The latches are level sensitive; therefore, has two CS inputs. This enables the device to be used either as a while WR is held low, the latches are transparent and the switches dual 16-to-1 channel multiplexer or a differential 16-channel respond to changing the address and enable the inputs. multiplexer. If a differential output is required, tie CSA and CSB together. Rev.
