A data input device in a semiconductor device, includes a data strobe signal input buffer, which driven in response to a selection signal of a data input/output mode, for receiving a data strobe signal; a data input buffer driven in response to the selection signal; a repeater, which receives the selection signal and the data strobe signal input, outputs a first control signal of a first logic level when the selection signal is activated, and a second control signal of a second logic level when the selection signal is inactivated; and a latch for latching data provided from the data input buffer in response to the first control signal outputted from the repeater, wherein the latch is disabled when the second control signal is provided from the repeater.
