DESCRIPTION
The SN74LVC1G99 device is operational from 1.65 V
to 5.5 V.
The SN74LVC1G99 device 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.
NanoFree™ package technologies are a major
breakthrough in IC packaging concepts, using the die
as the package.
