Product data sheet

1. General description

The 74LVC1G99 provides a low voltage, ultra-conï¬gurable, multiple function gate with

3-state output. The device can be conï¬gured as one of several logic functions including,

AND, OR, NAND, NOR, XOR, XNOR, inverter, buffer and MUX. No external components

are required to conï¬gure the device as all inputs can be connected directly to VCC or GND.

The 3-state output is controlled by the output enable input (OE). A HIGH level at OE

causes the output (Y) to assume a high-impedance OFF-state. When OE is LOW, the

output state is determined by the signals applied to the Schmitt-trigger inputs (A, B, C and

D).

Due to the use of Schmitt-trigger inputs the device is tolerant of slowly changing input

signals, transforming them into sharply deï¬ned, jitter free output signals. By eliminating

leakage current paths to VCC and GND, the inputs and disabled output are also

over-voltage tolerant, making the device suitable for mixed-voltage applications.

This device is fully speciï¬ed for partial power-down applications using IOFF.

The IOFF circuitry disables the output, preventing the damaging backï¬ow current through

the device when it is powered down.

The 74LVC1G99 is fully speciï¬ed over the supply range from 1.65 V to 5.5 V.
