74LCX245 Datasheet (ST Microelectronics) - LOW VOLTAGE CMOS OCTAL BUS TRANSCEIVER

74LCX245, LOW VOLTAGE CMOS OCTAL BUS TRANSCEIVER

The 74LCX245 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 high speed 3.3V applications; it can be interfaced to 5V signal environment for both inputs and outputs.
