The SN74x7 is a high sink current capable open-collector buffer. This device is high-voltage tolerant on the output of up to 30 V on the SNx407 model and 15 V on the SNx417 model. The SN74x7 is also useful for converting TTL voltage levels to MOS levels.
The SNx407 and SNx417 devices are ideal for high voltage outputs. The SNx407 device has a maximum output voltage 30 V and the SNx417 device has a maximum output voltage 15 V.
The high sink current is up to 40 mA for the SN74x7.
Table 1 lists the functions of the devices.
