VS3V253 Datasheet | Vaishali Semiconductor

Description The VS3V253 is a high-speed LVTTL- patible dual 4:1 multiplexer/demultiplexer. The VS3V2253 contains two mux/demux channels with mon path control (S0 & S1) and individual active LOW enables /EA and /EB. The low ON resistance of VS3V253 allows inputs to be connected to outputs without adding propagation delay and without generating additional signal noise. The VS3V2253 has 25Ω resistors in series with the switches to reduce ground-bounce noise and signal reflections. The VS3V253 and VS3V2253 mux/demux switches are designed for 3.3V to 2.5V, or 2.5V to 1.8V translation, without any external ponents. These switches also offer very high impedance between switch terminals in the power off or ‘disabled’ state. This feature , bined with near-zero propagation delay in the ‘on’ state, makes VS3V253 and VS3V2253 ideal interface elements for hot-swapping applications. 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 (VS3V253) and 25Ω (VS3V2253) Pin-patible with 74LVC253 or equivalent logic devices Zero added ground bounce or signal noise - = - = - = - = - = Break-before-make feature Undershoot clamp diodes on all switch and control pins ESD rating >2000V (Human Body Model) or >200V (Machine Model) Latch-up current >100m A Available in 150-mil wide QSOP package - = - = Figure 1.
