VS3V257 - High-speed 3.3V CMOS VSwitch Quad 2:1 Mux/Demux

General Description

The VS3V257 is a high-speed LVTTL

compatible Quad 2:1 multiplexer/demultiplexer.

The VS3V257 contains four mux/demux channels, with a common path control (S) and active low enable (/E).

Key Features

  • =.
  • = Enhanced N-FET with no DC path to VCC or GND in normal operating signal voltage range. Low impedance switches connect inputs to outputs with near-zero propagation delay: 5Ω (VS3V257) and 25Ω (VS3V2257) Pin-compatible with 74LVC257 or equivalent logic devices Zero added ground bounce or signal noise.

The VS3V257 contains four mux/demux channels, with a common path control (S) and active low enable (/E). The low ON resistance of the VS3V257 allows inputs to be connected to outputs, without adding propagation delay and without generating additional signal noise. The VS3V2257 has 25Ω resistors in series with the switches to reduce ground-bounce noise and signal reflection. The VS3V257 and VS3V2257 are designed for 3.3V to 2.5V or 2.5V to 1.
