74ALVC245D,112 Equivalent & Substitute Parts

Part Overview

The 74ALVC245D,112 is a non-inverting transceiver logic IC manufactured by Nexperia USA Inc., designed for 8-bit bidirectional data transfer with 3-state output capability. Operating across a supply voltage range of 1.65V to 3.6V, this component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations.

The 74ALVC series provides low-voltage transceiver functionality suitable for mixed-signal applications requiring level translation and bus buffering. Due to its obsolete status, direct substitutes from active product lines are necessary to maintain design continuity and ensure component availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 74ALVC245D,112 is determined by strict equivalence across the following critical parameters:

Functional Parameters:

• Logic type: Transceiver, Non-Inverting
• Number of elements: 1
• Bits per element: 8
• Output configuration: 3-State

Electrical Parameters:

• Supply voltage range: 1.65V ~ 3.6V
• Output current capability: 24mA (high and low)
• Operating temperature range: -40°C ~ 85°C

Physical Parameters:

• Package type: 20-SOIC (0.295", 7.50mm Width)
• Mounting type: Surface Mount

Compliance Parameters:

• RoHS3 Compliant
• MSL Level 1

Substitute parts are grouped into two categories based on series designation: 74ALVC series (direct base product equivalents) and 74ALVCH series (enhanced variant with identical electrical and mechanical specifications). All substitutes maintain identical parametric performance and package footprint compatibility.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts are active products from Texas Instruments and maintain full parametric equivalence with the obsolete 74ALVC245D,112. Selection among substitutes should be based on packaging and supply chain requirements:

SN74ALVC245DWR and SN74ALVCH245DWR are supplied in Tape & Reel (TR) format, suitable for high-volume automated assembly operations. Both maintain identical electrical specifications and 20-SOIC package footprint.

SN74ALVC245DW and SN74ALVCH245DW are supplied in Tube packaging, appropriate for lower-volume applications or manual assembly processes. These variants provide the same functional and electrical performance as their tape-and-reel counterparts.

The 74ALVC and 74ALVCH series designations indicate different product lines within Texas Instruments' transceiver portfolio. Both series meet all compliance requirements (ROHS3, MSL Level 1) and operate within identical electrical parameters. Selection between series should be based on availability and supply chain continuity rather than functional differences, as all electrical and mechanical specifications are equivalent.

Frequently Asked Questions (FAQ)

Q: Can SN74ALVC245DWR directly replace 74ALVC245D,112 in existing designs?

A: Yes. The SN74ALVC245DWR maintains identical electrical specifications, output current ratings (24mA), supply voltage range (1.65V ~ 3.6V), operating temperature range (-40°C ~ 85°C), and 20-SOIC package footprint. The only difference is packaging format (Tape & Reel vs. original packaging) and active product status.

Q: What is the difference between 74ALVC and 74ALVCH series substitutes?

A: Both series provide identical functional and electrical performance for this application. The 74ALVCH designation indicates an enhanced variant within the Texas Instruments product line, but all critical parameters—logic type, bit width, output current, supply voltage, temperature range, and package—are equivalent. Selection should be based on component availability.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitutes (SN74ALVC245DWR, SN74ALVCH245DWR, SN74ALVC245DW, SN74ALVCH245DW) are ROHS3 Compliant with MSL Level 1 (Unlimited), matching the compliance profile of the original 74ALVC245D,112.

Q: Does packaging format (Tape & Reel vs. Tube) affect electrical performance?

A: No. Packaging format affects only supply chain logistics and assembly process compatibility. Tape & Reel (TR) format is optimized for automated pick-and-place assembly, while Tube format is suitable for manual handling and lower-volume applications. Electrical specifications and package footprint remain identical.

Q: Can I use SN74ALVC245DW instead of SN74ALVC245DWR?

A: Yes. Both parts are functionally and electrically equivalent. The difference is packaging: DWR is supplied in Tape & Reel format, while DW is supplied in Tube format. Select based on your assembly process requirements and supply chain availability.

Q: What is the 20-SOIC package specification?

A: The 20-SOIC (Small Outline Integrated Circuit) package measures 0.295 inches (7.50mm) in width. This is a surface-mount package with 20 pins, maintaining identical footprint compatibility across all listed substitutes.
