Key Parameters

Substitute Part Grouping Explanation

Substitution of the SN75154DG4 is determined by the following critical parameters:

• Protocol Compatibility: RS232 receiver functionality
• Receiver Configuration: 0/4 (zero drivers, four receivers)
• Receiver Hysteresis: 3.3 V threshold specification
• Supply Voltage Range: 4.5V ~ 5.5V operation
• Operating Temperature Range: 0°C ~ 70°C
• Package Type: 16-SOIC surface mount form factor
• Regulatory Compliance: ROHS3 Compliant, REACH Unaffected status

The SN75154D qualifies as a direct substitute based on matching all critical electrical and mechanical parameters within the allowed specification range.

Parameter Comparison

Engineering Selection Recommendations

The SN75154D is a direct functional equivalent to the SN75154DG4. Both components are manufactured by Texas Instruments and maintain identical electrical specifications for RS232 receiver operation. The SN75154D carries Last Time Buy status, indicating limited future availability. Both parts maintain ROHS3 compliance and REACH Unaffected regulatory status, suitable for applications requiring environmental compliance certification.

Selection between these parts should be based on current procurement availability and supply chain requirements, as the SN75154DG4 is discontinued and the SN75154D is in Last Time Buy status.

Frequently Asked Questions (FAQ)

Q: Can the SN75154D replace the SN75154DG4 in existing designs?

A: Yes. The SN75154D is electrically and mechanically equivalent to the SN75154DG4. Both components share identical receiver configuration (0/4), hysteresis specification (3.3 V), supply voltage range (4.5V ~ 5.5V), operating temperature range (0°C ~ 70°C), and 16-SOIC package form factor.

Q: What is the difference between SN75154DG4 and SN75154D?

A: The primary difference is product status and packaging. The SN75154DG4 is discontinued at DiGi Electronics, while the SN75154D is in Last Time Buy status. The SN75154D is supplied in Tube packaging. All electrical and mechanical specifications are identical.

Q: Are there any compliance differences between these parts?

A: No. Both the SN75154DG4 and SN75154D maintain ROHS3 compliance and REACH Unaffected status. Moisture Sensitivity Level (MSL) is 1 (Unlimited) for both parts.

Q: What does 0/4 receiver configuration mean?

A: The 0/4 designation indicates zero driver channels and four receiver channels. This component is designed for receiving RS232 serial data only, without transmission capability.

Q: Is the 16-SOIC package compatible with existing PCB layouts?

A: Yes. Both the SN75154DG4 and SN75154D use the identical 16-SOIC (0.154", 3.90mm Width) surface mount package. PCB footprints and reflow profiles remain unchanged.
