Overview
The SN7407DRG4 is a hex buffer and driver integrated circuit produced by Texas Instruments. This device is part of the SN74x7 series, which features high-voltage open-collector outputs, making it suitable for interfacing with high-level circuits such as MOS or for driving high-current loads like lamps or relays. The SN7407DRG4 is particularly useful for converting TTL voltage levels to MOS levels and is characterized for use as buffers for driving TTL inputs.
The device is available in a 14-pin SOIC package and operates within a temperature range of 0 to 70°C. It is fully compatible with most TTL circuits and has inputs that are diode-clamped to minimize transmission-line effects, simplifying design processes.
