74HCT164N,652 Equivalent & Substitute Parts

Part Overview

The 74HCT164N,652 is an 8-bit serial-to-parallel shift register manufactured by NXP USA Inc., housed in a 14-DIP through-hole package. This logic component operates across a 4.5V to 5.5V supply voltage range with an operating temperature span of -40°C to 125°C. The part is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support, maintenance, and new design implementations where legacy compatibility is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 74HCT164N,652 is determined by strict equivalence across the following critical parameters: logic type (shift register), bit configuration (8-bit, single element), function (serial-to-parallel conversion), output type (push-pull), supply voltage range (4.5V ~ 5.5V), package form factor (14-DIP), and mounting method (through-hole). All identified substitutes maintain these core electrical and mechanical specifications. Substitutes are grouped by product status and manufacturer series designation, reflecting their availability and operational classification.

Parameter Comparison

Engineering Selection Recommendations

The 74HCT164N,652 is obsolete; active substitutes are available from multiple manufacturers. CD74HCT164E (Texas Instruments) and 74HCT164D14 (Diodes Incorporated) are direct series equivalents within the 74HCT logic family, both maintaining identical electrical specifications and package form factors. The 74AHCT164D14 (Diodes Incorporated) represents a parametric equivalent using the 74AHCT series, which provides extended lower temperature operation (-55°C minimum for the TI variant versus -40°C for the original and Diodes HCT variant). All substitutes are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. Selection should prioritize active-status parts with established supply chain availability.

Frequently Asked Questions (FAQ)

Q: Can the CD74HCT164E directly replace the 74HCT164N,652? A: Yes. Both parts share identical electrical specifications (4.5V ~ 5.5V supply, -40°C to 125°C operating range, 8-bit serial-to-parallel shift register function) and the same 14-DIP package form factor. The CD74HCT164E is manufactured by Texas Instruments and maintains active product status.

Q: What is the difference between 74HCT164D14 and 74AHCT164D14? A: Both are manufactured by Diodes Incorporated in 14-DIP packages with identical supply voltage and operating temperature ranges matching the original part. The 74AHCT164D14 uses the 74AHCT series designation. Both are functionally equivalent for the specified parameters.

Q: Are all substitutes available in the same package? A: Yes. All identified substitutes are housed in 14-DIP (0.300", 7.62mm) through-hole packages, ensuring direct mechanical compatibility with existing PCB layouts and socket configurations.

Q: Do the substitutes meet current compliance standards? A: Yes. All substitute parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component procurement.

Q: Why is the original 74HCT164N,652 classified as obsolete? A: The part is no longer in active production by NXP USA Inc. Active equivalents from Texas Instruments and Diodes Incorporated provide continued access to 8-bit serial-to-parallel shift register functionality in the same package configuration.
