PRODUCT DESCRIPTION

To extend the number of switches in the array, you may cascade

multiple AD75019s. The SOUT output is the end of the shift

AD75019.

The AD75019 contains 256 analog switches in a 16 × 16 array.

Any of the X or Y pins may serve as an input or output. Any or

all of the X terminals may be programmed to connect to any or

all of the Y terminals. The switches can accommodate signals

with amplitudes up to the supply rails and have a typical on-

resistance of 150 Ω.

The AD75019 is fabricated in Analog Devices’ BiMOS II

process. This epitaxial BiCMOS process features CMOS

devices for low distortion switches and bipolar devices for

ESD protection.

Data is loaded serially via the SIN input and clocked into an on-

board 256-bit shift register via SCLK. When all the switch set-

tings have been programmed, data is transferred into a set of

256 latches via PCLK. The serial shift register is dynamic, so

there is a minimum clock rate of 20 kHz. The maximum clock

rate of 5 MHz allows loading times as short as 52 µs. The switch

control latches are static and will hold their data as long as power

is applied.
