Over-Voltage Tolerant 1.5V, 1:4
Fanout Buffer
830154I-08
Data Sheet
General Description
The 830154I-08 is an LVCMOS, over-voltage 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 over-voltage 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 830154I-08
ideal for those applications demanding well defined performance and
repeatability. The 830154I-08 is packaged in a small 8-TSSOP and
in an 8-SOIC package.
Features
• Low-skew 1:4 fanout buffer
• Supports 3.3V, 2.5V, 1.8V and 1.5V power supplies
• LVCMOS input and output levels
• 3.6V Over-voltage tolerance at the clock and control inputs
• Supports clock frequencies up to 160MHz
• LVCMOS compatible control input for output disable
• Output disabled to a high-impedance state
• -40°C to 85°C ambient operating temperature
• Available in lead-free RoHS 6 packages (8-TSSOP, 8-SOIC)

NOTE: Electrical parameters are guaranteed over the specified ambient operating temperature range, which is established when device is
mounted in a test socket with maintained transverse airflow greater than 500 lfpm. Device will meet specifications after thermal equilibrium has
been reached under these conditions.
NOTE: Characterized up to FOUT 150MHz.
NOTE 1: Measured from the VDD/2 of the input to VDD/2 of the output.
NOTE 2: This parameter is defined in accordance with JEDEC Standard 65.
NOTE 3: Defined as skew between outputs at the same supply voltage and with equal load conditions. Measured at VDD/2.
NOTE 4: Defined as skew between outputs on different devices operating at the same supply voltage, same temperature, same frequency and
with equal load conditions. Using the same type of inputs on each device, the outputs are measured at VDD/2.
