FSTU3253 Dual 4:1 Multiplexer/Demultiplexer Bus Switch with −2V Undershoot Protection August 2001 Revised September 2001 FSTU3253 Dual 4:1 Multiplexer/Demultiplexer Bus Switch with −2V Undershoot Protection General Description Features The Fairchild Switch FSTU3253 is a dual 4:1 high-speedUndershoot hardened to −2.0V CMOS TTL-compatible multiplexer/demultiplexer bus4Ω switch connection between two ports switch. The low On Resistance of the switch allows inputs Minimal propagation delay through the switch to be connected to outputs without adding propagation Low l CC delay or generating additional ground bounce noise. Zero bounce in flow-through mode When OE is LOW, S and S connect the A Port to the 0 1 Control inputs compatible with TTL level selected B Port output. When OE is HIGH, the switch is OPEN and a high-impedance state exists between the twoSee application note AN-5008 and AN-5021 for details ports. on undershoot The A and B Ports are protected against undershoot to support an extended range to 2.0V below ground. Fairchild’s integrated Undershoot Hardened Circuit (UHC) senses undershoot at the I/O and responds by preventing voltage differentials from developing and turn- ing the switch on.
