Overview
The SN7407DR is a six-channel TTL hex buffer and driver produced by Texas Instruments. This device is designed to interface with high-level circuits, such as MOS circuits, or to drive high-current loads like lamps or relays. It features high-voltage open-collector outputs and is characterized for use as buffers for driving TTL inputs. The SN7407DR is part of the SN74x7 family, which includes devices with high sink current capability and compatibility with most TTL families.
