DESCRIPTION
The LVX3245 is a dual supply low voltage CMOS OCTAL BUS TRANSCEIVER fabricated with sub-micron silicon gate and double-layer metal wiring C2MOS technology. Designed for use as an interface between a 5V bus and a 3.3V bus in mixed 5V/3.3V supply sistems, it achieves high speed operation while maintaining the CMOS low power dissipation.
This IC is intended for two-way asynchronous communication between data buses; the direction of data trasmission is determined by DIR input. The enable input G can be used to disable the device so that the buses are effectively isolated. The A-port interfaces with the 3V bus, the B-port with the 5V bus.
All inputs and outputs are equipped with protection circuits against static discharge, giving them 2KV ESD immunity and transient excess voltage.

■ HIGH SPEED: tPD = 6 ns (TYP.) at VCC = 3.3V
■ LOW POWER DISSIPATION:
   ICC =8 µA (MAX.) at TA = 25 oC
■ LOW NOISE: VOLP = 0.3V(TYP.) at VCC = 3.3V
■ SYMMETRICAL OUTPUT IMPEDANCE:
   |IOH| = IOL = 4 mA (MIN)
■ BALANCEDPROPAGATIONDELAYS: tPLH ≅ tPHL
