8-Bit Dual Supply Translating Transceiver with 3-STATE Outputs

Favorite

Overview

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/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 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's and 5V LCD displays.

  • This product is general usage and suitable for many different applications.
  • Bidirectional interface between 5V and 3V buses
  • Control inputs compatible with TTL level
  • 5V data flow at A Port and 3V data flow at B Port
  • Outputs source/sink 24 mA at 5V bus; 12 mA at 3V bus
  • Guaranteed simultaneous switching noise level and dynamic threshold performance
  • Implements patented EMI reduction circuitry
  • Functionally compatible with the 74 series 245
