These hex buffers and drivers feature high-voltage open-collector outputs to interface with high-level circuits or for driving high-current loads. They are also characterized for use as buffers for driving TTL inputs. The 74LS07 devices have a rated output voltage of 30 V. The maximum sink current is 40 mA.These circuits are compatible with most TTL families.Inputs are diode-clamped to minimize transmissionline effects, which simplifies design. Typical power dissipation is 140 mW, and average propagation delay time is 12 ns.
