SN74AUP1G99DCUT

Gates And Inverters - Multi-Function, Configurable Overview

The SN74AUP1G99DCUT is a low-power ultra-configurable multiple-function gate with three-state outputs, manufactured by Texas Instruments. It operates within a supply voltage range of 0.8 V to 3.6 V and supports an operating temperature from -40°C to +85°C. The device features Schmitt-trigger inputs and an input-disable function. Key electrical parameters include a maximum propagation delay of 7.4 ns at 3.3 V, typical power dissipation capacitance of 5 pF, and output currents up to ±4 mA. It is housed in an 8-pin VSSOP (DCU) package.

Gates And Inverters - Multi-Function, Configurable Procurement Notes

Verify the specific ordering suffix 'T' indicates a small tape-and-reel quantity of 250 units, distinct from standard reel quantities. Confirm the DCU package designation matches the required VSSOP footprint. Ensure RoHS compliance and lead finish specifications align with assembly requirements. Cross-reference the active production status on official manufacturer channels before finalizing procurement.

Gates And Inverters - Multi-Function, Configurable Selection Notes

Select this component when a single gate must perform multiple logic functions or act as a configurable multiplexer. The wide voltage range suits battery-powered portable applications. Verify that the required number of inputs does not exceed the four available control/data pins. Consider the three-state capability if bus isolation is necessary.

Gates And Inverters - Multi-Function, Configurable FAQ

How are the logic functions selected?

Logic functions are determined by the 4-bit pattern applied to the inputs A, B, C, and D. There are 16 possible combinations that configure the gate for specific operations like MUX, AND, or XOR.

What is the purpose of the OE pin?

The Output Enable (OE) pin controls the three-state output. When OE is high, the output is disabled (high-impedance). When OE is low, the output state is determined by the configured logic function.
