description/ordering information (continued)
These circuits are completely compatible with most TTL families. Inputs are diode clamped to minimize
transmission-line effects, which simplifies design. Typical power dissipation is 145 mW, and average
propagation delay time is 14 ns.

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. All voltage values are with respect to GND.
2. This is the maximum voltage that should be applied to any output when it is in the off state.
3. The package thermal impedance is calculated in accordance with JESD 51-7.

description/ordering information
These TTL hex buffers/drivers feature high-voltage open-collector outputs for interfacing
with high-level circuits (such as MOS) or for driving high-current loads (such as lamps or
relays) and also are characterized for use as buffers for driving TTL inputs. The SN5407 and
SN7407 have minimum breakdown voltages of 30 V, and the SN5417 and SN7417 have
minimum breakdown voltages of 15 V. The maximum sink current is 30 mA for the SN5407
and SN5417 and 40 mA for the SN7407 and SN7417.
These devices perform the Boolean function Y = A in positive logic.
