Description

The DG527, DG528, and DG529 are CMOS monolithic 16 channel/dual 4 channel analog multiplexers. Each device has on-chip address and control latches to simplify design in microprocessor based applications. The DG526 uses 4 address lines to control its 16 channels; the DG527, DG528 both use 3 address lines to control their 8 channels; and the DG529 uses 2 address lines to control its 4 channels. The enable pin is used to enable the address latches during the WR pulse. It can be hard wired to the logic supply if one of the channels will always be used (except during a reset) or it can be tied to address decoding circuitry for memory mapped operation. The RS pin is used to clear all latches regardless of the state of any other latch or control line. The WR pin is used to transfer the state of the address control lines to their latches, except during a reset or when EN is low. A channel in the ON state conducts signals equally well in both directions. In the OFF state each channel blocks voltages up to the supply rails. The address inputs, WR, RS and the enable input are TTL and CMOS compatible over the full specified operation temperature range.
