Description

The DG526, DG527, DG528, and DG529 are CMOS

Monolithic 16-Channel/Dual 4-Channel Analog Multiplexers.

Each device has on-chip address and control latches to sim-

plify 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 volt-

ages 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.
