1 / 7 page © 2003 Fairchild Semiconductor Corporation DS011620 www.fairchildsemi.com July 1993 Revised September 2003 74LVX3245 8-Bit Dual Supply Translating Transceiver with 3-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 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 3V bus; the B Port 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. Features s Bidirectional interface between 3V and 5V buses s Inputs compatible with TTL level s 3V data flow at A Port and 5V data flow at B Port s Outputs source/sink 24 mA s Guaranteed simultaneous switching noise level and dynamic threshold performance s Implements proprietary EMI reduction circuitry s Functionally compatible with the 74 series 245 Ordering Code: Devices also available in Tape and Reel. Specify by appending suffix letter “X” to the ordering code.
