Key Parameters

Substitute Part Grouping Explanation

Substitution of the SN74LVC1G32DRLRG4 is determined by the following critical parameters:

• Logic function: Single-channel, 2-input OR gate
• Supply voltage range: 1.65V ~ 5.5V
• Output drive capability: 32mA minimum for both high and low states
• Package compatibility: SOT-553 surface mount
• Regulatory compliance: ROHS3 and REACH requirements

All identified substitute parts maintain these core electrical and mechanical specifications, ensuring functional equivalence in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

SN74LVC1G32DRLR (Texas Instruments): Direct parametric equivalent with identical electrical specifications and active product status. Recommended as primary substitute for design continuity within the Texas Instruments 74LVC series. Higher inventory availability (29,200 pcs) supports production requirements.

NL17SZ32XV5T2G (onsemi): Functionally equivalent with superior quiescent current performance (1 µA vs. 10 µA) and extended lower operating temperature limit (-55°C). Suitable for applications requiring reduced power consumption or expanded temperature range. Highest inventory availability (85,100 pcs).

TC7SZ32FE,LJ(CT (Toshiba Semiconductor and Storage): Functionally equivalent with reduced quiescent current (2 µA) and faster propagation delay (4.3ns). Operating temperature upper limit restricted to 85°C; verify compatibility with application thermal requirements. Lower inventory (8,215 pcs).

All substitutes maintain ROHS3 compliance and SOT-553 package compatibility, ensuring direct PCB layout compatibility.

Frequently Asked Questions (FAQ)

Q: Can SN74LVC1G32DRLR replace SN74LVC1G32DRLRG4 without circuit modification?

A: Yes. Both parts are parametrically identical with matching supply voltage range (1.65V ~ 5.5V), output drive capability (32mA), and propagation delay (4ns @ 5V, 50pF). SOT-553 package pinout is identical. No circuit changes required.

Q: What is the primary difference between the onsemi NL17SZ32XV5T2G and the original part?

A: The NL17SZ32XV5T2G maintains all critical electrical parameters but offers lower quiescent current (1 µA vs. 10 µA) and extended lower operating temperature (-55°C vs. -40°C). Propagation delay is marginally higher (4.5ns vs. 4ns). These differences do not affect functional compatibility in standard logic applications.

Q: Is the Toshiba TC7SZ32FE,LJ(CT suitable for high-temperature applications?

A: The TC7SZ32FE,LJ(CT operating temperature range is -40°C to 85°C, which is more restrictive than the original part (-40°C to 125°C). Verify application maximum operating temperature before selection. For applications requiring operation above 85°C, use SN74LVC1G32DRLR or NL17SZ32XV5T2G.

Q: Are all substitute parts available in the same packaging format?

A: All substitute parts use SOT-553 package. Verify supplier packaging options (Cut Tape, Digi-Reel, Tape & Reel) match your procurement and assembly requirements.

Q: Do all parts meet the same regulatory compliance standards?

A: Yes. All listed parts are ROHS3 compliant and REACH unaffected, meeting equivalent regulatory requirements for industrial and commercial applications.
