Fairchild
Fairchild Semiconductor
Description : 4-Bit BUS SWITCH WITH −2V UNDERSHOOT PROTECTION

General Description
The Fairchild SWITCH FSTU3125 provides four high-speed CMOS TTL-compatible BUS SWITCHes. The low On Resistance of the SWITCH allows inputs to be connected to outputs WITHout adding propagation delay or generating additional ground bounce noise. The A and B Ports are protected against UNDERSHOOT to support an extended range to 2.0V below ground. Fairchild’s integrated Unders hoot Hardened Circuit (UHC) senses UNDERSHOOT at the I/O and responds by preventing voltage differentials from developing and turning the SWITCH on.

Features
UNDERSHOOT hardened to −2V (A and B Ports)
■ 4Ω SWITCH connection between two ports
■ Minimal propagation delay through the SWITCH
■ Low lCC
■ Zero bounce in flow-through mode
■ Control inputs compatible WITH TTL level
■ See application notes AN-5008 and AN-5021 for details on UNDERSHOOT
