description/ordering information  
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 . The I circuitry disables the outputs,

off  
preventing damaging current backflow through the device when it is powered down.  
To ensure the high-impedance state during power up or power down, OE should be tied to V  
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
