IDT74CBTLV16214 LOW-VOLTAGE 12-BIT 3:1 MUX / DEMUX BUS SWITCH INDUSTRIAL TEMPERATURE RANGE LOW-VOLTAGE 12-BIT 3:1 MUX / DEMUX BUS SWITCH FEATURES: IDT74CBTLV16214 DESCRIPTION: 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 SSOP, TSSOP, and TVSOP packages • • • • • • The CBTLV16214 provides a set of 12 high-speed buses switching between three separate ports. The low ON resistance allows inputs to be connected to outputs without adding propagation delay. The CBTLV16214 operates as a 12-bit bus select through the data select (S0-S2) terminals. APPLICATIONS: • Muxing and demuxing • 3.3V High Speed Bus Switching and Bus Isolation • Hot-swapping, hot-docking FUNCTIONAL BLOCK DIAGRAM 1A 2 SIMPLIFIED SCHEMATIC, EACH SWITCH 54 SW 53 SW SW 3 1B1 1B2 1B3 A 12A 27 30 SW 29 SW SW 28 B 12B1 12B2 12B3 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.
