PCK351DB,118

Clock Buffers, Drivers Overview

The PCK351DB,118 is a high-performance 3.3 V LVTTL clock distribution device featuring one input and ten outputs with three-state capability. It operates within a supply voltage range of 3.0 V to 3.6 V and supports an industrial temperature range of −40 °C to +85 °C. The component utilizes distributed VCC and GND pins to minimize switching noise. Key electrical parameters include a propagation delay (tPLH/tPHL) of 2.5 ns to 5.9 ns, output skew time (tsk(o)) up to 0.5 ns, and pulse skew time (tsk(p)) up to 0.8 ns under recommended operating conditions. It provides balanced high-drive outputs with -32 mA IOH and 32 mA IOL capabilities.

Clock Buffers, Drivers Feature Summary

• 1:10 LVTTL clock distribution with low output-to-output skew (max 0.5 ns)
• Overvoltage tolerant inputs and outputs compatible with LVTTL levels
• Balanced high-drive outputs (-32 mA IOH, 32 mA IOL)
• Distributed VCC and ground pins reduce switching noise

Clock Buffers, Drivers Applications

• Clock distribution in systems requiring low skew timing
• Industrial control applications within the specified temperature range
• Digital circuits utilizing LVTTL logic standards

Clock Buffers, Drivers Procurement Notes

Verify the ordering suffix '118' against current manufacturer documentation to confirm specific tape-and-reel packaging or moisture sensitivity level requirements. Ensure the source document matches the requested part number variant before finalizing procurement decisions.

Clock Buffers, Drivers Selection Notes

Select this component for designs requiring a single clock source to drive ten loads with minimal skew. Ensure the system operates between 3.0 V and 3.6 V. Verify that the load capacitance does not exceed 50 pF per output to maintain specified dynamic characteristics. Unused pins must be tied HIGH or LOW.

Clock Buffers, Drivers Part Context

The PCK351DB variant specifically denotes the SSOP24 package (SOT340-1), which is a plastic shrink small outline package with 24 leads and a body width of 5.3 mm. This differs from the SO24 (SOT137-1) version. Both variants share identical electrical specifications and functionality.
