These hex buffers/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 ’LS07 devices have a rated output voltage of
30 V, and the SN74LS17 has a rated output voltage of 15 V. The maximum sink current is 30 mA for the
SN54LS07 and 40 mA for the SN74LS07 and SN74LS17.
These circuits are compatible with most TTL families. Inputs are diode-clamped to minimize transmission-line
effects, which simplifies design. Typical power dissipation is 140 mW, and average propagation delay time is
