CD74HC165M Equivalent & Substitute Parts

Part Overview

The CD74HC165M is an 8-bit parallel-load shift register manufactured by Texas Instruments, designed for serial data conversion applications in logic circuits. This device accepts parallel data input and converts it to serial output format, or accepts serial input and provides parallel output. The CD74HC165M operates across a 2V to 6V supply voltage range with an operating temperature range of -55°C to 125°C.

The CD74HC165M is currently discontinued at DiGi Electronics. Equivalent and substitute parts are available from multiple manufacturers including Texas Instruments, onsemi, and Nexperia USA Inc., offering continued design support and component availability for new and existing applications.

Substitute Part Grouping Explanation

Substitution of the CD74HC165M is determined by strict equivalence across the following parameters:

• Logic Type: Shift Register
• Number of Bits per Element: 8 bits
• Function: Parallel or Serial to Serial conversion
• Output Type: Complementary
• Voltage - Supply: 2V ~ 6V
• Package / Case: 16-SOIC (0.154", 3.90mm Width)
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

All substitute parts listed maintain identical electrical specifications and mechanical compatibility. Variations in operating temperature range and product status are noted but do not prevent functional substitution when application requirements are met.

Parameter Comparison

Engineering Selection Recommendations

For applications requiring the CD74HC165M, the following parts provide direct functional substitution:

CD74HC165M96 (Texas Instruments) is the primary active equivalent, maintaining identical electrical and thermal specifications with improved packaging availability in Cut Tape and Digi-Reel formats.

MC74HC165ADR2G (onsemi) and MC74HC165ADG (onsemi) are parametric equivalents with full electrical compatibility and active product status. MC74HC165ADR2G offers Cut Tape packaging, while MC74HC165ADG matches the original Tube packaging format.

74HC165D,653 (Nexperia USA Inc.) is an active manufacturer-recommended substitute with identical functional specifications. Operating temperature minimum is -40°C versus -55°C for the original part; this substitution is valid for applications not requiring extended low-temperature operation below -40°C.

74HC165D-Q100,118 (Nexperia USA Inc.) is an automotive-qualified variant (AEC-Q100) suitable for automotive and high-reliability applications. Operating temperature minimum is -40°C.

NLV74HC165ADR2G (onsemi) is listed as obsolete and should not be selected for new designs despite technical compatibility.

Frequently Asked Questions (FAQ)

Q: Can I substitute CD74HC165M with CD74HC165M96? A: Yes. CD74HC165M96 is the active equivalent from Texas Instruments with identical electrical specifications, thermal range (-55°C to 125°C), and 16-SOIC package. The primary difference is packaging format (Cut Tape & Digi-Reel versus Tube).

Q: What is the difference between the Nexperia parts 74HC165D,653 and 74HC165D-Q100,118? A: Both are from Nexperia USA Inc. with identical electrical function. 74HC165D-Q100,118 includes automotive qualification (AEC-Q100) and Tape & Reel packaging. 74HC165D,653 uses Cut Tape & Digi-Reel packaging. Both have -40°C minimum operating temperature.

Q: Are onsemi MC74HC165ADR2G and MC74HC165ADG interchangeable? A: Yes, electrically and functionally. Both are onsemi 74HC165 variants with -55°C to 125°C operating range and 2V to 6V supply. MC74HC165ADR2G uses Cut Tape & Digi-Reel packaging; MC74HC165ADG uses Tube packaging.

Q: Does operating temperature range affect substitution compatibility? A: Operating temperature range affects application suitability, not functional compatibility. Parts with -40°C minimum (Nexperia variants) are suitable for applications not requiring operation below -40°C. Parts with -55°C minimum (Texas Instruments and onsemi variants) support extended low-temperature operation.

Q: Can I use NLV74HC165ADR2G as a substitute? A: NLV74HC165ADR2G is technically compatible but is listed as obsolete. Active alternatives with identical specifications are available and should be prioritized for new designs.

Q: What packaging formats are available for CD74HC165M substitutes? A: Tube, Cut Tape (CT) & Digi-Reel®, and Tape & Reel (TR) formats are available across the substitute parts. Selection depends on procurement and assembly requirements.
