SN74LVC1G99QDCURQ1

具有三态输出超可配置的多功能的门 ULTRA-CONFIGURABLE MULTIPLE-FUNCTION GATE WITH 3-STATE OUTPUT

The SN74LVC1G99-Q1 is operational from 1.65 V to 5.5 V.

The SN74LVC1G99-Q1 features configurable multiple functions with a 3-state output. The output is disabled when the output-enable OE input is high. When OE is low, the output state is determined by 16 patterns of 4-bit input. The user can choose logic functions, such as MUX, AND, OR, NAND, NOR, XOR, XNOR, inverter, and buffer. All inputs can be connected to VCC or GND.

This device functions as an independent inverter, but because of Schmitt action, it has different input threshold levels for positive-going VT+ and negative-going VT– signals.

To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.

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