DG3157
Vishay Siliconix
High-Speed, Low r_ON, SPDT Analog Switch
(2:1 Multiplexer/Demultiplexer Bus Switch)
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, 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.
