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.
