SN74LVC1G98IDCKREP Equivalent & Substitute Parts

Part Overview

The SN74LVC1G98IDCKREP is a configurable multiple function gate logic IC manufactured by Texas Instruments, designed for low-voltage applications requiring flexible logic configuration. This single-circuit, three-input device operates across a wide supply voltage range of 1.65V to 5.5V and is housed in a compact SC-70-6 package. The part is currently in active production status with 1130 units available in inventory. Substitute parts are necessary when the primary part becomes unavailable, when alternative packaging formats are required for manufacturing processes, or when enhanced operating temperature ranges are needed for specific application environments.

Substitute Part Grouping Explanation

Substitute parts for the SN74LVC1G98IDCKREP are qualified based on the following critical parameters that determine functional and mechanical compatibility:

• Logic Type: Configurable Multiple Function (must match)
• Number of Circuits: 1 (must match)
• Number of Inputs: 3 (must match)
• Output Type: Single-Ended (must match)
• Current - Output High, Low: 32mA, 32mA (must match)
• Voltage - Supply: 1.65V ~ 5.5V (must match)
• Package / Case: 6-TSSOP, SC-88, SOT-363 (must be compatible)
• Mounting Type: Surface Mount (must match)
• RoHS Status: ROHS3 Compliant (must match)

The identified substitute parts maintain these core electrical and mechanical specifications while potentially offering variations in operating temperature range, Schmitt trigger input capability, or product status. All substitutes are housed in compatible package formats suitable for the same PCB assembly processes.

Parameter Comparison

Engineering Selection Recommendations

The 74LVC1G98DW-7 manufactured by Diodes Incorporated is the primary recommended substitute for the SN74LVC1G98IDCKREP. Both parts maintain active product status, ensuring long-term availability and manufacturing support. The 74LVC1G98DW-7 extends the upper operating temperature limit to 125°C compared to the original part's 85°C maximum, providing enhanced thermal performance for demanding applications. Both parts are ROHS3 compliant and carry identical electrical specifications.

The NL7SZ98DFT2G from onsemi is a functional equivalent that meets all core electrical and mechanical requirements. However, this part carries an obsolete product status, indicating it is no longer in active production. The NL7SZ98DFT2G incorporates Schmitt trigger input capability and supports an extended operating temperature range of -55°C to 125°C, making it suitable for applications requiring enhanced noise immunity or extreme temperature operation. Current inventory availability is significantly higher at 105,200 units.

For applications requiring active product status and long-term supply assurance, the 74LVC1G98DW-7 is the preferred selection. For applications where extended temperature performance or Schmitt trigger functionality is required and obsolete part status is acceptable, the NL7SZ98DFT2G remains electrically compatible.

Frequently Asked Questions (FAQ)

Q: Can the NL7SZ98DFT2G be used as a direct replacement for the SN74LVC1G98IDCKREP?

A: Yes, the NL7SZ98DFT2G is electrically and mechanically compatible. All core parameters including logic type, circuit count, input count, output current, and supply voltage are identical. The part is housed in the same package family (SC-88/SC70-6/SOT-363). However, the NL7SZ98DFT2G carries obsolete product status, meaning it is no longer manufactured.

Q: What is the difference between the Schmitt trigger input versions?

A: The SN74LVC1G98IDCKREP and 74LVC1G98DW-7 do not include Schmitt trigger input capability. The NL7SZ98DFT2G includes Schmitt trigger input, which provides hysteresis for improved noise immunity on input signals. This is an additional feature that does not affect basic substitution compatibility.

Q: Are all three parts compatible with the same PCB layout?

A: Yes. All three parts use compatible package formats within the 6-TSSOP, SC-88, SOT-363 family. Surface mount assembly processes are identical across all three parts. No PCB redesign is required for substitution.

Q: Which substitute part should be selected for new designs?

A: The 74LVC1G98DW-7 is recommended for new designs due to its active product status, ensuring availability throughout the product lifecycle. The extended operating temperature range to 125°C provides additional design margin for thermal performance.

Q: What is the inventory status of each part?

A: The SN74LVC1G98IDCKREP has 1,130 units in stock. The 74LVC1G98DW-7 has 9,100 units available. The NL7SZ98DFT2G has 105,200 units in inventory, though this part is obsolete.

Q: Are all parts RoHS compliant?

A: Yes. All three parts are ROHS3 compliant and carry REACH unaffected status, meeting environmental and regulatory requirements for commercial and industrial applications.
