It takes a logic input and outputs its complement, with each output able to be placed into a high-impedance state via the output-enable controls. This makes it a standard choice for shared data buses where you need to invert a signal and then disconnect the driver when another device talks. The two enable pins map to two groups of buffers: one 2-bit and one 4-bit, giving flexible bus-width coverage. Supply range spans 2V to 6V, so it works on legacy 5V TTL rails and modern 3.3V logic supplies without a level translator. Output drive is 7.8 mA per pin — enough for a single TTL load or a few CMOS fan-outs, but not for driving a long backplane trace directly. There is no last-time-buy risk for current production. ## What the 7.8 mA output rating means for your bus The 7.8 mA high/low output current is typical for the 74HC family. It can drive one standard TTL load (about 1.6 mA) or several CMOS gate inputs (each a few microamps). If you need to drive a 50-ohm backplane or a long cable, you will need a bus transceiver with higher drive, such as the 74ABT or 74LVTH series. For on-board buffering between two logic ICs, this part is a clean fit.","metaTitle":"SN74HC368D TI Buffer, Inverting 3-State 16-SOIC","metaDescription":"Texas Instruments SN74HC368D hex inverting buffer with 3-state outputs. 2V–6V supply, -40°C to 85°C, 16-SOIC.
