description
These monolithic 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 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.
The SN5407 and SN5417 are characterized for operation over the full military temperature range of –55°C to
125°C. The SN7407 and SN7417 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 af fect 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.
