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 SN74LS07 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
