74AVC4T774RGYRG4 Equivalent & Substitute Parts

Part Overview

The 74AVC4T774RGYRG4 is a voltage level translator IC from Texas Instruments, designed for bidirectional signal translation across different voltage domains. This device features 1 circuit with 4 bidirectional channels, supporting data rates up to 380 Mbps, and operates across voltage ranges of 1.1 V to 3.6 V on both VCCA and VCCB supplies. The part is packaged in a 16-VQFN (4x4.6) surface mount configuration with exposed pad.

The 74AVC4T774RGYRG4 is currently discontinued at DiGi Electronics. Identifying equivalent substitute parts is necessary to maintain design continuity and ensure project timelines are not disrupted due to component unavailability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 74AVC4T774RGYRG4 is determined by strict equivalence across the following critical parameters:

• Translator Type & Channel Configuration: Voltage level translator with bidirectional, 1 circuit, 4-channel architecture
• Voltage Specifications: VCCA and VCCB operating ranges of 1.1 V to 3.6 V
• Signal Characteristics: Tri-state, non-inverted output with 380 Mbps data rate capability
• Physical Package: 16-VFQFN exposed pad surface mount configuration
• Electrical Compliance: ROHS3 compliance and MSL 2 rating

The SN74AVC4T774RGYR meets all these criteria and is classified as a parametric equivalent. Both parts share identical electrical specifications, package geometry, and functional performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The SN74AVC4T774RGYR is the direct parametric equivalent for the discontinued 74AVC4T774RGYRG4. Both parts are manufactured by Texas Instruments and maintain identical electrical specifications, package geometry, and functional performance.

The primary distinction is product status: the 74AVC4T774RGYRG4 is discontinued, while the SN74AVC4T774RGYR remains in active production with significantly higher inventory availability (23,100 pieces versus 840 pieces). Both parts carry ROHS3 compliance and identical MSL ratings, ensuring regulatory and environmental compatibility.

For new designs or component replenishment, the SN74AVC4T774RGYR is the appropriate selection due to its active status and sustained supply chain availability.

Frequently Asked Questions (FAQ)

Q: Are the 74AVC4T774RGYRG4 and SN74AVC4T774RGYR pin-compatible?
