NB3U1548C: 3.3V/2.5V/1.8V/1.5V 160 MHz 1:4 LVCMOS/LVTTL Low Skew Over Voltage Tolerant Fanout Buffer
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.
