Key Parameters

Substitute Part Grouping Explanation

Substitution of the 74HC253DB,112 is determined by strict alignment of electrical and mechanical parameters within the 74HC253 logic family. Valid substitutes must maintain identical circuit configuration (2 x 4:1 multiplexer), package type (16-SSOP), mounting method (surface mount), voltage supply range (2V to 6V), and output current specifications (7.8mA). The operating temperature range and product status are secondary considerations that do not prevent substitution when primary electrical and mechanical parameters are matched. All identified substitutes comply with ROHS3 and maintain MSL 1 classification.

Parameter Comparison

Engineering Selection Recommendations

The SN74HC253DBR manufactured by Texas Instruments is a direct electrical and mechanical equivalent to the 74HC253DB,112. Both components share identical circuit configuration, package specifications, voltage supply parameters, and output current ratings. The Texas Instruments part carries active product status and ROHS3 compliance, supporting long-term availability. The operating temperature range difference (-40°C to 85°C versus -40°C to 125°C) does not prevent substitution in applications operating within the Texas Instruments specification window.

The 74HC253DB,112 from NXP Semiconductors is a parametric equivalent offering identical electrical and mechanical specifications with extended operating temperature range (-40°C to 125°C) matching the original Nexperia part. This variant maintains active product status and ROHS3 compliance. The MSL rating is listed as vendor undefined, requiring verification against specific application requirements if moisture sensitivity is a critical design parameter.

Frequently Asked Questions (FAQ)

Q: Can the SN74HC253DBR replace the obsolete 74HC253DB,112 in existing designs?

A: Yes. The SN74HC253DBR meets all primary electrical and mechanical substitution criteria: identical 2 x 4:1 circuit configuration, 16-SSOP package, 2V to 6V supply voltage, and 7.8mA output current specifications. Both components are surface mount devices with ROHS3 compliance. Designs operating within the SN74HC253DBR temperature range (-40°C to 85°C) require no circuit modifications.

Q: What is the difference between the Nexperia and NXP versions of 74HC253DB,112?

A: Both versions share identical electrical specifications and 16-SSOP packaging. The primary difference is manufacturer designation and product status. The NXP Semiconductors version maintains active status with extended temperature range support (-40°C to 125°C). The Nexperia version is classified as obsolete. Both comply with ROHS3 standards.

Q: Are there packaging differences between these substitutes?

A: All three parts use identical 16-SSOP surface mount packaging (0.209" width, 5.30mm). The SN74HC253DBR is supplied in Tape & Reel format, while the Nexperia part is supplied in Bulk. The NXP version packaging format is not specified. Package format does not affect electrical compatibility or PCB layout requirements.

Q: What compliance certifications apply to these parts?

A: All identified substitutes maintain ROHS3 compliance and REACH unaffected status. MSL ratings are 1 (Unlimited) for Nexperia and Texas Instruments parts. The NXP version lists MSL as vendor undefined. All parts carry EAR99 ECCN classification and HTSUS code 8542.39.0001.
