54LVX3245
8-Bit Dual Supply Translating Transceiver with
TRI-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 Out-
put Enable input, when HIGH, disables both A and B ports by
placing them in a TRI-STATE 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 systems using 3.3V memories which must interface with
existing busses or other components operating at 5.0V.
