SN74ALVC14DRG4 Equivalent & Substitute Parts

Part Overview

The SN74ALVC14DRG4 is a 6-channel inverter IC with Schmitt trigger inputs manufactured by Texas Instruments in a 14-SOIC surface mount package. This device is discontinued at DiGi Electronics, making equivalent substitute parts necessary for ongoing production and maintenance applications. The part operates across a 2.3V to 3.6V supply voltage range with low quiescent current and fast propagation delay characteristics suitable for logic signal conditioning and inversion applications.

Substitute Part Grouping Explanation

Substitution for the SN74ALVC14DRG4 is determined by strict equivalence across the following parameters: logic type (inverter), circuit count (6 channels), input count (1 per channel), Schmitt trigger feature, supply voltage range (2.3V ~ 3.6V), quiescent current specification (10 µA max), output current capability (24mA), input logic thresholds, propagation delay (3.4ns @ 3.3V, 50pF), operating temperature range (-40°C ~ 85°C), and package type (14-SOIC). Substitute parts must maintain identical electrical performance and physical compatibility with the original design.

Engineering Selection Recommendations

The SN74ALVC14DR is a parametric equivalent manufactured by Texas Instruments with identical electrical specifications and package configuration. This part maintains active product status and is available in higher inventory quantities (2136 pcs) compared to the discontinued SN74ALVC14DRG4. Both parts are ROHS3 compliant with MSL 1 rating.

The 74ALVC14D,118 manufactured by NXP Semiconductors is listed as a manufacturer-recommended substitute with active product status and substantial inventory availability (6603 pcs). However, complete electrical parameter specifications are not provided in the available documentation. Selection of this part requires verification against the full NXP datasheet to confirm equivalence across all critical parameters including supply voltage range, quiescent current, output current, input logic thresholds, and propagation delay.

Frequently Asked Questions (FAQ)

Q: Can the SN74ALVC14DR directly replace the SN74ALVC14DRG4?

A: Yes. Both parts are manufactured by Texas Instruments with identical electrical specifications, Schmitt trigger functionality, 6-channel inverter configuration, 14-SOIC package, and operating parameters. The primary difference is packaging format: SN74ALVC14DRG4 is supplied in Tape & Reel (TR) while SN74ALVC14DR is supplied in Cut Tape (CT) & Digi-Reel format.

Q: What is the difference between the packaging formats?

A: Tape & Reel (TR) packaging is optimized for high-volume automated assembly lines, while Cut Tape (CT) & Digi-Reel packaging is suitable for lower-volume production and component distribution. Both formats contain identical components in the same 14-SOIC package.

Q: Is the 74ALVC14D,118 from NXP a direct equivalent?

A: The 74ALVC14D,118 is listed as a manufacturer-recommended substitute and shares the same base product number (74ALVC14) and core inverter functionality. However, complete electrical parameter documentation is not provided. Confirmation of full parameter equivalence requires consultation of the NXP datasheet before design implementation.

Q: What are the critical parameters for substitution?

A: Substitution equivalence is determined by: 6-channel inverter configuration, Schmitt trigger input feature, 2.3V to 3.6V supply voltage range, 10 µA maximum quiescent current, 24mA output current capability, specified input logic thresholds, 3.4ns propagation delay at 3.3V with 50pF load, -40°C to 85°C operating temperature range, and 14-SOIC surface mount package.

Q: Are all substitute parts ROHS3 compliant?

A: The SN74ALVC14DR is confirmed ROHS3 compliant with MSL 1 rating. The 74ALVC14D,118 has MSL 1 rating confirmed, but ROHS status is not specified in the available data.
