SN74LVC1G00IDCKREP NAND Gate IC Equivalent & Substitute Parts

Part Overview

The SN74LVC1G00IDCKREP is a single-channel 2-input NAND gate logic IC manufactured by Texas Instruments, packaged in SC-70-5 (5-TSSOP) configuration. This component operates across a wide supply voltage range of 1.65V to 5.5V and is classified as an active product with ROHS3 compliance. Substitute parts are identified based on functional equivalence as single-channel 2-input NAND gates with compatible electrical characteristics and surface-mount packaging options. Alternative sources become necessary for inventory availability, extended temperature ranges, or specific packaging preferences while maintaining circuit functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SN74LVC1G00IDCKREP is determined by the following criteria:

Functional Requirements:

• Logic Type: NAND Gate (single channel, 2-input configuration)
• Number of Circuits: 1
• Number of Inputs: 2

Electrical Compatibility:

• Supply Voltage Range: Minimum 1.65V support required; maximum 5.5V or higher acceptable
• Output Current Capability: 32mA minimum for both high and low states
• Propagation Delay: Maximum 4.3ns at 5V with 50pF load

Physical & Environmental Compatibility:

• Mounting Type: Surface Mount only
• Package Options: 5-TSSOP, SC-70-5, or SOT-353 equivalent footprints
• Operating Temperature: Minimum -40°C; maximum 85°C or extended range acceptable
• Compliance: ROHS3 compliant preferred; RoHS compliant acceptable

All identified substitutes meet these core criteria while offering variations in quiescent current, propagation delay, temperature range, and packaging format.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (Identical Operating Temperature Range):

74LVCE1G00SE-7 and NC7SZ00P5X are functionally equivalent to the SN74LVC1G00IDCKREP within the -40°C to 85°C operating window. Both maintain ROHS3 compliance and identical output current specifications. The 74LVCE1G00SE-7 offers improved propagation delay (3.6ns vs 4ns) and lower minimum supply voltage (1.4V vs 1.65V). The NC7SZ00P5X provides superior quiescent current performance (2 µA vs 10 µA).

Extended Temperature Range Substitutes:

74LVC1G00SE-7, NL17SZ00DFT2G, and 74LVC1G00GW,125 extend the maximum operating temperature to 125°C while maintaining full electrical compatibility. The NL17SZ00DFT2G offers the lowest quiescent current (1 µA) and widest temperature range (-55°C to 125°C). The 74LVC1G00GW,125 provides the lowest quiescent current among the 74LVC series (4 µA) with extended temperature capability.

Packaging Considerations:

TC7SZ00F(TE85L,JF) uses SC-74A/SOT-753 packaging, which differs from the standard 5-TSSOP footprint. This part is suitable only for designs already accommodating this package format. TC7SZ00FU,LJ(CT maintains standard 5-TSSOP compatibility.

Compliance & Availability:

All substitute parts maintain ROHS3 compliance and active product status. Inventory levels vary significantly, with NL17SZ00DFT2G (125,400 pcs) and NC7SZ00P5X (173,200 pcs) offering the highest availability.

Frequently Asked Questions (FAQ)

Q: Can I use 74LVC1G00SE-7 as a direct replacement for SN74LVC1G00IDCKREP?

A: Yes. Both are single-channel 2-input NAND gates with identical supply voltage range (1.65V ~ 5.5V), output current (32mA), and package compatibility (5-TSSOP/SC-70-5/SOT-353). The 74LVC1G00SE-7 offers faster propagation delay (1.8ns vs 4ns) and extended temperature range (-40°C to 125°C vs -40°C to 85°C). Higher quiescent current (200 µA vs 10 µA) may impact low-power applications.

Q: What is the difference between 74LVCE1G00SE-7 and 74LVC1G00SE-7?

A: The 74LVCE1G00SE-7 operates at lower minimum supply voltage (1.4V vs 1.65V) and exhibits faster propagation delay (3.6ns vs 1.8ns). Both maintain identical output current and package specifications. The 74LVCE variant is suitable for ultra-low-voltage applications.

Q: Which substitute offers the best power efficiency?

A: NL17SZ00DFT2G provides the lowest quiescent current at 1 µA maximum, followed by NC7SZ00P5X and TC7SZ series at 2 µA. For applications prioritizing minimal standby power consumption, NL17SZ00DFT2G is the optimal choice.

Q: Are all substitutes available in the same package?

A: Most substitutes use 5-TSSOP/SC-70-5/SOT-353 packaging. TC7SZ00F(TE85L,JF) is the exception, using SC-74A/SOT-753 packaging. Verify PCB footprint compatibility before selection.

Q: Can I use TC7SZ series parts in designs requiring -40°C operation?

A: Yes. TC7SZ00F(TE85L,JF) and TC7SZ00FU,LJ(CT both operate from -40°C to 85°C. However, minimum supply voltage is 1.8V (vs 1.65V for 74LVC series), which may affect ultra-low-voltage circuit designs.

Q: What is the inventory status for high-volume procurement?

A: NL17SZ00DFT2G (125,400 pcs), NC7SZ00P5X (173,200 pcs), and 74LVCE1G00SE-7 (93,100 pcs) offer substantial stock levels. SN74LVC1G00IDCKREP (2,410 pcs) and TC7SZ00F(TE85L,JF) (1,167 pcs) have limited availability.
