the PCB layout constraints and that the TTL input thresholds are compatible with the driving source signals.

Specialized ICS Part Context

This part belongs to the ACTQ series of advanced CMOS logic devices. It serves as a robust solution for connecting microprocessors to memory or peripheral devices. The octal configuration allows for efficient parallel data transmission across wide buses. The three-state outputs facilitate multiple drivers sharing a common communication line without signal contention.
