Powered-off Protection, High Speed, 1.65 V to 5.5 V, SPDT Analog

Switch (2:1 Multiplexer / Demultiplexer Bus Switch)

DESCRIPTION

FEATURES

Pl5A3157, and STG3157

The DG3157E is a high speed single-pole double-throw

analog switch designed for +1.65 V to +5.5 V single power

rail operation.

industry

standard

Fabricated with high density CMOS technology, the

DG3157E achieves low on-resistance, fast switching speed,

and high bandwidth while maintains low power

consumption.

• Low switch on-resistance (6 Ω)

• +1.65 V to +5.5 V single supply operation

• Powered-off protection

The DG3157E can handle both analog and digital signals

and permits signals with amplitudes of up to V+ to be

transmitted in either direction.

When the select pin is low, B₀is connected to the output A

pin. When the select pin is high, B₁is connected to the

output A pin. The path that is open will have a high

impedance state with respect to the output. Break before

make switching performance is guaranteed.

A powered-off protection circuit is built into the switch to

prevent an abnormal current flow from COM pin to V+ during

the power-down condition. Each output pin can withstand

greater than 7 kV (human body model).

• Control logic inputs can go over V+ up to 5.5 V

• Low parasitic capacitance, 7 pF at switch off

• Break before make switching

• Latch-up performance exceeds 200 mA per JESD 78

• High ESD rating

- 7000 V human body model (JS-001)

- 1000 V charge device model (JS-002)

• Material categorization: for definitions of compliance
