74LVX4245 8-Bit Dual Supply Translating Transceiver with TRI-STATE Outputs
October 1995
74LVX4245
8-Bit Dual Supply Translating Transceiver
with TRI-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 Re-
ceive (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 Z 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鈥檚 and 5V LCD dis-
plays
