The device also precharges the B port to a user-selectable bias voltage BIASV to minimize live-insertion noise. The CBTLV16800 is organized as dual 10-bit bus switches with two different output-enable OE control inputs. When OE is low, the corresponding 10-bit bus switch is on and port A is connected to port B. When OE is high, the switch is open, and a high impedance state exists between the two ports, and port B is precharged to BIASV through the equivalent of a 10-kΩ resistor. 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.

LOW-VOLTAGE 20-BIT BUS SWITCH WITH PRECHARGED OUTPUTS

INDUSTRIAL TEMPERATURE RANGE

IDT74CBTLV16800

FEATURES:
• 5Ω 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 and TVSOP packages

APPLICATIONS:
• 3.3V High Speed Bus Switching and Bus Isolation

DESCRIPTION:

The CBTLV16800 provides 20-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 also precharges the B port to a user-selectable bias voltage BIASV to minimize live-insertion noise.

The CBTLV16800 is organized as dual 10-bit bus switches with two different output-enable OE control inputs. When OE is low, the corresponding 10-bit bus switch is on and port A is connected to port B. When OE is high, the switch is open, and a high impedance state exists between the two ports, and port B is precharged to BIASV through the equivalent of a 10-kΩ resistor.

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.
