Over-Voltage Tolerant 1.5V, 1:4 830154I-08 Fanout Buffer Data Sheet General Description Features Low-skew 1:4 fanout buffer The 830154I-08 is an LVCMOS, over-voltage tolerant clock fanout buffer targeted for clock generation in high-performance Supports 3.3V, 2.5V, 1.8V and 1.5V power supplies telecommunication, networking and computing applications. The LVCMOS input and output levels device is optimized for low-skew clock distribution in low-voltage 3.6V Over-voltage tolerance at the clock and control inputs applications. The input over-voltage tolerance enables using this Supports clock frequencies up to 160MHz device in mixed-mode voltage applications. An output enable pin LVCMOS compatible control input for output disable controls whether the outputs are in the active or high impedance Output disabled to a high-impedance state state. Guaranteed output skew characteristics make the 830154I-08 -40C to 85C ambient operating temperature ideal for those applications demanding well defined performance and Available in lead-free RoHS 6 packages (8-TSSOP, 8-SOIC) repeatability. The 830154I-08 is packaged in a small 8-TSSOP and in an 8-SOIC package.
