This quadruple two-input multiplexer with storage provides essentially the equivalent functional capabilities of two separate MSI functions in a single 16-pin package. When the Word-Select (WS) input is low, word one is applied to the flip-flops. A high Word-Select input causes word two to be selected. The selected word is clocked to the output terminals on the negative-going edge of the clock pulse. While the SN54HC298 is functional over the full military temperature range, the SN74HC298 is characterized for operation over industrial temperature ranges (-40°C to +85°C)
