Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the ordering suffix ',112' corresponds to the TSSOP-20 package configuration as specified in the datasheet. Confirm that the manufacturer designation aligns with Philips Semiconductors or NXP legacy documentation standards. Ensure compatibility with the recommended operating conditions regarding supply voltage limits and temperature ranges before procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring octal buffering with built-in series termination to minimize signal reflections. It serves as a direct replacement for the 74ABT244-1 part number. Consider the TSSOP-20 package constraints if space is limited. Verify input transition rates do not exceed the specified limits to maintain timing accuracy.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the 74ABT logic family, characterized by BiCMOS technology offering low static and dynamic power dissipation combined with high speed. It is functionally identical to the 74ABT244-1, with the naming change reflecting industry standardization. The product specification supersedes data from October 1996.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The 74ABT2244 is explicitly identified as the same part as the 74ABT244-1. Substitution should verify package compatibility, specifically the TSSOP-20 form factor for the PW suffix.

Buffers, Drivers, Receivers, Transceivers FAQ

Is the 74ABT2244 compatible with the 74ABT244?

Yes, the datasheet states the 74ABT2244 is the same part as the 74ABT244-1, with the name changed to reflect industry standards.
