1. General description
The 74CBTLVD3861 is a 10-bit 3.3 V to 1.8 V level translating bus switch with one output enable
(OE) input. When OE is LOW, the switch is closed and port A is connected to the B port. When OE
is HIGH, the switch is disabled.
To ensure the high-impedance OFF-state during power-up or power-down, OE should be tied
to the VCC through a pull-up resistor. The minimum value of the resistor is determined by the
current-sinking capability of the driver.
Schmitt trigger action at control input makes the circuit tolerant to slower input rise and fall times
across the entire VCC range from 3.0 V to 3.6 V.
This device is fully specified for partial power-down applications using IOFF.
