DESCRIPTION
The 74LVQ245 is a low voltage CMOS OCTAL BUS TRANSCEIVER (3-STATE fabricated with sub-micron silicon gate and double-layer metal wiring C2MOS technology. It is ideal for low power and low noise 3.3V applications.
This IC is intended for two-way asynchronous communication between data buses and the direction of data transmission is determined by DIR input. The enable input G can be used to disable the device so that the buses are effectively isolated.
All inputs and outputs are equipped with protection circuits against static discharge, giving them 2KV ESD immunity and transient excess voltage.
All floating bus terminals during High Impedance State must be held HIGH or LOW.
