SN74LVC8T245DBRG4 Equivalent & Substitute Parts

Part Overview

The SN74LVC8T245DBRG4 is a translation transceiver logic IC manufactured by Texas Instruments, designed for 8-bit bidirectional signal translation in 3-state output configuration. This component operates across a wide supply voltage range of 1.65V to 5.5V and is housed in a 24-SSOP surface mount package. The part is currently discontinued at DiGi Electronics, making identification of equivalent and substitute parts essential for ongoing design support and production continuity.

Substitute Part Grouping Explanation

Substitution for the SN74LVC8T245DBRG4 is determined by strict equivalence across the following critical parameters:

• Logic Type: Translation Transceiver
• Number of Elements: 1
• Number of Bits per Element: 8
• Output Type: 3-State
• Current - Output High, Low: 32mA, 32mA
• Voltage - Supply: 1.65V ~ 5.5V
• Operating Temperature: -40°C ~ 85°C (TA)
• Package / Case: 24-SSOP (0.209", 5.30mm Width)
• Mounting Type: Surface Mount

Two substitute parts meet these criteria. Both are manufactured by Texas Instruments and maintain identical electrical and mechanical specifications. The primary distinction between substitutes is packaging format and product status.

Parameter Comparison

Engineering Selection Recommendations

Both SN74LVC8T245DBR and SN74LVCH8T245DBR are active, in-production alternatives to the discontinued SN74LVC8T245DBRG4. All three parts maintain identical electrical specifications and 24-SSOP package geometry, ensuring direct functional substitution.

SN74LVC8T245DBR is the primary substitute, offering the same 74LVC series designation with availability in both Cut Tape and Digi-Reel packaging formats. This part maintains full parametric equivalence and active product status.

SN74LVCH8T245DBR represents an alternative within the 74LVCH series variant. While belonging to a different series designation, it maintains all critical electrical and mechanical parameters required for substitution. This part demonstrates the highest inventory availability at 25,880 pieces.

Both substitutes carry ROHS3 compliance and REACH unaffected status, meeting regulatory requirements equivalent to the original part. Selection between these options should be based on packaging format requirements and supply chain availability.

Frequently Asked Questions (FAQ)

Q: Can SN74LVC8T245DBR directly replace SN74LVC8T245DBRG4 in existing designs?

A: Yes. Both parts are parametrically equivalent across all critical specifications: 8-bit translation transceiver, 3-state output, 32mA output current, 1.65V to 5.5V supply voltage range, -40°C to 85°C operating temperature, and 24-SSOP package geometry. The primary difference is product status and packaging format availability.

Q: What is the difference between SN74LVC8T245DBR and SN74LVCH8T245DBR?

A: Both parts maintain identical electrical and mechanical specifications. The distinction is series designation (74LVC versus 74LVCH) and packaging format. SN74LVC8T245DBR is available in Cut Tape and Digi-Reel formats, while SN74LVCH8T245DBR is supplied in Tape & Reel format. SN74LVCH8T245DBR demonstrates significantly higher inventory availability.

Q: Are there any compliance or regulatory differences between these parts?

A: No. All three parts are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity levels (MSL 1 - Unlimited). Regulatory status is equivalent across all options.

Q: Does the 24-SSOP package geometry remain consistent across all substitutes?

A: Yes. All parts use the 24-SSOP package with 0.209" width (5.30mm). PCB footprints and assembly processes remain unchanged.

Q: Which substitute should be selected for new production?

A: SN74LVC8T245DBR is recommended as the primary choice due to series continuity with the original part. SN74LVCH8T245DBR is a viable alternative when higher inventory availability or Tape & Reel packaging is required.
