IDT74CBTLV3125 LOW-VOLTAGE QUADRUPLE BUS SWITCH
INDUSTRIAL TEMPERATURE RANGE
LOW-VOLTAGE QUADRUPLE BUS SWITCH
IDT74CBTLV3125
FEATURES:
- - - - - - - - - Pin-Out Compatible with Standard `125 Logic Products 5 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) Output Enable, Active Low Available in TSSOP and QSOP packages
DESCRIPTION:
The CBTLV3125 features four independent switches. Each switch is enabled when the associated output-enable (OE) input is low. 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.
APPLICATIONS:
- 3.3V High Speed Bus Switching and Bus Isolation

NOTE: 1. Stresses greater than those listed under ABSOLUTE MAXIMUM RATINGS may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect reliability.

NOTES: 1. Typical values are at VCC = 3.3V, +25C 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.

NOTE: 1. The propagation time is the calculated RC time constant of the typical on-state resistance of the switch and the specified load capacitance when driven by an ideal voltage source (zero output impedance).
