DESCRIPTION

The DG535/536 are 16-channel multiplexers designed for routing one of 16 wideband analog or digital input signals to a single output. They feature low input and output capacitance, low on-resistance, and n-channel DMOS "T" switches, resulting in wide bandwidth, low crosstalk and high "off" isolation. In the on state, the switches pass signals in either direction, allowing them to be used as multiplexers or as demultiplexers. and a low 75-mW power consumption vastly reduces power supply requirements.

Theses devices are built on a proprietary D/CMOS process which creates low-capacitance DMOS FETs and high-speed, low-power CMOS logic on the same substrate.

On-chip address latches and decode logic simplify microprocessor interface. Chip Select and Enable inputs simplify addressing in large matrices. Single-supply operation
