DIP Quad 2-Input NAND Gate With Open Drain Outputs 7403
This device contains four independent 2-input NAND gates. A key feature of this chip is its open-drain outputs , which allows the output to sink current to ground but not source current. This makes it highly versatile for applications like level shifting or creating wired-AND logic.
Features
Wide Operating Voltage Range: 2 V to 6 V
Open-Drain Outputs: Allows for flexible use in mixed-voltage systems and wired-AND configurations.
Low Power Consumption: 20-μΑ maximum ICC
Good Performance: Typical tpd = 8 ns at 5 V
Low Input Current: 1 µA maximum
Drive Capability:
Outputs can drive up to 10 LSTTL loads
±4-mA output drive at 5 V
