Product Summary
The SN74LVC1G18DCKR is a 1-of-2 noninverting demultiplexer with a 3-state output. The SN74LVC1G18DCKR buffers the data on input A and passes it to either output Y0 or Y1, depending on whether the state of the select (S) input is low or high, respectively. The SN74LVC1G18DCKR is designed for 1.65-V to 5.5-V VCC operation.
