74LVX3245 8-Bit Dual Supply Translating Transceiver with 3-STATE Outputs July 1993 Revised September 2003 74LVX3245 8-Bit Dual Supply Translating Transceiver with 3-STATE Outputs General Description Features The LVX3245 is a dual-supply, 8-bit translating transceiverBidirectional interface between 3V and 5V buses that is designed to interface between a 3V bus and a 5VInputs compatible with TTL level bus in a mixed 3V/5V supply environment. The Transmit/ 3V data flow at A Port and 5V data flow at B Port Receive (T/R) input determines the direction of data flow. Outputs source/sink 24 mA Transmit (active-HIGH) enables data from A Ports to B Ports; Receive (active-LOW) enables data from B Ports toGuaranteed simultaneous switching noise level and dynamic threshold performance A Ports. The Output Enable input, when HIGH, disables both A and B Ports by placing them in a high impedanceImplements proprietary EMI reduction circuitry condition. The A Port interfaces with the 3V bus; the B Port Functionally compatible with the 74 series 245 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.
