Overview
The SN74LV8151PWR is a 10-bit universal Schmitt-trigger buffer with 3-state outputs, designed and manufactured by Texas Instruments. This device is optimized for operation over a wide voltage range of 2 V to 5.5 V, making it versatile for various digital logic applications. The SN74LV8151 features a logic control pin (T/C\) that allows users to configure the outputs as either noninverting or inverting, providing flexibility in logic implementation. The device also includes output-enable (OE\) input, which controls the high-impedance state of the outputs, and supports partial-power-down mode operation using I\off circuitry.
