Parameter Comparison

Engineering Selection Recommendations

Both the CD74FCT245M96 and 74FCT2245ATSOG8 maintain active product status and ROHS3 compliance, confirming ongoing manufacturer support and regulatory alignment. The substitute part demonstrates electrical compatibility across all specified supply voltage and logic parameters.

The 74FCT2245ATSOG8 exhibits an extended operating temperature range (-40°C ~ 85°C) compared to the main part (0°C ~ 70°C), providing broader thermal operational capability. Output low current differs between the two parts (64mA versus 12mA), which may influence circuit design considerations in applications with specific current-sinking requirements.

Selection between these parts should be based on application-specific thermal requirements and output current specifications within the defined operating envelope.

Frequently Asked Questions (FAQ)

Q: Can the 74FCT2245ATSOG8 directly replace the CD74FCT245M96 in existing designs?

A: Yes, both parts share identical logic type, element configuration, bit width, output type, package form factor, and supply voltage specifications. Direct pin-compatible substitution is supported.

Q: What is the significance of the different operating temperature ranges?

A: The CD74FCT245M96 operates from 0°C to 70°C, while the 74FCT2245ATSOG8 operates from -40°C to 85°C. Applications requiring operation below 0°C or above 70°C must use the substitute part. Applications within the 0°C to 70°C range are compatible with both.

Q: How do the output current specifications differ between these parts?

A: Output high current is identical at 15mA. Output low current differs: CD74FCT245M96 provides 64mA, while 74FCT2245ATSOG8 provides 12mA. Circuit designs requiring higher current sinking capability should verify compatibility with the lower output current of the substitute.

Q: Are both parts RoHS compliant?

A: Yes, both the CD74FCT245M96 and 74FCT2245ATSOG8 are ROHS3 compliant, meeting environmental and regulatory requirements.

Q: Do these parts use the same package?

A: Yes, both parts use the 20-SOIC (0.295", 7.50mm Width) surface mount package, ensuring mechanical and footprint compatibility.
