Specialty Logic Procurement Notes

Verify the specific suffix 'DLR' corresponds to the SSOP-48 package and reel packaging configuration. Confirm that the 4.5V to 5.5V operating voltage aligns with the target system power rails. Ensure the industrial temperature grade meets environmental requirements. Cross-reference the manufacturer part number against current datasheets to validate pinout compatibility before integration into new designs.

Specialty Logic Selection Notes

Select this component when designing systems requiring strict adherence to IEEE Std 1284 specifications. It is suitable for applications needing a 19-bit wide interface with reliable performance at 5V logic levels. Consider the SSOP-48 footprint constraints during PCB layout planning. Evaluate thermal management needs given the specified operating temperature range and typical current consumption characteristics.

Specialty Logic Part Context

This device belongs to the SN74LV series of low-voltage CMOS logic components. It serves as a specialized interface solution rather than a general-purpose logic gate. The part complements other Texas Instruments interface products by providing standardized parallel communication capabilities. It addresses the need for reliable data transfer in legacy and modern parallel bus architectures.

Specialty Logic Replacement Considerations

SN74LVC161284DLR offers similar functionality but operates at lower voltage levels (3V to 3.6V). Verify voltage compatibility before substitution. SN74LV161284DGGR provides the same electrical characteristics in a TSSOP-48 package, requiring footprint adaptation.
