The DM74LS366AN is a Hex Tri-State Inverter Buffer with common enable, belonging to the low-power Schottky (LS) TTL family of integrated circuits. Manufactured by National Semiconductor (now Texas Instruments), it provides six inverting buffers with a common enable input that controls whether the outputs are enabled or in a high-impedance state.

Applications:

• Bus drivers.
• Memory address decoding.
• Data multiplexing.
• Logic level conversion.
• Isolation buffers.

Features:

• Hex inverting buffers.
• Tri-state outputs.
• Common enable input.
• Low-power Schottky (LS) technology.
• Operating voltage: 4.75V to 5.25V.
• Typical propagation delay of 18 ns.

Benefits:

• Tri-state outputs allow multiple devices to share a common bus without contention.
• Common enable input simplifies control of the buffers.
• Inverting buffers provide a logic inversion function.
• Low power consumption reduces overall system power requirements.
• TTL compatibility ensures easy integration with other TTL logic devices.

Additional Details:

The DM74LS366AN is available in a 16-pin DIP (Dual In-Line Package). When the enable input is LOW, the outputs of the inverters are enabled and follow the inverse of the inputs. When the enable input is HIGH, the outputs are in a high-impedance state, effectively disconnecting them from the bus. This allows other devices to drive the bus without interference. The LS technology provides a good balance between speed and power consumption, making the DM74LS366AN suitable for a variety of applications where tri-state buffering is required.
