description/ordering information

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

12 ns.
