74LVX4245
8-Bit Dual Supply Translating Transceiver
with 3-STATE Outputs
General Description
The LVX4245 is a dual-supply, 8-bit translating transceiver
that is designed to interface between a 5V bus and a 3V
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 5V bus; the B Port
interfaces with the 3V bus.
The LVX4245 is suitable for mixed voltage applications
such as laptop computers using 3.3V CPU’s and 5V LCD
displays.
Features
s Bidirectional interface between 5V and 3V buses
s Control inputs compatible with TTL level
s 5V data flow at A Port and 3V data flow at B Port
s Outputs source/sink 24 mA at 5V bus; 12 mA at 3V bus
s Guaranteed simultaneous switching noise level and
dynamic threshold performance
s Implements patented EMI reduction circuitry
s Functionally compatible with the 74 series 245
