553MILFT

RENESAS · Clock Buffers, Drivers, Distributors · SOIC-8

553MILFT from RENESAS, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VDD power_in Positive supply. Connect to +2.5 V, +3.3 V, or +5.0 V (recommended 2.375 V to 5.25 V). Decouple to GND (pin 4) with a 0.01 uF capacitor placed as close to the device as possible.
2 Q0 output Clock output 0. CMOS push-pull buffered copy of ICLK with ~20 Ω nominal output impedance. Tri-stated when OE is low. A 33 Ω series terminator is recommended for traces longer than 1 inch.
3 Q1 output Clock output 1. CMOS push-pull buffered copy of ICLK with ~20 Ω nominal output impedance. Tri-stated when OE is low.
4 GND power_in Ground return. Connect to system ground; forms the return path for the VDD decoupling capacitor on pin 1.
5 ICLK input Reference clock input, 5 V tolerant regardless of VDD. Accepts 0 to 200 MHz rail-to-rail input; nominal switching threshold is VDD/2. CIN ~5 pF.
6 Q2 output Clock output 2. CMOS push-pull buffered copy of ICLK with ~20 Ω nominal output impedance. Tri-stated when OE is low.
7 Q3 output Clock output 3. CMOS push-pull buffered copy of ICLK with ~20 Ω nominal output impedance. Tri-stated when OE is low.
8 OE input Output Enable. When low, all four Q outputs are tri-stated; connect to VDD (through a pull-up or directly) for normal buffered operation. CMOS input, VIH = 2 V (at 3.3/5 V) or 1.8 V (at 2.5 V).
