CD40175BPW Equivalent & Substitute Parts

Part Overview

The CD40175BPW is a D-type flip-flop logic integrated circuit manufactured by Texas Instruments, part of the 4000B CMOS logic series. This component functions as a master reset flip-flop with 1 element, 4-bit configuration, and complementary output type. The CD40175BPW is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. Substitute parts must maintain functional equivalence across electrical characteristics, package compatibility, and operational parameters to ensure direct replacement capability.

Engineering Selection Recommendations

CD40175BPWR (Texas Instruments): This part is the direct Texas Instruments equivalent with active product status. It maintains identical electrical specifications, package geometry, and compliance certifications as the obsolete CD40175BPW. The CD40175BPWR is supplied in Tape & Reel packaging format and represents the primary substitute for direct replacement in new production and redesign scenarios. ROHS3 compliance and MSL Level 1 classification match the original specification.

HEF40175BTT,118 (NXP USA Inc.): This NXP alternative provides functional equivalence with enhanced performance characteristics. The HEF40175BTT,118 offers superior clock frequency (45 MHz versus 14 MHz) and reduced propagation delay (45ns versus 120ns), enabling operation in higher-speed applications. Output current is reduced to 3.4mA per output. The maximum supply voltage is limited to 15V compared to 18V for the Texas Instruments variants. Operating temperature range begins at -40°C rather than -55°C. This part is supplied in Bulk packaging and is suitable for applications where the enhanced speed performance and lower output current are compatible with system requirements.

Frequently Asked Questions (FAQ)

Q: Can CD40175BPWR directly replace CD40175BPW in existing designs? A: Yes. The CD40175BPWR maintains identical electrical specifications, package footprint (16-TSSOP), mounting type (surface mount), and compliance certifications. Direct PCB-level substitution is supported without design modification.

Q: What are the key differences between CD40175BPWR and HEF40175BTT,118? A: Both parts share identical logic function, package geometry, and core electrical characteristics. The HEF40175BTT,118 provides higher clock frequency (45 MHz versus 14 MHz), faster propagation delay (45ns versus 120ns), and lower output current (3.4mA versus 6.8mA). The maximum supply voltage for HEF40175BTT,118 is 15V, and the minimum operating temperature is -40°C instead of -55°C.

Q: Is the HEF40175BTT,118 suitable for applications requiring -55°C operation? A: No. The HEF40175BTT,118 operating temperature range is -40°C to 125°C. Applications requiring -55°C minimum temperature must use CD40175BPWR or CD40175BPW.

Q: Are there packaging format differences between substitute parts? A: Yes. CD40175BPWR is supplied in Tape & Reel format, while HEF40175BTT,118 is supplied in Bulk format. Packaging selection depends on production volume and assembly process requirements.

Q: Do all substitute parts meet RoHS3 compliance? A: CD40175BPWR is confirmed ROHS3 compliant with MSL Level 1 rating. RoHS and MSL specifications for HEF40175BTT,118 are not provided in the available documentation.

Q: Can HEF40175BTT,118 be used in applications designed for 18V supply voltage? A: No. The HEF40175BTT,118 maximum supply voltage is 15V. Applications requiring 18V operation must use CD40175BPWR or CD40175BPW.

Q: What is the significance of the 16-TSSOP package specification? A: The 16-TSSOP (Thin Shrink Small Outline Package) with 0.173" width and 4.40mm body width is the standard surface mount package for all three parts. This ensures mechanical and electrical compatibility at the PCB level without requiring layout modifications.
