SN74LVC1G99中文资料具有三态输出的超级可配置多功能门数据手册TI规格书

描述 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.
