Substitute Part Grouping Explanation

Substitution eligibility for the SN74HC367PWT is determined by strict equivalence across the following critical parameters:

Logic Type: Buffer, Non-Inverting
Number of Elements: 2
Number of Bits per Element: 2, 4 (Hex)
Output Type: 3-State
Current - Output High, Low: 7.8mA, 7.8mA
Voltage - Supply: 2V ~ 6V
Package / Case: 16-TSSOP (0.173", 4.40mm Width)
Mounting Type: Surface Mount
Base Product Number: 74HC367

All identified substitute parts maintain these core electrical and mechanical specifications. Variations in operating temperature range and product status are noted but do not affect functional interchangeability within the specified supply voltage and output current parameters.

Engineering Selection Recommendations

SN74HC367PWR (Texas Instruments) is the primary parametric equivalent. This part maintains identical electrical specifications and operating temperature range to the main part while offering active product status, ensuring continued availability and manufacturing support.

74HC367PW,118 (Nexperia USA Inc.) provides extended operating temperature range (-40°C to 125°C) compared to the main part (-40°C to 85°C). This part is suitable for applications requiring broader temperature performance while maintaining all core electrical parameters. Active product status ensures supply continuity.

MC74HC367ADTR2G (onsemi) offers the widest operating temperature range (-55°C to 125°C) but carries obsolete product status. This part is electrically equivalent but may present supply chain constraints. Selection should be based on specific temperature requirements and availability verification.

All substitute parts maintain ROHS3 compliance and MSL 1 rating, ensuring compatibility with standard manufacturing and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can SN74HC367PWR be used as a direct replacement for SN74HC367PWT?

A: Yes. Both parts share identical logic type, element configuration, output type, current ratings, supply voltage range, and 16-TSSOP package. Operating temperature ranges are equivalent (-40°C to 85°C). The primary difference is product status; SN74HC367PWR is active while SN74HC367PWT is discontinued.

Q: What is the difference between the three substitute parts?

A: All three maintain core electrical equivalence. SN74HC367PWR (Texas Instruments) and 74HC367PW,118 (Nexperia) are active products. The Nexperia part extends operating temperature to 125°C. MC74HC367ADTR2G (onsemi) offers the widest temperature range (-55°C to 125°C) but is obsolete.

Q: Are there package differences between these parts?

A: All parts use 16-TSSOP surface mount packaging with identical dimensions (0.173", 4.40mm width). No package conversion or board redesign is required for substitution.

Q: Which substitute should I select for new designs?

A: SN74HC367PWR or 74HC367PW,118 are recommended for new designs due to active product status. Selection between these two depends on operating temperature requirements. If your application operates within -40°C to 85°C, either part is suitable. For extended temperature operation to 125°C, select 74HC367PW,118.

Q: Are all parts RoHS compliant?

A: Yes. All parts listed maintain ROHS3 compliance and MSL 1 rating, meeting standard environmental and manufacturing requirements.

Q: Can MC74HC367ADTR2G be used despite obsolete status?

A: MC74HC367ADTR2G is electrically equivalent and functionally interchangeable. However, obsolete status indicates discontinued manufacturing. Use only if existing inventory is available and supply chain verification confirms availability.
