DESCRIPTION/ORDERING INFORMATION
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 V_CC or GND.
This device functions as an independent inverter, but because of Schmitt action, it has different input threshold
levels for positive-going (V_T+) and negative-going (V_T–) signals.
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.
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.
