SN54HC298, SN74HC298
Quadruple 2-Input Multiplexer With Storage
This quadruple two-input multiplexer with storage provides essentially the equivalent functional
capabilities of two separate MSI functions (‘HC157 and ‘HC175) in a single 16-pin package.
When the Word-Select (WS) input is low, word one (A1, B1, C1, D1) is applied to the flip-flops. A high
Word-Select input causes word two (A2, B2, C2, D2) to be selected. The selected word is clocked tot
he output terminals on the negative-going edge of the clock pulse.
