CD74HCT540EG4 is a hex buffer / line driver with three-state outputs capable of bus-oriented applications. The device enables data transmission between circuits and ensures that data is transferred correctly even at high frequency. This product is made with .54 micron CMOS technology and features high drive outputs and high noise immunity.

The CD74HCT540EG4 is packaged in 20-pin DIP plastic for better thermal performance and offers improved electrical properties. The parts are available in a -55degreeC to 125degreeC operational temperature range. This device is environmentally friendly and provided RoHS compliant versions with Green package type.

Apart from the above features, the reliability of the CD74HCT540EG4 is high. The device has a minimum 1000 hours life test at 125°C and is tested with monotonic testing. In addition, all parts are constructed with back-bias technology that allows the device to remain on 2V without permanent damage. This technology results in improved signal integrity, higher manufacturing yield rates, longer product lifetime, and improved signal-to-noise ratio.

The CD74HCT540EG4 is most suitable for conversion or buffering of TTL logic levels to or from the family of Logic Interface Bus (I2C). It works by blocking the paths between the TTL and the I2C level shifting device and allows transmission of digital signals in both directions by controlling enable inputs. The buffers also enable data transfer up to 1MHz when used in the bi-directional 3-State mode.

The CD74HCT540EG4 is ideal for applications that require low-capacitance connection between TTL and I2Clevel devices. It is also suitable for applications that need power-efficiency and good stability. The CD74HCT540EG4 is used in audio systems, digital telephones, security systems, remote access terminals and video systems.
