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 V
CC
to be transmitted
in either direction.
When the Select pin is low, B
0
is connected to the output A pin.
When the Select pin is high, B
1
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.
