CD4504BME4 Equivalent & Substitute Parts

Part Overview

The CD4504BME4 is a voltage level translator IC manufactured by Texas Instruments, designed for unidirectional signal translation across different voltage domains. This 16-SOIC surface mount device features 1 circuit with 6 channels per circuit, supporting voltage translation between 5V to 15V supply rails with non-inverted output configuration.

The CD4504BME4 is currently discontinued at DiGi Electronics. Equivalent and substitute parts are available from active product lines, making component sourcing necessary for new designs and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CD4504BME4 is determined by the following critical parameters:

• Translator Type: Voltage Level
• Channel Type: Unidirectional
• Number of Circuits: 1
• Channels per Circuit: 6
• Output Type: Non-Inverted
• Package / Case: 16-SOIC (0.154", 3.90mm Width)
• Operating Temperature Range: -55°C ~ 125°C (TA)
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Substitute parts must maintain identical functional architecture, pinout compatibility, and environmental specifications. Voltage supply range variations are permissible when the substitute part's voltage range encompasses or exceeds the original specification.

Engineering Selection Recommendations

Primary Recommendation: CD4504BM

The CD4504BM is the manufacturer-recommended substitute from Texas Instruments. It maintains identical electrical specifications, voltage supply ranges (5V to 15V), and operating temperature performance as the CD4504BME4. The part is currently in active production status with 3200 units in stock. Packaging is supplied in Tube format. This selection ensures design continuity with the original component manufacturer.

Secondary Recommendation: MC14504BDR2G

The MC14504BDR2G from onsemi is a direct functional equivalent with expanded voltage supply capability (3V to 18V), providing greater design flexibility for mixed-voltage applications. This part is in active production status with substantial inventory availability (64650 units). Packaging is supplied in Tape & Reel format. The extended voltage range encompasses the original CD4504BME4 specification.

Alternative: NLV14504BDG

The NLV14504BDG from onsemi provides automotive-grade qualification (AEC-Q100) with identical functional parameters and expanded voltage range (3V to 18V). This part is currently obsolete but remains available in limited inventory (1040 units). Selection of this part is appropriate only for applications requiring automotive-grade certification and where existing stock is accessible.

Parametric Equivalent: CD4504BMG4

The CD4504BMG4 is a parametric equivalent from Texas Instruments with identical electrical specifications to the CD4504BME4. This part is discontinued at DiGi Electronics with 1075 units in stock. It serves as a direct replacement when CD4504BM availability is constrained.

Frequently Asked Questions (FAQ)

Q: Can MC14504BDR2G replace CD4504BME4 in designs operating at 5V to 15V?

A: Yes. The MC14504BDR2G voltage supply range (3V to 18V) encompasses the CD4504BME4 specification (5V to 15V). All other functional parameters—translator type, channel configuration, output type, operating temperature, and package—are identical. The part is pin-compatible and functionally equivalent.

Q: What is the difference between CD4504BM and CD4504BME4?

A: Both parts are manufactured by Texas Instruments with identical electrical specifications and functional architecture. The primary difference is product status: CD4504BME4 is discontinued at DiGi Electronics, while CD4504BM is in active production. The CD4504BM is the recommended replacement for new designs and production continuity.

Q: Is NLV14504BDG suitable for non-automotive applications?

A: Yes. The NLV14504BDG meets all functional requirements for standard industrial and commercial applications. The automotive-grade qualification (AEC-Q100) represents an additional certification level but does not restrict use in non-automotive designs. However, this part is currently obsolete; CD4504BM or MC14504BDR2G are preferred for new designs.

Q: Are all substitute parts available in 16-SOIC packaging?

A: Yes. All substitute parts listed are available in 16-SOIC (0.154", 3.90mm Width) surface mount packaging, ensuring PCB layout and assembly compatibility with the original CD4504BME4 design.

Q: What is the significance of the expanded voltage range in MC14504BDR2G?

A: The MC14504BDR2G supports 3V to 18V supply rails compared to the CD4504BME4 specification of 5V to 15V. This expanded range provides design flexibility for applications requiring lower supply voltages (3V to 5V) or higher supply voltages (15V to 18V) without component substitution. For designs operating strictly within 5V to 15V, both parts are functionally equivalent.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed—CD4504BM, MC14504BDR2G, NLV14504BDG, and CD4504BMG4—are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited), matching the environmental compliance profile of the CD4504BME4.
