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.
· Built on a D/CMOS process, combining n-channel DMOS switching FETs with low-power CMOS control logic, drivers, and latches.
· Features on-chip TTL-compatible address decoding logic and latches with data readback for simplified microprocessor data bus interfacing.
· Low on-resistance and low capacitance make it ideal for wideband data multiplexing and video/audio signal routing.
· Includes an optional negative supply pin for handling bipolar signals without DC biasing.

FEATURES

· Wide Bandwidth: 500 MHz.
· Very Low Crosstalk: –97 dB @ 5 MHz.
· On-Board TTL-Compatible Latches with Readback.
· Low rDS(on): 45 Ω.
· Single-Ended or Differential Operation.
· Latch-up Proof.
· Improved System Bandwidth and Channel Off-Isolation.
· Simplified Logic Interfacing and High-Speed Readback.
· Allows Bipolar Signal Swings and Differential Signal Switching.
· Reduced Insertion Loss.
