CD4094BPW Equivalent & Substitute Parts

Part Overview

The CD4094BPW is an 8-bit shift register with storage capability, manufactured by Texas Instruments in the 4000B CMOS logic series. This device functions as a serial-to-parallel converter with tri-state output, operating across a wide supply voltage range of 3V to 18V and temperature range of -55°C to 125°C. The part is discontinued at DiGi Electronics, making equivalent substitutes necessary for ongoing design requirements and production needs. All substitute parts maintain identical logic functionality, packaging footprint, and electrical performance within the specified operating parameters.

Substitute Part Grouping Explanation

Substitution eligibility for the CD4094BPW is determined by strict equivalence across the following critical parameters:

Logic Type: Shift Register (8-bit, 1 element)
Function: Serial to Parallel conversion
Output Type: Tri-State
Package: 16-TSSOP footprint compatibility
Supply Voltage Range: Minimum 3V to 18V support
Operating Temperature Range: Minimum -55°C to 125°C support
RoHS3 Compliance and MSL Level 1 rating

All identified substitute parts meet these core requirements. Variations in operating temperature range or supply voltage limits are noted where they represent narrower specifications than the original part.

Engineering Selection Recommendations

For direct replacement of the discontinued CD4094BPW in standard industrial applications, CD4094BPWR (Texas Instruments, active status) provides identical electrical and thermal specifications with the same 3V to 18V supply range and -55°C to 125°C operating window.

MC14094BDTR2G (onsemi) and NLV14094BDTR2G (onsemi) are functionally equivalent alternatives with full parameter compatibility. NLV14094BDTR2G includes AEC-Q100 automotive qualification, suitable for applications requiring automotive-grade components.

For applications with reduced temperature requirements (-40°C to 85°C), BU4094BCFV-E2 (Rohm Semiconductor) is a viable option, though it uses a 16-LSSOP package variant rather than standard 16-TSSOP.

HEF4094BTT-Q100J and HEF4094BTTJ (Nexperia) operate within a narrower supply voltage range (3V to 15V) and reduced low-temperature specification (-40°C minimum). These parts are suitable only for applications that do not require operation below -40°C or above 15V supply voltage. HEF4094BTT-Q100J carries AEC-Q100 automotive qualification.

All substitute parts maintain ROHS3 compliance and MSL Level 1 rating, ensuring compatibility with standard manufacturing and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can CD4094BPWR directly replace CD4094BPW? A: Yes. CD4094BPWR is the active production equivalent from the same manufacturer with identical electrical specifications, supply voltage range (3V to 18V), operating temperature range (-55°C to 125°C), and 16-TSSOP package footprint.

Q: What is the difference between CD4094BPWR and MC14094BDTR2G? A: Both parts are functionally equivalent with identical logic specifications and operating parameters. The primary difference is manufacturer (Texas Instruments versus onsemi) and packaging format (Cut Tape & Digi-Reel versus Tape & Reel). Electrical performance and pinout are identical.

Q: Why does BU4094BCFV-E2 have a different operating temperature range? A: BU4094BCFV-E2 is specified for -40°C to 85°C operation, which is narrower than the original CD4094BPW specification of -55°C to 125°C. This part is suitable only for applications that do not require operation outside this temperature window.

Q: What does AEC-Q100 qualification mean? A: AEC-Q100 is an automotive industry qualification standard. HEF4094BTT-Q100J and NLV14094BDTR2G carry this certification, indicating suitability for automotive applications requiring enhanced reliability and quality assurance.

Q: Are there package differences between substitute parts? A: Most substitutes use 16-TSSOP packaging. BU4094BCFV-E2 uses 16-LSSOP (16-SSOP-B), which has the same 0.173" width and 4.40mm pitch but is a variant package. Verify PCB footprint compatibility before selection.

Q: Can HEF4094BTTJ be used in applications requiring 18V supply? A: No. HEF4094BTTJ is specified for 3V to 15V supply voltage. Applications requiring operation at 18V must use CD4094BPWR, MC14094BDTR2G, or NLV14094BDTR2G.

Q: Which substitute offers the widest operating range? A: CD4094BPWR, MC14094BDTR2G, and NLV14094BDTR2G all support the full 3V to 18V supply range and -55°C to 125°C temperature range, matching the original CD4094BPW specifications.
