DG3157A, DG3157B

Vishay Siliconix

Low Voltage, 300-MHz - 3 dB Bandwidth, SPDT Analog Switch with

Power Down Protection

(2:1 Multiplexer/Demultiplexer Bus Switch)

DESCRIPTION

FEATURES

The DG3157A, DG3157B are high-speed single-pole

double-throw, low voltage switch. Using sub-micro CMOS

technology, the DG3157A, DG3157B achieves low on-

resistance and negligible propagation delay. The DG3157A,

DG3157B can handle both analog and digital signals and

permits signals with amplitudes of up to V_CCto be

transmitted in either direction. Select pin of control logic input

can be over the V+. 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 A pin.

Break before make is guaranteed. The DG3157A has an

internal pull down resistor on the control pin S, while the

DG3157B does not.
