Key Parameters

Substitute Part Grouping Explanation

Substitution of the SN74HC04DBRG4 is determined by strict equivalence across the following critical parameters:

• Logic function: 6-channel inverter with single input per channel
• Electrical specifications: 2V ~ 6V supply voltage, 2 µA quiescent current, 5.2mA output current, 16ns propagation delay at 6V with 50pF load
• Input/output logic levels: Low 0.5V ~ 1.8V, High 1.5V ~ 4.2V
• Operating temperature range: -40°C ~ 85°C
• Package type: 14-SSOP surface mount
• Compliance: ROHS3 compliant, MSL Level 1

The SN74HC04DBR meets all these criteria and is classified as a parametric equivalent. The primary distinction is packaging format and product status.

Parameter Comparison

Engineering Selection Recommendations

The SN74HC04DBR is a direct parametric equivalent to the SN74HC04DBRG4 across all electrical and mechanical specifications. Both parts are manufactured by Texas Instruments, share identical logic functionality, electrical performance, and thermal operating range. Both maintain ROHS3 compliance and MSL Level 1 rating.

The primary distinction is product status: the SN74HC04DBRG4 is discontinued at DiGi Electronics, while the SN74HC04DBR maintains active status. The SN74HC04DBR is available in both Cut Tape and Digi-Reel packaging formats, providing supply chain flexibility. For applications requiring the SN74HC04DBRG4, the SN74HC04DBR is the appropriate selection based on availability and compliance equivalence.

Frequently Asked Questions (FAQ)
