74CBTLV16211 LOW-VOLTAGE 24-BIT BUS SWITCH INDUSTRIAL TEMPERATURE RANGE 74CBTLV16211 LOW-VOLTAGE 24-BIT BUS SWITCH FEATURES: DESCRIPTION: 5 A/B bi-directional switch The CBTLV16211 operates as a single 24-bit bus switch or as a dual Isolation Under Power-Off Conditions 12-bit bus switch, which provides high speed switching. This device has Over-voltage tolerant very low ON resistance, resulting in under 250ps propagation delay Latch-up performance exceeds 100mA throughout the switch. When Output Enable (OE) is low, the corresponding VCC = 2.3V - 3.6V, normal range 12-bit bus switch is on and port A is connected to Port B. When OE is high, ESD >2000V per MIL-STD-883, Method 3015 >200V using the switch is off and a high impedance exists between Port A and Port B. machine model (C = 200pF, R = 0) To ensure the high-impedance state during power up or power down, Available in TSSOP package OE should be tied to VCC through a pullup resistor.
