说明

The SN74LV8151 is a 10-bit universal Schmitt-trigger buffer with 3-state outputs, designed for 2-V to 5.5-V V_CC operation. The logic control (T/C\) pin allows the user to configure Y1 to Y8 as noninverting or inverting outputs. When T/C\ is high, the Y outputs are noninverted (true logic ), and when T/C\ is low, the Y outputs are inverted (complementary logic).

When output-enable (OE)\ input is low, the device passes data from Dn to Yn. When OE\ is high, the Y outputs are in the high-impedance state. The path A to P is a simple Schmitt-trigger buffer, and the path B to N is a simple Schmitt-trigger inverter.

This device is fully specified for partial-power-down applications using I_off. The I_off circuitry disables the outputs, preventing damaging current backflow through the device when it is powered down.
