Analog CMOS

Latchable Multiplexers

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 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
the state of any other latch or control line. The
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,
the enable input are TTL and CMOS compatible over the full
specified operation temperature range.

RS pin is used to clear all latches regardless of

WR pin is used
