HEF4050BT

Hex non-inverting buffers

The HEF4050B provides six non-inverting buffers with high current output capability suitable for driving TTL or high capacitive loads. Since input voltages in excess of the buffers’ supply voltage are permitted, the buffers may also be used to convert logic levels of up to 15 V to standard TTL levels.

It operates over a recommended VDD power supply range of 3 V to 15 V referenced to VSS (usually ground). Unused inputs must be connected to VDD, VSS, or another input.

Sample

As a Nexperia customer you can order samples via our sales organization or directly via our Online Sample Store: https://extranet.nexperia.com.

Sample orders normally take 2-4 days for delivery.

If you do not have a direct account with Nexperia our network of global and regional distributors is available and equipped to support you with Nexperia samples.

How does it work?

The interactive datasheets are based on the Nexperia MOSFET precision electrothermal models. With our interactive datasheets you can simply specify your own conditions interactively. Start by changing the values of the conditions. You can do this by using the sliders in the condition fields. By dragging the sliders you will see how the MOSFET will perform at the new conditions set.
