74ALVC245MTC Equivalent & Substitute Parts

Part Overview

The 74ALVC245MTC is a non-inverting transceiver logic IC manufactured by onsemi, 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. Due to its discontinued status, equivalent and substitute parts from active manufacturers are necessary for new designs and ongoing production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the 74ALVC245MTC is determined by the following critical parameters:

• Logic Type: Transceiver, Non-Inverting
• Number of Elements: 1
• Number of Bits per Element: 8
• Output Type: 3-State
• Current - Output High, Low: 24mA, 24mA
• Voltage - Supply: 1.65V ~ 3.6V
• Operating Temperature: -40°C ~ 85°C (TA)
• Mounting Type: Surface Mount
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Substitute parts are categorized into three groups:

Direct Manufacturer Equivalents maintain identical electrical specifications and package type (20-TSSOP), differing only in manufacturer and product status (Active).

Similar Parts maintain all electrical specifications but differ in package variant (20-TVSOP vs. 20-TSSOP) or series designation (74ALVCH vs. 74ALVC), requiring PCB layout verification.

Parametric Equivalents match all electrical and thermal specifications with identical packaging but differ in supply format (Tube vs. Tape & Reel).

Parameter Comparison

Engineering Selection Recommendations

For new designs and production transitions from the obsolete 74ALVC245MTC, the following selection criteria apply:

Direct Replacement Priority: SN74ALVC245PWR (Texas Instruments) and 74ALVC245PW,118 (Nexperia USA Inc.) are direct electrical and package equivalents with Active product status and ROHS3 compliance. These parts require no PCB layout modifications and provide the highest compatibility assurance.

Alternative with Series Variation: SN74ALVCH245PWR and SN74ALVCH245PW maintain identical electrical specifications and 20-TSSOP packaging but operate under the 74ALVCH series designation. These are functionally compatible alternatives with Active status and ROHS3 compliance.

Package Variant Consideration: SN74ALVC245DGVR and SN74ALVCH245DGVR employ 20-TFSOP packaging instead of 20-TSSOP. These parts maintain all electrical specifications but require PCB footprint verification before implementation.

Supply Format Variants: SN74ALVC245PW and SN74ALVCH245PW are supplied in Tube format rather than Tape & Reel, suitable for lower-volume applications or manual assembly processes.

All substitute parts maintain REACH Unaffected status and MSL 1 (Unlimited) moisture sensitivity classification, consistent with the original component.

Frequently Asked Questions (FAQ)

Q: Can SN74ALVC245PWR be used as a direct replacement for 74ALVC245MTC?

A: Yes. SN74ALVC245PWR matches all electrical parameters (1.65V ~ 3.6V supply, 24mA output current, -40°C ~ 85°C operating range), logic function (non-inverting transceiver, 8-bit, 3-state output), and package type (20-TSSOP). The primary difference is product status (Active vs. Obsolete) and manufacturer (Texas Instruments vs. onsemi).

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

A: Both series maintain identical electrical specifications for this transceiver function. The 74ALVCH designation represents a variant series from the same manufacturer. All electrical parameters, including supply voltage, output current, and operating temperature, remain unchanged. Series selection does not affect functional compatibility.

Q: Why do some substitute parts use 20-TFSOP packaging instead of 20-TSSOP?

A: SN74ALVC245DGVR and SN74ALVCH245DGVR employ 20-TFSOP (Thin Flat Small Outline Package) instead of 20-TSSOP (Thin Shrink Small Outline Package). While both are 20-pin surface-mount packages with identical electrical specifications, the physical footprint differs. PCB layout verification is required before substitution.

Q: Are all substitute parts RoHS compliant?

A: All substitute parts listed are ROHS3 Compliant. The original 74ALVC245MTC carries REACH Unaffected status. All substitute parts maintain REACH Unaffected classification and MSL 1 (Unlimited) moisture sensitivity level.

Q: What is the difference between Tape & Reel and Tube packaging?

A: Tape & Reel packaging is used for automated assembly processes and high-volume production. Tube packaging is used for manual assembly or lower-volume applications. Electrical specifications and component functionality remain identical; packaging format affects only handling and assembly methodology.

Q: Which substitute part offers the highest inventory availability?

A: SN74ALVC245PWR (Texas Instruments) provides the highest inventory availability at 8652 pieces. This part is a direct electrical and package equivalent with Active product status.
