The NB3U1548C is an LVCMOS, overvoltage tolerant clock fanout buffer targeted for clock generation in high performance telecommunication, networking and computing applications. The device is optimized for low skew clock distribution in low voltage applications. The input overvoltage tolerance enables using this device in mixed mode voltage applications. An output enable pin controls whether the outputs are in the active or high impedance state. Guaranteed output skew characteristics make the NB3U1548C ideal for those applications demanding well defined performance and repeatability. The NB3U1548C is packaged in a small SOIC−8 and in an TSSOP−8 package.
