SN74HC164PWT 8-Bit Shift Register Equivalent & Substitute Parts

Part Overview

The SN74HC164PWT is an 8-bit serial-in parallel-out shift register manufactured by Texas Instruments in a 14-TSSOP surface mount package. This logic component converts serial input data into parallel output format and operates across a 2V to 6V supply voltage range with an operating temperature range of -40°C to 125°C. The part is currently discontinued at DiGi Electronics, making equivalent and substitute parts necessary for ongoing design requirements and production needs.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the SN74HC164PWT is determined by strict equivalence across the following parameters: Logic Type (Shift Register), Function (Serial to Parallel), Number of Bits per Element (8), Number of Elements (1), Output Type (Push-Pull), Voltage Supply Range (2V ~ 6V), Package Type (14-TSSOP), and Mounting Type (Surface Mount). All substitute parts listed maintain these core electrical and mechanical specifications. Operating temperature range variations and product status differences are noted but do not prevent functional substitution when the application requirements fall within the overlapping temperature specifications.

Parameter Comparison

Engineering Selection Recommendations

For applications requiring direct replacement of the discontinued SN74HC164PWT, the SN74HC164PWR from Texas Instruments is the primary choice, offering identical electrical specifications and active product status with equivalent packaging options. The 74HC164PW,118 from Nexperia USA Inc. and 74HC164T14-13 from Diodes Incorporated provide active alternatives with matching temperature and voltage specifications. The MC74HC164ADTR2G from onsemi extends the lower operating temperature to -55°C, suitable for applications requiring enhanced cold-temperature performance. The 74HC164PW-Q100J variant from Nexperia includes AEC-Q100 automotive qualification for applications requiring automotive-grade components. The MM74HC164MTCX from Fairchild Semiconductor operates to a maximum of 85°C and should be selected only when the application temperature range does not exceed this limit. The NLV74HC164ADTR2G from onsemi is marked obsolete and should be avoided for new designs despite its extended temperature range.

Frequently Asked Questions (FAQ)

Q: Can I substitute SN74HC164PWT with SN74HC164PWR? A: Yes. Both parts are manufactured by Texas Instruments with identical electrical specifications (2V ~ 6V supply, -40°C ~ 125°C operating range, 8-bit serial-to-parallel shift register function). The primary difference is packaging format: SN74HC164PWT uses Tape & Reel while SN74HC164PWR uses Cut Tape & Digi-Reel. Both are 14-TSSOP surface mount packages with equivalent pinouts.

Q: What is the difference between the Nexperia 74HC164PW,118 and 74HC164PW-Q100J? A: Both are 8-bit shift registers from Nexperia with identical electrical specifications. The 74HC164PW-Q100J includes AEC-Q100 automotive qualification and is supplied in Tape & Reel packaging, while the 74HC164PW,118 is supplied in Cut Tape & Digi-Reel format. Select the Q100J variant for automotive applications.

Q: Why does MC74HC164ADTR2G have a lower operating temperature limit of -55°C? A: The MC74HC164ADTR2G from onsemi is specified for an extended lower temperature range (-55°C to 125°C) compared to the original SN74HC164PWT (-40°C to 125°C). This extended range does not affect substitution compatibility; it indicates the part is qualified for colder operating environments.

Q: Should I use MM74HC164MTCX as a substitute? A: The MM74HC164MTCX from Fairchild Semiconductor is functionally equivalent but has a reduced upper operating temperature limit of 85°C compared to 125°C for other alternatives. Use this part only if your application operates within the -40°C to 85°C range.

Q: Is NLV74HC164ADTR2G still available for new designs? A: No. The NLV74HC164ADTR2G is marked as obsolete and should not be selected for new designs. Choose from the active alternatives listed in the parameter comparison table.

Q: Are all substitute parts RoHS3 compliant? A: Most substitute parts are ROHS3 compliant. The MM74HC164MTCX from Fairchild Semiconductor does not specify RoHS status in the provided data. Verify RoHS compliance requirements with your procurement specifications before selection.

Q: Can I use these parts interchangeably in my PCB design? A: Yes, all listed substitute parts use the 14-TSSOP surface mount package with identical pinouts and electrical characteristics. PCB layout and footprints designed for SN74HC164PWT are compatible with all substitute parts listed.
