Level Translator Architecture
bi−directional voltage level shifting to transfer data in
multiple supply voltage systems. This device has two
supply voltages, V
the input and output sides of the translator. When used to
transfer data from the V

with a logic level matched to V
V
compatible to V
that independently determine the direction of the data flow
without requiring a directional pin. The one−shot circuits
are used to detect the rising or falling input signals. In
addition, the one shots decrease the rise and fall time of the
output signal for high−to−low and low−to−high transitions.
The magnitude of the pullup resistors can be reduced by
connecting external resistors in parallel to the internal
10 kW resistors.
Input Driver Requirements
drain outputs depend on the magnitude of the pull−up
resistors. In addition, the propagation times (t

of the device that is connected to the translator. The timing
parameters listed in the data sheet assume that the output
impedance of the drivers connected to the translator is less
than 50 kW.

to a low logic level minimizes the power consumption of
the device and drives the I/O V
impedance state. Normal translation operation occurs
when the EN pin is equal to a logic high signal. The EN pin
is referenced to the V

operation of the translator cannot be guaranteed during
single supply operation.
capacitors should be used on the V
pins. Ceramic capacitors are a good design choice to filter
and bypass any noise signals on the voltage lines to the
ground plane of the PCB. The noise immunity will be
maximized by placing the capacitors as close as possible to
the supply and ground pins, along with minimizing the
PCB connection traces.
