16-Bit to 32-Bit Multiplexer/Demultiplexer Bus Switch with -2V Undershoot Protection
FSTU32160A 16-Bit to 32-Bit Multiplexer/Demultiplexer Bus Switch with −2V Undershoot Protection June 1999 Revised December 2000 FSTU32160A 16-Bit to 32-Bit Multiplexer/Demultiplexer Bus Switch with −2V Undershoot Protection General Description Features The Fairchild Switch FSTU32160A is a 16-bit to 32-bitUndershoot hardened to −2V (A and B Ports). high-speed CMOS TTL-compatible multiplexer/demulti-4Ω switch connection between two ports. plexer bus switch. The low on resistance of the switch Minimal propagation delay through the switch. allows inputs to be connected to outputs without adding Low l . propagation delay or generating additional ground bounce CC noise.Zero bounce in flow-through mode. The device can be used in applications where two busesControl inputs compatible with TTL level. need to be addressed simultaneously. The FSTU32160A is See Applications Note AN-5008 for details designed so that the A Port demultiplexes into B or B or 1 2 both. The A and B Ports have “undershoot hardened” cir- cuit protection to support an extended range to 2.0V below ground. Fairchild’s integrated Undershoot Hardened Cir- cuit, UHC senses undershoot at the I/O’s, and responds by preventing voltage differentials from developing and turning on the switch. Two select (S , S ) inputs provide switch enable control. 1 2 When S , S are HIGH, the device precharges the B Port 1 2 to a selectable bias voltage (Bias V) to minimize live inser- tion noise.
