SN75452BDR Equivalent & Substitute Parts

Part Overview

The SN75452BDR is a peripheral driver logic integrated circuit manufactured by Texas Instruments, designed for open collector output applications in 5V logic systems. This device functions as a 2-element, 2-bit per element peripheral driver with a maximum output current of 300mA per channel, housed in an 8-SOIC surface mount package. The SN75452BDR maintains active product status with 16,300 units in current inventory and full ROHS3 compliance.

Substitute parts become necessary when the primary part number experiences supply constraints, inventory depletion, or when design flexibility permits selection from the SN754xx peripheral driver family. All substitute parts listed maintain identical electrical specifications and mechanical compatibility with the SN75452BDR.

Substitute Part Grouping Explanation

All substitute parts for the SN75452BDR are selected from the Texas Instruments SN754xx peripheral driver family based on strict parametric equivalence. Substitution eligibility is determined by the following criteria:

Logic Type: Peripheral Driver
Number of Elements: 2
Number of Bits per Element: 2
Output Type: Open Collector
Current - Output Low: 300mA
Voltage - Supply: 4.75V ~ 5.25V
Operating Temperature: 0°C ~ 70°C (TA)
Package / Case: 8-SOIC (0.154", 3.90mm Width)
Mounting Type: Surface Mount
RoHS Status: ROHS3 Compliant
Moisture Sensitivity Level: 1 (Unlimited)

All listed substitute parts meet these criteria without exception. Substitution is valid for any application where the SN75452BDR is specified, provided the design does not impose additional constraints beyond the parameters listed above.

Engineering Selection Recommendations

For new designs and production applications, SN75451BDR is the preferred substitute due to its active product status and highest inventory availability (35,200 units). This part maintains full ROHS3 compliance and identical electrical and mechanical specifications to the SN75452BDR.

SN75453BDR and SN75454BDR are secondary alternatives, both maintaining active product status with adequate inventory levels (18,396 and 2,648 units respectively). Both parts carry full ROHS3 compliance and meet all parametric requirements.

SN75451BDRG4 is not recommended for new designs due to its discontinued status at DiGi Electronics, despite current inventory availability of 2,102 units. This part should be reserved for legacy system maintenance only.

All substitute parts carry identical REACH unaffected status and EAR99 export classification as the primary part.

Frequently Asked Questions (FAQ)

Q: Can SN75451BDR replace SN75452BDR in existing designs?

A: Yes. Both parts are parametrically equivalent across all electrical and mechanical specifications, including logic type, element count, bit configuration, output type, current rating, supply voltage, operating temperature range, package type, and compliance certifications.

Q: Are there any differences in pin configuration between substitute parts?

A: No. All substitute parts use the 8-SOIC package with identical 0.154" (3.90mm) width. Pin assignments and functional equivalence are maintained across all listed parts.

Q: Why is SN75451BDRG4 marked as discontinued?

A: SN75451BDRG4 is discontinued at DiGi Electronics as a distribution channel, though limited inventory remains available. This status does not affect electrical or mechanical compatibility but indicates reduced long-term availability.

Q: What is the significance of the "G4" suffix in SN75451BDRG4?

A: The "G4" suffix represents a specific manufacturing date code or packaging variant. Functionally, SN75451BDRG4 is equivalent to SN75451BDR for all application purposes.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance with Moisture Sensitivity Level 1 (unlimited shelf life) and REACH unaffected status.

Q: Which substitute part offers the best inventory availability?

A: SN75451BDR provides the highest inventory level at 35,200 units, making it the most readily available substitute for the SN75452BDR.
