description
These monolithic TTL hex buffersldrivers feature high-voltage open-collector Outputs for interfacing with high-level circuits
(such as MOSJ, or for driving high-currenr loads (such as lamps or relaysl, and are also characterized for use as buffers for
driving XL inputs. The SN5407 and SN7407 have minimum breakdown voltages of 30 Volts and the SN5417 and SN7417
have minimum breakdown voltages of 15 volts. The maximum sink current is 30 milliamperes for the SN5407 and SN541 7,
and 40 milliamperes for the SN7407 and SN74 17.
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 milliwatts and average propagation delay time is 14 nano-
seconds. The SN5407 and SN541 7 are characterized for Operation over the full milttary temperature range of -55 “C to 125 “C;
the SN7407 and SN7417 are characterized for Operation from 0 “C to 70 ‘C.
