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

transmitted in either direction.

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

impedance state with respect to the output. Make-before-

break is guaranteed. An eptiaxial layer prevents latch-up.
