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 high-impedance state
with respect to the output. Make-before-break is guaranteed.
An eptiaxial layer prevents latch-up.
