What this part does on the board
The 2305NZ-1HDCG8 is a single-ended LVCMOS fanout buffer from Renesas. It takes one LVCMOS clock input and distributes it to five LVCMOS outputs, buffered and re-driven to maintain signal integrity. The maximum output frequency is 133.33 MHz, which sets the upper bound for the clock tree it feeds — anything faster needs a different buffer or a differential pair like LVPECL. The supply voltage range is 3V to 3.6V, so it sits comfortably on a 3.3V rail. The single-circuit design means one buffer per package; if you need multiple independent fanout groups, you'll use several of these or a multi-circuit part.
Temperature grade and where it fits
The operating temperature range is 0°C to 70°C — commercial grade. That puts this part in indoor, temperature-controlled equipment: office networking gear, telecom racks, test instruments, consumer electronics. Not for outdoor base stations, engine bays, or factory floors where ambient can push past 70°C.
Package and mounting
Housed in an 8-SOIC package (3.90 mm body width), surface-mount. The supplier device package is 8-SOIC, so the footprint is standard SOIC-8 — no surprises for the pick-and-place or reflow profile. Shipping options include Tape & Reel and Cut Tape.
Lifecycle and compliance
ROHS3 compliant, so it passes the latest EU restriction directive. No LTB risk for new designs in the near term, but always worth checking the factory lead time at quote — active status doesn't guarantee short lead times.
