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 鈥淭鈥?switches, resulting in
wide bandwidth, low crosstalk and high 鈥渙ff鈥?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
