74CBTLV16212 LOW-VOLTAGE 24-BIT BUS EXCHANGE SWITCH INDUSTRIAL TEMPERATURE RANGE LOW-VOLTAGE 24-BIT BUS EXCHANGE SWITCH 74CBTLV16212 DESCRIPTION: FEATURES: 5Ω Ω A/B bi-directional switch Isolation Under Power-Off Conditions Over-voltage tolerant Latch-up performance exceeds 100mA VCC = 2.3V - 3.6V, normal range ESD >2000V per MIL-STD-883, Method 3015; >200V using machine model (C = 200pF, R = 0) • Available in TSSOP package The CBTLV16212 provides a set of 24 high-speed switches for bus exchanging and switching. The device has low ON resistance, resulting in under 250ps propagation delay through the switch. The CBTLV16212 operates as a single 24-bit bus switch or as a 12-bit bus exchanger, which provides data exchanging between the four signal ports through the data select (S0-S2) pins. The CBTLV16212 has the break-before-make feature, which allows zero current when switching between ports B1 and B2. • • • • • • APPLICATIONS: • 3.3V High Speed Bus Switching and Bus Isolation FUNCTIONAL BLOCK DIAGRAM 1A 1 2 SIMPLIFIED SCHEMATIC, EACH SWITCH 54 SW 1B 1 SW SW 1A 2 3 53 SW 1B 2 A 12A1 27 30 SW B 12B1 SW SW 12A2 28 29 SW 12B2 FLOW CONTROL CIRCUITRY S0 S1 S2 1 56 55 The IDT logo is a registered trademark of Integrated Device Technology, Inc.

Typical values are at 3.3V, +25°C ambient. 2. The increase in supply current is attributable to each input that is at the specified voltage level rather than VCC or GND. 3. This is measured by the voltage drop between the A and B terminals at the indicated current through the switch.
