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 V
CC
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 V
CC
range from 3.0 V to 3.6 V.
This device is fully specified for partial power-down applications using I
OFF
.
