DESCRIPTION  
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.  
For more information refer to Vishay Siliconix applications  
note AN502.
