GTLP8T306MTC Equivalent & Substitute Parts

Part Overview

The GTLP8T306MTC is a non-inverting transceiver IC manufactured by onsemi, designed for 8-bit signal translation with 3-state output capability. Operating within a supply voltage range of 3.15V to 3.45V, this component is housed in a 24-TSSOP surface mount package. The part is currently classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations.

Substitute Part Grouping Explanation

Substitution for the GTLP8T306MTC is determined by the following critical parameters:

Package Compatibility: Both substitute parts maintain the 24-TSSOP surface mount package with identical physical dimensions (0.173", 4.40mm Width)
Bit Configuration: All parts provide 8-bit per element configuration with single circuit architecture
Output Characteristics: Non-inverted tri-state output functionality is preserved across all alternatives
Operating Temperature Range: All parts operate within -40°C to 85°C (TA), matching the original specification
Voltage Supply Range: The substitute parts operate at GTLP voltage levels compatible with the original 3.15V ~ 3.45V specification
Electrical Performance: Output current specifications (24mA high/low) are maintained across all alternatives
Compliance Standards: All parts share identical REACH, ECCN, and HTSUS classifications

The SN74GTLPH306PW and SN74GTLPH306PWR are functionally equivalent mixed-signal translators from Texas Instruments that fulfill all electrical and mechanical requirements for direct substitution.

Engineering Selection Recommendations

Both SN74GTLPH306PW and SN74GTLPH306PWR from Texas Instruments are direct substitutes for the obsolete GTLP8T306MTC. Selection between the two Texas Instruments alternatives depends on procurement and assembly requirements:

SN74GTLPH306PW is supplied in tube packaging, suitable for lower-volume applications or manual assembly processes.

SN74GTLPH306PWR is supplied in tape and reel format, optimized for high-volume automated assembly operations. This variant offers greater inventory availability (2000 pcs vs. 783 pcs) and is the preferred choice for production environments.

Both alternatives maintain full compliance with ROHS3 standards and share identical electrical specifications, operating temperature ranges, and package dimensions. The transition from the obsolete onsemi part to either Texas Instruments equivalent requires no circuit redesign or board layout modifications.

Frequently Asked Questions (FAQ)

Q: Can SN74GTLPH306PW and SN74GTLPH306PWR be used interchangeably?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format: tube versus tape and reel. Selection should be based on assembly process requirements and procurement volume.

Q: Are there any pin-to-pin compatibility concerns?

A: No. All three parts use the 24-TSSOP package with identical pinout and physical dimensions (0.173", 4.40mm Width). Direct socket substitution is possible without board modifications.

Q: What is the difference between the onsemi GTLP8T306MTC and the Texas Instruments SN74GTLPH306 variants?

A: The onsemi part is classified as a non-inverting transceiver, while the Texas Instruments parts are classified as mixed-signal bidirectional translators. Both provide identical 8-bit, 3-state output functionality with non-inverted logic. The functional behavior and electrical performance are equivalent.

Q: Do the substitute parts meet the same compliance requirements?

A: Yes. All three parts share identical REACH, ECCN (EAR99), and HTSUS (8542.39.0001) classifications. The Texas Instruments alternatives are ROHS3 compliant, providing enhanced environmental compliance compared to the obsolete onsemi part.

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

A: All three parts operate across -40°C to 85°C (TA), ensuring compatibility across industrial and commercial temperature specifications.

Q: Are there any supply voltage differences?

A: The GTLP8T306MTC operates at 3.15V ~ 3.45V. The Texas Instruments SN74GTLPH306 variants are GTLP-compatible devices designed to operate at equivalent voltage levels, ensuring direct functional substitution.
