DG9461DY-T1-E3

Analog Switches, Multiplexers, Demultiplexers Overview

The DG9461DY-T1-E3 is a low-voltage single-pole/double-throw (SPDT) analog switch manufactured by Vishay Siliconix. It operates on a +2.7 V to +5 V supply and features a maximum on-resistance of 40 Ω at 5 V. The device provides fast switching with turn-on and turn-off times of 35 ns and 20 ns, respectively. It exhibits low leakage current (200 pA max) and minimal charge injection (1 pC). Built on BCD-15 CMOS technology, it includes ESD protection exceeding 2000 V and guarantees break-before-make operation. The component is housed in an SOIC-8 package.

Analog Switches, Multiplexers, Demultiplexers FAQ

Does the DG9461 support dual power supplies?

No, the DG9461 is designed for single-supply operation ranging from +2.7 V to +5 V.

What is the guaranteed behavior during switching transitions?

Break-before-make operation is guaranteed to prevent short circuits between the common terminal and both throw terminals.

How does the device handle input signals exceeding the supply voltage?

Signals on the COM, NO, or NC pins exceeding V+ will be clamped by internal diodes, requiring forward diode current limits to be observed.
