Diodes 74LVC1G98 User Manual

74LVC1G98

Description

The 74LVC1G98 is a single 3-input positive configurable multiple
function gate with a standard push-pull output. The output state is
determined by eight patterns of 3-bit input. The user can chose the
logic functions MUX, AND, OR, NAND, NOR, inverter or non­inverting buffer. All inputs can be connected to ground or V
required. The device is designed for operation with a power supply
range of 1.65V to 5.5V. The inputs are tolerant to 5.5V allowing this
device to be used in a mixed voltage environment. The device is
fully specified for partial power down applications using IOFF. The
IOFF circuitry disables the output preventing damaging current
backflow when the device is powered down. The user is reminded
that the device can simulate several types of logic gates but may
respond differently due to the Schmitt action at the inputs.
