Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify that the component matches the specific Philips Semiconductors product specification document dated January 16, 1998. Confirm the package designation corresponds to the 20-lead plastic dual in-line configuration. Ensure the ordering suffix aligns with the required temperature range and packaging format before finalizing procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a high-speed octal buffer with strong sink and source currents is required for system buses. The ABT technology offers superior speed compared to standard ALS or LSTTL families while maintaining compatibility with 5 V logic levels. Consider the physical layout benefits provided by the opposing input/output pin arrangement.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74ABT family of high-performance BiCMOS logic devices. It functions similarly to the 'ABT241 but features non-inverting logic. The device is manufactured under the Philips Semiconductors brand, which is now part of NXP USA Inc., representing a transition in corporate ownership while maintaining the original technical specifications.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The datasheet notes functional similarity to the 'ABT241. Verify pinout compatibility if substituting with other octal buffers in the 74ABT series. Ensure any replacement maintains the same 20-pin DIP footprint and electrical ratings.
