DESCRIPTION

The DG3157A, DG3157B are high-speed single-pole

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

technology, the DG3157A, DG3157B achieves low onresistance

and negligible propagation delay. The DG3157A,

DG3157B can handle both analog and digital signals and

permits signals with amplitudes of up to VCC to be

transmitted in either direction. Select pin of control logic input

can be over the V+. When the select pin is low, B0 is

connected to the output A pin. When the select pin is high,

B1 is 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.
