description

These monolithic 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 has a

rated output voltage of 30 V and the

′LS17 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.

The SN54LS07 is characterized over the full military temperature range of –55

°C to 125°C. The SN74LS07 and

SN74LS17 are characterized for operation from 0

°C to 70°C.
