Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 74LVC2245AD,118 is determined by the following critical parameters: logic type (transceiver, non-inverting), functional configuration (1 element, 8 bits per element), output type (3-state), package form factor (20-SOIC with 0.295" width, 7.50mm), surface mount capability, and compliance certifications (RoHS3, REACH unaffected). All identified substitute parts maintain these core electrical and mechanical specifications. Variations in output current capability (12mA versus 24mA), supply voltage minimum threshold (1.2V versus 1.65V), series designation (74LVC, 74LVCH, 74LVCR), and packaging format (Tape & Reel, Cut Tape, Tube) do not preclude functional substitution when these parameters fall within acceptable design tolerances. The substitute parts are grouped by manufacturer (Texas Instruments) and series family while maintaining identical pinout and functional behavior.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain active product status and full RoHS3 compliance with REACH unaffected designation, ensuring regulatory alignment with the primary 74LVC2245AD,118 device. Selection among substitute options depends on specific design requirements and supply constraints. The SN74LVC245ADWR and SN74LVCH245ADWR variants offer the highest inventory availability (100200 Pcs and 22063 Pcs respectively) and are available in Cut Tape and Digi-Reel packaging formats suitable for automated assembly processes. The SN74LVCR2245ADW and SN74LVCR2245ADWR maintain identical output current specifications (12mA / 12mA) matching the primary part, with the ADWR variant providing Tape & Reel packaging. All substitute parts operate within the -40°C to 125°C temperature range and maintain the 20-SOIC package footprint, ensuring PCB layout compatibility. Supply voltage minimum specifications vary between 1.2V (primary part) and 1.65V (all substitutes); designs operating below 1.65V require confirmation of the primary part's continued availability.

Frequently Asked Questions (FAQ)

Q: Can SN74LVC245ADWR be used as a direct replacement for 74LVC2245AD,118?

A: Yes. Both parts share identical logic type (transceiver, non-inverting), functional configuration (1 element, 8 bits per element), 3-state output, 20-SOIC package footprint, and operating temperature range (-40°C to 125°C). The primary difference is output current capability: SN74LVC245ADWR provides 24mA versus 12mA for the primary part. This higher current capacity is compatible with designs specified for 12mA output. The minimum supply voltage for SN74LVC245ADWR is 1.65V compared to 1.2V for the primary part; verify your design does not operate below 1.65V.

Q: What is the difference between 74LVCH and 74LVCR series substitutes?

A: Both 74LVCH (SN74LVCH245ADW, SN74LVCH245ADWR) and 74LVCR (SN74LVCR2245ADW, SN74LVCR2245ADWR) series maintain the same functional specifications as the primary part. The 74LVCH series provides 24mA output current, while 74LVCR series matches the primary part at 12mA output current. Both series operate with 1.65V minimum supply voltage. Series selection depends on output current requirements and inventory availability for your specific packaging format preference.

Q: Are packaging format differences (Tube, Cut Tape, Tape & Reel) electrically significant?

A: No. Packaging format differences (Tube, Cut Tape & Digi-Reel, Tape & Reel) are logistics and assembly considerations only. All formats contain electrically identical components. Selection depends on your manufacturing process: Tape & Reel and Cut Tape formats support automated pick-and-place assembly, while Tube format is suitable for manual assembly or lower-volume applications.

Q: Can I use SN74LVCH245ADWR in a design specified for 1.2V minimum supply voltage?

A: No. SN74LVCH245ADWR specifies a minimum supply voltage of 1.65V, while the primary 74LVC2245AD,118 operates down to 1.2V. If your design requires operation below 1.65V, the primary part or equivalent parts with matching 1.2V minimum specification must be used. Verify all substitute part datasheets for supply voltage compatibility before design implementation.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All identified substitute parts (SN74LVC245ADW, SN74LVC245ADWR, SN74LVCH245ADW, SN74LVCH245ADWR, SN74LVCR2245ADW, SN74LVCR2245ADWR) maintain RoHS3 compliance and REACH unaffected status, matching the regulatory certification of the primary 74LVC2245AD,118 part.
