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
off
. The I
off
circuitry disables the outputs,
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
CC
through a pullup
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
