Texas Instruments SN74LV240A 8-bit buffer/driver is designed to improve the performance and density of clock drivers, tri-state memory address drivers, and bus-oriented receivers and transmitters. These devices have inverting outputs and operate from 2 V to 5.5 V VCC. The SN74LV240A is configured as two 4-bit buffers/line drivers with independent output enable inputs. All ports support mixed-mode voltage operation. Typical applications include smartphones, network switches, and wearable devices.
