SN74F245DWR Equivalent & Substitute Parts

Part Overview

The SN74F245DWR is a non-inverting transceiver logic integrated circuit manufactured by Texas Instruments. This 20-SOIC surface mount device functions as a single-element, 8-bit transceiver with 3-state output capability, operating within the 4.5V to 5.5V supply voltage range. The device maintains active product status and is RoHS3 compliant. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to inventory constraints, supply chain considerations, or design flexibility needs.

Key Parameters

Substitute Part Grouping Explanation

The SN74BCT245DWR qualifies as a parametric equivalent to the SN74F245DWR based on the following criteria:

Electrical Equivalence Parameters:

• Logic Type: Transceiver, Non-Inverting (identical)
• Number of Elements: 1 (identical)
• Number of Bits per Element: 8 (identical)
• Output Type: 3-State (identical)
• Current - Output High, Low: 3mA, 24mA; 15mA, 64mA (identical)
• Voltage - Supply: 4.5V ~ 5.5V (identical)
• Operating Temperature: 0°C ~ 70°C (TA) (identical)

Mechanical Equivalence Parameters:

• Package / Case: 20-SOIC (0.295", 7.50mm Width) (identical)
• Mounting Type: Surface Mount (identical)
• Supplier Device Package: 20-SOIC (identical)

Compliance Equivalence:

• RoHS Status: ROHS3 Compliant (identical)
• Moisture Sensitivity Level (MSL): 1 (Unlimited) (identical)
• REACH Status: REACH Unaffected (identical)
• Product Status: Active (identical)

The primary distinction between these parts lies in the logic series designation: SN74F245DWR operates within the 74F series, while SN74BCT245DWR operates within the 74BCT series. Both series maintain identical electrical performance specifications and mechanical compatibility within the specified parameters.
