74CBTLV16212 LOW-VOLTAGE 24-BIT BUS EXCHANGE SWITCH INDUSTRIAL TEMPERATURE RANGE LOW-VOLTAGE 24-BIT 74CBTLV16212 BUS EXCHANGE SWITCH FEATURES: DESCRIPTION: 5 A/B bi-directional switch The CBTLV16212 provides a set of 24 high-speed switches for bus Isolation Under Power-Off Conditions exchanging and switching. The device has low ON resistance, resulting Over-voltage tolerant in under 250ps propagation delay through the switch. The CBTLV16212 Latch-up performance exceeds 100mA operates as a single 24-bit bus switch or as a 12-bit bus exchanger, which VCC = 2.3V - 3.6V, normal range provides data exchanging between the four signal ports through the data ESD >2000V per MIL-STD-883, Method 3015 >200V using select (S0-S2) pins. machine model (C = 200pF, R = 0) The CBTLV16212 has the break-before-make feature, which allows Available in TSSOP package zero current when switching between ports B1 and B2.
