SN74LVC245APW-P Equivalent & Substitute Parts

Part Overview

The SN74LVC245APW-P is a non-inverting transceiver logic integrated circuit manufactured by Texas Instruments. This device functions as a 1-element, 8-bit per element transceiver with 3-state output capability, housed in a 20-TSSOP surface mount package. The part is classified as Active product status and is ROHS3 compliant. Substitute parts are identified when packaging format differs or when equivalent series variants are required for specific procurement or inventory conditions.

Substitute Part Grouping Explanation

Substitute parts for the SN74LVC245APW-P are identified based on strict electrical and mechanical parameter equivalence. The substitution logic is based on the following criteria:

Core Equivalence 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 ~ 125°C (TA)
• Package / Case: 20-TSSOP (0.173", 4.40mm Width)
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

The identified substitute parts maintain identical electrical specifications and mechanical compatibility. Differences exist only in packaging format (Tape & Reel versus individual packaging) and series designation (74LVC versus 74LVCH).

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain full electrical and mechanical compatibility with the SN74LVC245APW-P. Selection between the main part and substitutes is determined by procurement requirements and packaging format availability.

SN74LVC245APWT: This part is electrically identical to the SN74LVC245APW-P, differing only in packaging format (Tape & Reel). Both parts belong to the 74LVC series and carry Active product status with ROHS3 compliance. This substitute is suitable for high-volume production environments where tape and reel packaging is standard.

SN74LVCH245APWT: This part maintains all electrical specifications and mechanical dimensions of the SN74LVC245APW-P but belongs to the 74LVCH series variant. The part is supplied in Tape & Reel format and carries Active product status with ROHS3 compliance. This substitute is suitable when 74LVCH series components are specified or preferred in system design.

All three parts are manufactured by Texas Instruments, carry Active product status, and meet ROHS3 compliance requirements. Selection should be based on packaging format requirements and series designation specifications for the target application.

Frequently Asked Questions (FAQ)

Q: Can SN74LVC245APWT be used as a direct replacement for SN74LVC245APW-P?

A: Yes. Both parts are electrically and mechanically identical. The difference is packaging format: SN74LVC245APW-P is supplied individually, while SN74LVC245APWT is supplied in Tape & Reel format. Both are suitable for surface mount assembly on 20-TSSOP footprints.

Q: What is the difference between the 74LVC and 74LVCH series?

A: Both series maintain identical electrical specifications for this transceiver application, including supply voltage range (1.65V ~ 3.6V), output current (24mA), and operating temperature range (-40°C ~ 125°C). The series designation reflects internal design variants. Selection between series should follow system design specifications.

Q: Are all three parts ROHS3 compliant?

A: Yes. SN74LVC245APW-P, SN74LVC245APWT, and SN74LVCH245APWT are all ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited).

Q: What packaging format should I select for my application?

A: SN74LVC245APW-P is supplied in individual packaging. SN74LVC245APWT and SN74LVCH245APWT are supplied in Tape & Reel format. Tape & Reel packaging is standard for automated assembly processes. Individual packaging is suitable for prototype or low-volume applications.

Q: Do these parts have identical pin configurations?

A: Yes. All three parts use the 20-TSSOP package with identical pin assignments and mechanical dimensions (0.173" width, 4.40mm).

Q: What is the operating temperature range for these parts?

A: All three parts operate across -40°C to 125°C (TA), suitable for industrial and commercial temperature environments.
