Dual Supply Octal
Translating Transceiver
with 3State Outputs
The 74LVX4245 is a 24pin dualsupply, octal translating
transceiver that is designed to interface between a 5.0 V bus and a 3.0 V
bus in a mixed 3.0 V / 5.0 V supply environment such as laptop
computers using a 3.3 V CPU and 5.0 V LCD display. The A port
interfaces with the 5V bus; the B port interfaces with the 3.0 V bus.
The Transmit/Receive (T/R) input determines the direction of data
flow. Transmit (activeHigh) enables data from the A port to the B
port. Receive (activeLow) enables data from the B port to the A port.
The Output Enable (OE) input, when High, disables both A and B
ports by placing them in 3State.
Features
Bidirectional Interface Between 5.0 V and 3.0 V Buses
Control Inputs Compatible with TTL Level
5.0 V Data Flow at A Port and 3.0 V Data Flow at B Port
Outputs Source/Sink 24 mA at 5.0 V Bus and 12 mA at 3.0 V Bus
Guaranteed Simultaneous Switching Noise Level and Dynamic
Threshold Performance
Available in SOIC and TSSOP Packages
Functionally Compatible with the 74 Series 245
These Devices are PbFree and are RoHS Compliant
