Additional Details

The TC74LVX125F features independent enable pins for each of the four buffer gates, providing flexibility in controlling data flow. The output is high when the enable input is high and follows the data input when the enable input is low. The device is available in a small outline package (SOP), making it suitable for surface-mount applications. The operating temperature range is -40°C to +85°C.
