CD74HC237M96 Equivalent & Substitute Parts
Part Overview
The CD74HC237M96 is a decoder/demultiplexer logic integrated circuit manufactured by Texas Instruments in the 74HC series. This device implements a 1 x 3:8 decoder/demultiplexer function in a 16-SOIC surface mount package. The part is currently active in production with 1630 units in stock. Substitute parts are necessary when the primary part number becomes unavailable, when alternative packaging formats are required for manufacturing processes, or when sourcing from multiple manufacturers is needed for supply chain resilience.

Substitute Part Grouping Explanation
Substitution of the CD74HC237M96 is determined by the following critical parameters that must remain constant across all equivalent parts:
- Decoder/Demultiplexer function type with 1 x 3:8 circuit configuration
- 16-SOIC surface mount package with 0.154" width (3.90mm)
- Voltage supply range of 2V ~ 6V
- Output current specifications of 5.2mA (high and low)
- Operating temperature range of -55°C ~ 125°C or compatible subset
- RoHS3 compliance and MSL 1 rating
Substitute parts are grouped into three categories: parametric equivalents from Texas Instruments with alternative packaging formats, parametric equivalents from other manufacturers (onsemi, STMicroelectronics, NXP Semiconductors), and manufacturer-recommended alternatives. All listed substitutes maintain identical electrical specifications and package dimensions, differing only in packaging format (Tape & Reel, Cut Tape, or Bulk) and manufacturer source.

Engineering Selection Recommendations
For active production designs, select from parts with Active product status: CD74HC237M96, CD74HC138M96, CD74HC238M96, 74HC237D,652, 74HC237D,653, MC74HC138ADR2G, or MC74HC238ADR2G. All active parts maintain ROHS3 compliance and MSL 1 rating.
When packaging format flexibility is required, CD74HC138M96 and CD74HC238M96 offer Cut Tape & Digi-Reel packaging as alternatives to the standard Tape & Reel format of CD74HC237M96. For designs requiring bulk quantities, 74HC237D,652 from NXP Semiconductors is available in bulk packaging.
Parts with Discontinued or Obsolete status (CD74HC138MT, CD74HC238MT, M74HC238RM13TR, NLV74HC138ADR2G) should be used only when existing inventory is available and no active alternatives are suitable. The NXP and Nexperia parts (74HC237D,652 and 74HC237D,653) operate at a reduced minimum temperature of -40°C compared to the -55°C minimum of the Texas Instruments and onsemi alternatives; this difference is acceptable for applications not requiring the extended low-temperature range.
Frequently Asked Questions (FAQ)
Q: Can CD74HC138M96 be used as a direct substitute for CD74HC237M96?
A: Yes. Both parts share identical electrical specifications (1 x 3:8 decoder/demultiplexer, 2V ~ 6V supply, 5.2mA output current, -55°C ~ 125°C operating range) and the same 16-SOIC package. The difference is packaging format: CD74HC138M96 uses Cut Tape & Digi-Reel while CD74HC237M96 uses Tape & Reel. Electrical performance and PCB footprint are identical.
Q: What is the difference between the Texas Instruments 74HC237 and 74HC238 variants?
A: From the provided specifications, both the 74HC237 and 74HC238 base products implement the same 1 x 3:8 decoder/demultiplexer function with identical electrical parameters. The substitution list indicates they are functionally equivalent for this application.
Q: Are the NXP 74HC237D,652 and 74HC237D,653 parts fully compatible?
A: Both NXP parts are compatible with the CD74HC237M96 in terms of electrical function and package. The difference is packaging format: 74HC237D,652 is supplied in Bulk, while 74HC237D,653 is supplied in Tape & Reel. Both operate at -40°C ~ 125°C, which is a narrower temperature range than the -55°C ~ 125°C of the Texas Instruments part.
Q: Can I use onsemi MC74HC138ADR2G or MC74HC238ADR2G in place of the CD74HC237M96?
A: Yes. Both onsemi parts are parametric equivalents with identical electrical specifications and 16-SOIC package. They are supplied in Cut Tape & Digi-Reel format and maintain the full -55°C ~ 125°C operating temperature range and ROHS3 compliance.
Q: Should I avoid parts marked as Obsolete or Discontinued?
A: Parts with Obsolete or Discontinued status should be used only when existing inventory is confirmed available. For new designs or ongoing production, select from parts with Active status to ensure long-term supply availability.
Q: Does the operating temperature range difference between -55°C and -40°C affect my design?
A: This depends on your application requirements. If your design operates only above -40°C, the NXP parts (74HC237D,652 and 74HC237D,653) are fully suitable. If your application requires operation down to -55°C, use Texas Instruments, onsemi, or STMicroelectronics alternatives.
