FST3306 2-Bit Low Power Bus Switch February 2001 Revised February 2001 FST3306 2-Bit Low Power Bus Switch General Description Features The FST3306 is a 2-bit ultra high-speed CMOS FET busTypical 3Ω switch resistance at 5.0V V CC switch with TTL-compatible active LOW control inputs. The Minimal propagation delay through the switch low on resistance of the switch allows inputs to be con- Power down high impedance input/output nected to outputs with minimal propagation delay and with- Zero bounce in flow through mode. out generating additional ground bounce noise. The device is organized as a 2-bit switch with independent bus enableTTL compatible active LOW control inputs (BE) controls. When BE is LOW, the switch is ON and Control inputs are overvoltage tolerant Port A is connected to Port B. When BE is HIGH, the switch is OPEN and a high-impedance state exists between the two ports. Control inputs tolerate voltages up to 5.5V independent of V .
