STMicroelectronics 54VCXHR162245
The 54VCXHR162245 is a low voltage CMOS 16bit bus transceiver (3-state) developed with submicron silicon gate and five-layer metal wiring C²MOS technology. It is ideal for low power and very high speed 1.8 to 3.6 V applications; it can be interfaced to 3.6 V signal environment for both inputs and outputs. This IC is intended for twoway asynchronous communication between data buses; the direction of data transmission is determined by DIR input.| Part No. | 54VCXHR162245 |

DESCRIPTION
The two enable inputs nG can be used to disable the device so that the buses are effectively isolated. The device circuits include 26 Ω series resistance in the A and B port outputs. These resistors reduce the line noise in high speed applications. Bus hold on data inputs is provided in order to eliminate the need for the external pull-up or pull-down resistor. All inputs and outputs are equipped with protection circuits against static discharge, giving them 2 kV ESD immunity and transient excess voltage.
