DESCRIPTION

The DG3157 is a high-speed single-pole double-throw, low

power, TTL-Compatible bus switch. Using sub-micro CMOS

technology, the DG3157 achieves low on-resistance and

negligible propagation delay.

The DG3157 can handle both analog and digital signals and

permits signals with amplitudes of up to VCC to be

transmitted in either direction.

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 highimpedance

state with respect to the output. Make-beforebreak

is guaranteed. An eptiaxial layer prevents latch-up.
