Product details

The Texas Instruments SN74LVC1G99DCTT is a single-circuit configurable multiple-function gate from the 74LVC series. This part is used for board-level glue logic where a single gate needs to implement multiple logic functions (AND, OR, NAND, NOR, XOR, etc.) by changing the input configuration, saving board space and reducing part count in industrial, automotive, and telecom equipment.

SM8 package — footprint and storage

Housed in an 8-lead SM8 package (8-LSSOP / 8-MSOP, 2.80 mm width), this is a surface-mount device that fits tight layouts.

Frequently asked questions

Does SN74LVC1G99DCTT support 5V logic?

Yes — the supply voltage range of 1.65 V to 5.5 V includes 5 V, so it can interface directly with 5 V logic families.

What is the function of the SN74LVC1G99DCTT?

It is a configurable multiple-function gate — a single logic gate that can be set to perform AND, OR, NAND, NOR, XOR, or other functions by changing the input connections, reducing the number of unique part numbers needed on a board.
