Engineering Selection Recommendations

MFR Recommended Substitute: 74LVC4245APW,118

The 74LVC4245APW,118 from Nexperia USA Inc. is the manufacturer-recommended replacement. It maintains the same base product number (74LVC4245) and series designation, ensuring functional compatibility. This part is in active production status with unlimited moisture sensitivity rating (MSL 1). The primary difference is package format (24-TSSOP versus 24-SOIC), which requires PCB layout modification but provides equivalent electrical performance. Voltage specifications (VCCA 1.5V–5.5V, VCCB 1.5V–3.6V) and operating temperature range (-40°C to 125°C) support standard industrial applications. RoHS3 and REACH compliance are maintained.

Upgrade Substitute: SN74LVC8T245MDWREP

The SN74LVC8T245MDWREP from Texas Instruments offers enhanced specifications while maintaining the original 24-SOIC package footprint, eliminating PCB redesign requirements. This part provides wider supply voltage compatibility (1.65V–5.5V for both VCCA and VCCB) and extended operating temperature range (-55°C to 125°C). Higher output current capability (32mA) supports more demanding load conditions. Product status is active with established supply chain availability. RoHS3 compliance is confirmed.

Similar Substitutes for Specific Applications:

74LVX3245MTCX (onsemi): Suitable for applications requiring 3.3V to 5V translation with 24-TSSOP package. Operating temperature limited to -40°C to 85°C.
ADG3300BRUZ / ADG3308BRUZ-REEL7 (Analog Devices): Provide auto-direction sensing feature with 50Mbps data rate capability in 20-TSSOP package. Voltage range 1.15V–5.5V (VCCA) and 1.65V–5.5V (VCCB) supports low-voltage applications.
CAVC8T245QRHLRQ1 (Texas Instruments): Automotive-grade option (AEC-Q100 qualified) in 24-VFQFN package with restricted voltage range (1.2V–3.6V) suitable for automotive systems.

Frequently Asked Questions (FAQ)

Q: Can I directly replace 74LVC4245AD,118 with 74LVC4245APW,118 without PCB modification?

A: No. While both parts share the same base product number and electrical specifications, the package differs: 74LVC4245AD,118 uses 24-SOIC (0.295" width) while 74LVC4245APW,118 uses 24-TSSOP (0.173" width). PCB footprint and layout must be updated accordingly.

Q: What is the key difference between the Nexperia and Texas Instruments substitutes?

A: The 74LVC4245APW,118 (Nexperia) maintains the same voltage domain specifications as the obsolete part. The SN74LVC8T245MDWREP (Texas Instruments) provides unified voltage supply capability (both VCCA and VCCB accept 1.65V–5.5V) and retains the original 24-SOIC package, reducing redesign effort.

Q: Are the Analog Devices ADG3300 and ADG3308 series compatible with the original 74LVC4245AD,118?

A: These parts provide functional voltage translation with 8 channels and tri-state output. However, they use a 20-pin TSSOP package instead of 24-pin SOIC, requiring significant PCB redesign. They include auto-direction sensing and 50Mbps data rate capability, making them suitable for upgraded designs with different pinout requirements.

Q: Which substitute is best for automotive applications?

A: The CAVC8T245QRHLRQ1 from Texas Instruments is AEC-Q100 qualified for automotive use. However, its voltage range (1.2V–3.6V) is more restricted than the original part, limiting it to low-voltage automotive systems.

Q: Do all substitutes maintain RoHS3 compliance?

A: Yes. All listed substitute parts are RoHS3 compliant and REACH unaffected, matching the compliance status of the original 74LVC4245AD,118.

Q: What packaging options are available for the 74LVC4245 base product?

A: The 74LVC4245 base product is available in multiple packages: 24-SOIC (0.295" width), 24-TSSOP (0.173" width), and 24-SSOP (0.154" width). Package selection depends on PCB space constraints and manufacturing capabilities.
