74LVX3245
8-Bit Dual Supply Translating Transceiver with
3-STATE Outputs
General Description
The LVX3245 is a dual-supply, 8-bit translating transceiver
that is designed to interface between a 3V bus and a 5V
bus in a mixed 3V/5V supply environment. The Transmit/
Receive (T/R) input determines the direction of data flow.
Transmit (active-HIGH) enables data from A Ports to B
Ports; Receive (active-LOW) enables data from B Ports to
A Ports. The Output Enable input, when HIGH, disables
both A and B Ports by placing them in a high impedance
condition. The A Port interfaces with the 3V bus; the B Port
interfaces with the 5V bus.
The LVX3245 is suitable for mixed voltage applications
such as notebook computers using 3.3V CPU and 5V
peripheral components.
Features
s Bidirectional interface between 3V and 5V buses
s Inputs compatible with TTL level
s 3V data flow at A Port and 5V data flow at B Port
s Outputs source/sink 24 mA
s Guaranteed simultaneous switching noise level and
dynamic threshold performance
s Implements proprietary EMI reduction circuitry
s Functionally compatible with the 74 series 245

Note 1: The “Absolute Maximum Ratings” are those values beyond which
the safety of the device cannot be guaranteed. The device should not be
operated at these limits. The parametric values defined in the Electrical
Characteristics tables are not guaranteed at the absolute maximum ratings.
The “Recommended Operating Conditions” table will define the conditions
for actual device operation.
Note 2: Unused Pins (inputs and I/Os) must be held HIGH or LOW. They
may not float.
