SN74LVC1G08MDCKREP Equivalent & Substitute Parts

Part Overview

The SN74LVC1G08MDCKREP is a single-channel 2-input AND gate logic IC manufactured by Texas Instruments in SC-70-5 packaging. This component is classified as Active product status and is currently in stock with 4,120 units available. The 74LVC1G08 series operates across a wide supply voltage range of 1.65V to 5.5V, making it suitable for both legacy and modern low-voltage digital applications. Substitute parts are necessary when SC-70-5 packaging availability is limited, when alternative manufacturers are preferred for supply chain optimization, or when specific performance characteristics such as propagation delay or quiescent current are critical to application requirements.

Substitute Part Grouping Explanation

Substitute parts for the SN74LVC1G08MDCKREP are qualified based on the following criteria:

Functional Equivalence: All substitute parts maintain identical logic function (single-channel 2-input AND gate), circuit count, and input configuration.

Electrical Compatibility: Supply voltage range, output current capability (32mA high and low), and logic family (74LVC or 74LVCE series) must be compatible with the original specification.

Package Compatibility: Substitute parts must use equivalent surface-mount packages within the 5-TSSOP, SC-70-5, or SOT-353 family to ensure PCB footprint compatibility.

Performance Parameters: Propagation delay and quiescent current are secondary selection criteria when primary electrical and package requirements are met.

Compliance Requirements: All substitute parts must maintain ROHS3 compliance and MSL Level 1 rating to match the original part's environmental and regulatory status.

The following substitute parts meet these criteria across multiple manufacturers including Nexperia USA Inc., Diodes Incorporated, onsemi, and Toshiba Semiconductor and Storage.

Engineering Selection Recommendations

Direct Package Match (Recommended for PCB Compatibility): The 74LVC1G08GW,125 (Nexperia) and 74LVC1G08SE-7 (Diodes) are direct substitutes with identical 5-TSSOP packaging to the SN74LVC1G08MDCKREP. Both maintain full electrical compatibility, ROHS3 compliance, and MSL Level 1 rating. The 74LVC1G08GW,125 offers improved quiescent current performance (4 µA vs. 10 µA) and faster propagation delay (4ns vs. 5ns). The 74LVC1G08SE-7 provides the fastest propagation delay (1.7ns) but with elevated quiescent current (200 µA).

Alternative Package Option: The 74LVC1G08GV,125 (Nexperia) uses SC-74A packaging instead of SC-70-5, requiring PCB footprint verification before selection. This part offers the same electrical performance as the 74LVC1G08GW,125 variant.

Extended Temperature Range: The NLV17SZ08DFT2G (onsemi) maintains the original -55°C to 125°C operating temperature range and offers the lowest quiescent current (1 µA). However, this part is classified as Obsolete product status and should be selected only when extended temperature performance is mandatory and availability can be confirmed.

Active Status Priority: For new designs and ongoing production, select from parts with Active product status: 74LVC1G08GW,125, 74LVC1G08GV,125, 74LVC1G08SE-7, 74LVCE1G08SE-7, or TC7SZ08FU,LJ(CT.

Supply Voltage Consideration: The 74LVCE1G08SE-7 (Diodes) supports a lower minimum supply voltage (1.4V vs. 1.65V), making it suitable for ultra-low-voltage applications. Operating temperature is limited to -40°C to 85°C.

Minimum Supply Voltage Limitation: The TC7SZ08FU,LJ(CT (Toshiba) has a minimum supply voltage of 1.8V, which is higher than the original specification. This part is suitable only for applications where the supply voltage remains above 1.8V.

Frequently Asked Questions (FAQ)

Q: Can I use 74LVC1G08GV,125 as a direct replacement for SN74LVC1G08MDCKREP?

A: The 74LVC1G08GV,125 is electrically equivalent but uses SC-74A packaging instead of SC-70-5. PCB footprint compatibility must be verified before substitution. If your PCB is designed for SC-70-5, use 74LVC1G08GW,125 or 74LVC1G08SE-7 instead.

Q: What is the difference between 74LVC1G08GW,125 and 74LVC1G08SE-7?

A: Both use 5-TSSOP packaging compatible with the original part. The 74LVC1G08GW,125 (Nexperia) has lower quiescent current (4 µA) and standard propagation delay (4ns). The 74LVC1G08SE-7 (Diodes) has higher quiescent current (200 µA) but faster propagation delay (1.7ns). Select based on power consumption or speed requirements.

Q: Is NLV17SZ08DFT2G suitable for new designs?

A: The NLV17SZ08DFT2G is classified as Obsolete product status. While it offers excellent performance characteristics (1 µA quiescent current, -55°C to 125°C operating range), it should not be selected for new designs. Use Active status parts instead.

Q: Can I substitute TC7SZ08FU,LJ(CT for the original part in all applications?

A: The TC7SZ08FU,LJ(CT has a minimum supply voltage of 1.8V, which exceeds the original specification of 1.65V. This part is suitable only for applications where supply voltage remains above 1.8V. Verify your circuit's minimum operating voltage before selection.

Q: Are all substitute parts ROHS3 compliant?

A: Yes, all listed substitute parts maintain ROHS3 compliance and MSL Level 1 rating, matching the environmental and regulatory status of the original SN74LVC1G08MDCKREP.

Q: Which substitute offers the best power efficiency?

A: The NLV17SZ08DFT2G offers the lowest quiescent current (1 µA), followed by TC7SZ08FU,LJ(CT (2 µA). For Active status parts, 74LVC1G08GV,125 and 74LVC1G08GW,125 both offer 4 µA quiescent current.

Q: What is the difference between 74LVCE1G08SE-7 and 74LVC1G08SE-7?

A: The 74LVCE1G08SE-7 belongs to the 74LVCE series with extended low-voltage capability (1.4V minimum supply) but limited operating temperature range (-40°C to 85°C). The 74LVC1G08SE-7 is standard 74LVC series with 1.65V minimum supply and -40°C to 125°C operating range. Select based on your minimum supply voltage and temperature requirements.
