The DG534A is a digitally selectable 4-channel or dual
2-channel multiplexer. The DG538A is an 8-channel or dual
4-channel multiplexer. On-chip TTL-compatible address
decoding logic and latches with data readback are included to
simplify the interface to a microprocessor data bus. The low
on-resistance and low capacitance of the these devices make
them ideal for wideband data multiplexing and video and audio
signal routing in channel selectors and crosspoint arrays. An
optional negative supply pin allows the handling of bipolar
signals without dc biasing.
The DG534A/DG538A are built on a D/CMOS process that
combines n-channel DMOS switching FETs with low-power
CMOS control logic, drivers and latches. The low-capacitance
DMOS FETs are connected in a “T” configuration to achieve
extremely high levels of off isolation. Crosstalk is reduced to
–97 dB at 5 MHz by including a ground line between adjacent
signal paths. An epitaxial layer prevents latch-up.
