Product details

Open-drain NAND gate for mixed-voltage and wired-OR buses

The SN74LVC1G38DCKR: The open-drain output pulls low only; the high level is set by an external pull-up resistor. Propagation delay is 3.9 ns at 5 V with a 50 pF load. The open-drain output sinks up to 32 mA.

What the open-drain output means for your design

Because the output is open-drain, there is no internal pull-up to VCC. The high-level voltage is determined by the pull-up resistor and its supply. The 32 mA sink current is the maximum the output can pull low. If you are driving a load that needs more than that — say a high-current LED or a heavy relay — buffer it with a transistor. The quiescent current is only 10 µA, so it adds negligible static power in battery-powered designs.

The SN74LVC1G38DCKR comes in a 5-lead SC-70 package (also known as SOT-353). It is a surface-mount part.

Frequently asked questions

What is the output type of SN74LVC1G38DCKR?

The output is open-drain. This is different from a standard push-pull output, which drives both high and low internally.

Can SN74LVC1G38DCKR be used as a level shifter?

Yes. Because the output is open-drain, you can pull it up to a different voltage than VCC. For example, run the gate at 3.3 V and pull the output up to 5 V to drive a 5 V input, or pull up to 1.8 V to interface with a low-voltage device. The pull-up resistor value should be chosen to meet the rise-time requirement of the receiving logic.

Is SN74LVC1G38DCKR RoHS compliant?

Yes, it is ROHS3 compliant.
