SN7407DRE4 Equivalent & Substitute Parts

Part Overview

The SN7407DRE4 is a Buffer, Non-Inverting logic IC manufactured by Texas Instruments, featuring 6 elements with 1 bit per element and open collector output configuration. The device operates within a 4.75V to 5.25V supply voltage range and is housed in a 14-SOIC package. This part is currently discontinued at DiGi Electronics, making equivalent substitute parts necessary for ongoing design requirements and production continuity.

Substitute Part Grouping Explanation

Substitution for the SN7407DRE4 is determined by strict equivalence across the following critical parameters:

Logic Type: Buffer, Non-Inverting
Number of Elements: 6
Number of Bits per Element: 1
Output Type: Open Collector
Current - Output Low: 40mA
Voltage - Supply: 4.75V ~ 5.25V
Operating Temperature: 0°C ~ 70°C (TA)
Package / Case: 14-SOIC (0.154", 3.90mm Width)
Mounting Type: Surface Mount

All substitute parts listed maintain identical electrical and mechanical specifications across these parameters. Variations exist only in product series designation (7400 vs. 74LS), packaging format (Cut Tape, Digi-Reel, or Tape & Reel), and product availability status.

Engineering Selection Recommendations

For applications requiring the SN7407DRE4, the following selection criteria apply:

Primary Recommendation: SN7407DR is the direct functional equivalent with identical electrical and mechanical specifications. This part is currently active and maintains the highest inventory availability (105,300 units), ensuring supply continuity. Both parts belong to the 7400 series and are ROHS3 compliant with unlimited moisture sensitivity rating.

Secondary Recommendation: SN74LS07DR provides equivalent functionality within the 74LS series variant. This part is active with substantial inventory (17,800 units) and maintains all critical electrical parameters. The 74LS designation indicates low-power Schottky logic technology, functionally compatible with the original specification.

Alternative Options: SN7417DR (7400 series, 2,400 units available) and SN74LS07DRE4 (74LS series, 11,904 units available) are functionally equivalent alternatives. SN74LS07DRE4 shares the DRE4 packaging designation with the original part but is currently discontinued at DiGi Electronics.

All substitute parts maintain ROHS3 compliance, REACH unaffected status, and identical package specifications (14-SOIC, 0.154" width, 3.90mm).

Frequently Asked Questions (FAQ)

Q: Can SN7407DR be used as a direct replacement for SN7407DRE4?

A: Yes. Both parts are identical in logic type, element count, output configuration, supply voltage range, operating temperature, and 14-SOIC package specification. The primary difference is packaging format (Cut Tape & Digi-Reel vs. Tape & Reel) and product status (Active vs. Discontinued).

Q: What is the difference between the 7400 and 74LS series variants?

A: Both series maintain identical electrical specifications for this buffer function, including output current, supply voltage, and operating temperature. The 74LS designation indicates low-power Schottky logic technology. All listed parts are functionally equivalent for the specified application parameters.

Q: Are there any compatibility concerns when substituting between these parts?

A: No compatibility concerns exist. All substitute parts share identical logic type, element configuration, output type, current ratings, voltage specifications, operating temperature range, and 14-SOIC package dimensions. Pin configuration and functional behavior remain constant across all listed equivalents.

Q: Why is the SN7407DRE4 discontinued while SN7407DR remains active?

A: Product discontinuation decisions are based on supplier inventory management and market demand. SN7407DR, with significantly higher inventory availability, remains the active production variant. Both parts are functionally identical.

Q: Which substitute part should be selected for new designs?

A: SN7407DR is recommended for new designs due to active product status and highest inventory availability. SN74LS07DR is an acceptable alternative within the 74LS series. Both parts meet all electrical and mechanical requirements specified for the original SN7407DRE4.
