SN7406DR standard TTL logic integrated circuit

The SN7406DR from Texas Instruments is a standard TTL logic integrated circuit belonging to the hex inverter/buffer family. It features six independent channels, each with a high-voltage open-collector output capable of sinking up to 40mA. This device operates from a nominal 5V supply (4.75V to 5.25V) and is designed for high-speed operation with typical propagation delays in the 10-50ns range. Its bipolar input structure and open-drain outputs make it ideal for interfacing between TTL logic levels and higher voltage circuits, such as driving lamps, relays, or acting as a simple level shifter. The SOIC-14 package offers a compact footprint for board space-constrained designs, and its catalog rating with an operating temperature range of 0°C to 70°C suits a wide array of commercial and industrial control systems, logic signal inversion, and buffer driver applications.
