Substitute Part Grouping Explanation

Substitute parts for the CD4049UBEE4 are identified based on strict electrical and mechanical parameter matching within the 4000B CMOS logic series. The substitution criteria are:

• Identical logic type (Inverter)
• Identical number of circuits (6 channels)
• Identical number of inputs (1 per channel)
• Matching supply voltage range (3V ~ 18V)
• Matching quiescent current specification (4 µA maximum)
• Matching output current ratings (4.3mA high, 24mA low)
• Matching input logic levels (Low: 1V ~ 2.5V, High: 4V ~ 12.5V)
• Matching propagation delay (50ns @ 15V, 50pF)
• Matching operating temperature range (-55°C ~ 125°C)
• Identical package type (16-DIP through-hole)
• Identical base product number (CD4049)
