1 mm x 1.2 mm
Wide operation voltage range: 1.8 V to 5.5 V
Useful in both analog and digital signal
switching
300 MHz - 3 dB bandwidth
Power down safe design
Low voltage logic threshold:
Vth(high) = 1.2 V at V+ = 3.3 V
Minimal propagation delay
Break-before-make switching
Zero bounce in flow-through mode
> 300 mA latch up current per JESD78
> 8 kV ESD/HBM
DG3157A version has internal pull down resistor on
control pin S
DESCRIPTION
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 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.
