551MLF

RENESAS · Clock Buffers, Drivers · SOIC-8

551MLF from RENESAS, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 ICLK input Clock input with an internal pull-up resistor.
2 Q1 output Non-inverting clock output 1, tri-stated when OE is low.
3 Q2 output Non-inverting clock output 2, tri-stated when OE is low.
4 Q3 output Non-inverting clock output 3, tri-stated when OE is low.
5 Q4 output Non-inverting clock output 4, tri-stated when OE is low.
6 GND power_in Connect to ground; the 0.01 µF decoupling capacitor between VDD (pin 7) and GND should be placed as close to the device as possible.
7 VDD power_in Connect to 3.3 V or 5.0 V (power supply voltage range is +3.0 V to +5.5 V measured with respect to GND).
8 OE input Output Enable input that tri-states the outputs when low, with an internal pull-up resistor.
