IDT2305NZ
FIVE OUTPUT
3.3V CLOCK BUFFER
FEATURES:
DESCRIPTION:
• One input to five output buffer/driver
• Low power consumption for mobile applications: less than
32mA at 66.6MHz with unloaded outputs
• 8.7ns max input-output delay
• Buffers all frequencies from DC to 133.33MHz
• Output-output skew < 250ps
• 3.3V operation
• High drive capability
• Available in SOIC package
The IDT2305NZ is a low-cost buffer designed to distribute high-speed
clocks in mobile PC systems and desktop PC systems. The IDT2305NZ
operates at 3.3V with five outputs that can run up to 133.33MHz
The IDT2305NZ is an 8-pin version of the IDT2309NZ. It is designed
for low EMI and power optimization and consumes less than 32mA at
66.6MHz, making it ideal for the low power requirements of mobile systems.

NOTES:
1. Stresses greater than those listed under ABSOLUTE MAXIMUM RATINGS may cause
permanent damage to the device. This is a stress rating only and functional operation
of the device at these or any other conditions above those indicated in the operational
sections of this specification is not implied. Exposure to absolute maximum rating
conditions for extended periods may affect reliability.
2. The input and output negative-voltage ratings may be exceeded if the input and output
clamp-current ratings are observed.
3. The maximum package power dissipation is calculated using a junction temperature
of 150°C and a board trace length of 750 mils.
