74LVC245A Low Voltage CMOS Octal Bus Transceiver (3-State) Advenced Performance

The 74LVC245A 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 1.65 to 3.6 VCC operations and low power and low noise 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.

It has more speed performance at 3.3V than 5V AC/ACT family, combined with a lower power consumption.

All inputs are equipped with protection circuits against static discharge, giving them 2KV ESD immunity and transient excess voltage.

All floating bus terminals during High Z State must be held HIGH or LOW
