IDT74CBTLV3862 LOW-VOLTAGE 10-BIT BUS SWITCH WITH ACTIVE HIGH AND LOW ENABLES LOW-VOLTAGE 10-BIT BUS SWITCH WITH ACTIVE HIGH AND LOW ENABLES INDUSTRIAL TEMPERATURE RANGE IDT74CBTLV3862 FEATURES: DESCRIPTION: • • • • • • The CBTLV3862 provides ten bits of high-speed bus switching with low on-state resistance of the switch allowing connections to be made with minimal propagation delay. The device is organized as one 10-bit bus switch. The switches are controlled by independent active-low enable (OE) and active-high enable (OE) controls. To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver, and OE should be tied to GND. 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, QSOP, and TSSOP packages APPLICATIONS: • 3.3V High Speed Bus Switching and Bus Isolation FUNCTIONAL BLOCK DIAGRAM A1 A10 OE OE 2 11 SW SW SIMPLIFIED SCHEMATIC, EACH SWITCH 22 13 B1 A B B10 1 23 OE OE The IDT logo is a registered trademark of Integrated Device Technology, Inc.

Typical Values are at VCC = 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.
