DESCRIPTION
With V DD equal to zero volts, the UT54ACS164245S outputs and inputs present a minimum impedance of 1MΩ making it ideal for "cold spare" applications. Balanced outputs and low "on" output impedance make the UT54ACS164245S well suited for driving high capacitance loads and low impedance backplanes. The UT54ACS164245S enables system designers to interface 3.3 volt CMOS compatible components with 5 volt CMOS components. For voltage translation, the A port interfaces with the 3.3 volt bus; the B port interfaces with the 5 volt bus. The direction control (DIRx) controls the direction of data flow.
