Product details

What this hex inverter with open-drain outputs does

The SN74AHC05PW is a hex inverter with open-drain outputs in a 14-TSSOP package. The supply voltage range spans 2V to 5.5V, covering 3.3V and 5V logic families cleanly. Quiescent current is a maximum of 2 µA, so it fits into battery-powered or always-on subsystems without draining the rail. Each output can sink up to 8 mA, enough to drive a standard LED or a low-power optocoupler directly. Propagation delay is 7.5 ns at 5V with a 50 pF load.

Package is 14-TSSOP with 4.40 mm body width. Supplier device package is 14-TSSOP. Surface-mount.

Frequently asked questions

Does SN74AHC05PW have open-drain outputs?

Yes, the SN74AHC05PW has open-drain outputs. Each of the six inverters can sink current but cannot source current; an external pull-up resistor is required to bring the output high.
