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.
