SN74LV14ADRG4 Equivalent & Substitute Parts

Part Overview

The SN74LV14ADRG4 is a 6-channel inverter IC with Schmitt trigger inputs manufactured by Texas Instruments in a 14-SOIC surface mount package. This part is discontinued at DiGi Electronics, making equivalent and substitute parts necessary for ongoing design support and procurement. The device operates across a 2V to 5.5V supply voltage range and is suitable for logic signal inversion applications requiring hysteresis input characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the SN74LV14ADRG4 is determined by the following criteria:

Functional Requirements:

• Logic Type: Inverter with 6 channels and Schmitt trigger inputs
• Package: 14-SOIC surface mount form factor
• Pin compatibility: 1 input per channel configuration

Electrical Compatibility:

• Supply voltage range must encompass or match 2V ~ 5.5V
• Input logic levels must be compatible with system signal levels
• Output current capability must meet or exceed 12mA per channel
• Propagation delay characteristics must be acceptable for timing-critical applications

Compliance & Status:

• RoHS3 compliance required
• MSL rating of 1 (Unlimited) preferred
• Active product status preferred due to discontinued status of main part

Substitute parts are grouped by manufacturer recommendation level and parametric equivalence based on these criteria.

Parameter Comparison

Engineering Selection Recommendations

SN74LV14ADR (Texas Instruments) - Recommended as primary substitute. Identical electrical specifications to the main part with active product status. Same manufacturer ensures consistency in design documentation and supply chain continuity. 5300 units in stock.

74LV14AS14-13 (Diodes Incorporated) - Parametric equivalent with identical electrical characteristics to the main part. Active product status with highest inventory availability at 15100 units. Suitable for direct replacement in applications where manufacturer diversity is acceptable.

74LV14D,118 (Nexperia USA Inc.) - MFR recommended substitute with active status and 8189 units in stock. Extended supply voltage range (1V ~ 5.5V) provides additional design flexibility. Higher quiescent current (40 µA max) and slightly longer propagation delay (15ns @ 3.3V) require evaluation for power-sensitive or timing-critical applications.

MC74LVX14DR2G (onsemi) - Direct manufacturer alternative with active status. Reduced supply voltage range (2V ~ 3.6V) limits applicability to 3.3V and lower systems. Lower output current (4mA) and higher propagation delay (14.1ns @ 3.3V) restrict use to applications with reduced drive requirements. Lower quiescent current (2 µA) beneficial for battery-powered designs. 1139 units in stock.

All substitute parts maintain ROHS3 compliance and MSL rating of 1 (Unlimited), ensuring compatibility with standard manufacturing and storage requirements.

Frequently Asked Questions (FAQ)

Q: Can SN74LV14ADR be used as a direct replacement for SN74LV14ADRG4?

A: Yes. SN74LV14ADR is electrically and functionally identical to SN74LV14ADRG4 with matching supply voltage range, input/output logic levels, propagation delay, and output current specifications. Both use 14-SOIC packaging. The primary difference is product status: SN74LV14ADR is active while SN74LV14ADRG4 is discontinued.

Q: What are the key differences between the 74LV and 74LVX series substitutes?

A: The 74LVX series (MC74LVX14DR2G) operates at a reduced supply voltage range of 2V ~ 3.6V compared to 2V ~ 5.5V for 74LV devices. The 74LVX variant also provides lower output current (4mA vs 12mA) and lower quiescent current (2 µA vs 20 µA). Selection depends on system voltage requirements and drive capability needs.

Q: Are all substitute parts pin-compatible with the original SN74LV14ADRG4?

A: Yes. All listed substitutes use the 14-SOIC package with identical pinout for 6-channel inverter with Schmitt trigger inputs. Physical and electrical pin compatibility is maintained across all alternatives.

Q: Which substitute offers the best inventory availability?

A: 74LV14AS14-13 from Diodes Incorporated has the highest inventory at 15100 units in stock, followed by 74LV14D,118 from Nexperia at 8189 units.

Q: Can MC74LVX14DR2G be used in 5V applications?

A: No. MC74LVX14DR2G operates within a 2V ~ 3.6V supply voltage range and is not rated for 5V operation. Use only in 3.3V or lower voltage systems.

Q: What is the impact of propagation delay differences between substitutes?

A: Propagation delay varies from 10.6ns (SN74LV14ADR, 74LV14AS14-13 @ 5V, 50pF) to 15ns (74LV14D,118 @ 3.3V, 50pF). For timing-critical applications, verify that the substitute's propagation delay meets system timing requirements. Longer delays may affect signal edge rates and system synchronization.

Q: Are all substitutes RoHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and MSL rating of 1 (Unlimited), meeting standard environmental and manufacturing requirements.
