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.

Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTES: 1. Voltage values are with respect to network ground terminal.
2. This is the maximum voltage that should be applied to any output when it is in the off state.
