CDC2351MDBREP

Texas Instruments · Clock Buffers, Drivers · SSOP-24-208mil

CDC2351MDBREP from Texas Instruments, in a SSOP-24-208mil. 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 GND power_in Ground reference pin; the datasheet notes distributed VCC and ground pins are used to reduce switching noise.
2 Y10 output Clock output 10 with internal series damping resistor; tri-stated (high impedance) when OE is high, IOH −12 mA and IOL 12 mA max at VCC = 3 V.
3 VCC power_in Supply pin; recommended operating supply voltage is 3 V to 3.6 V (nominal 3.3 V).
4 Y9 output Clock output 9 with internal series damping resistor; tri-stated (high impedance) when OE is high, IOH −12 mA and IOL 12 mA max at VCC = 3 V.
5 OE input Active-low output enable; when high, all outputs Y go to high-impedance state; when low, outputs follow input A. LVTTL-compatible, input voltage range 0 V to 5.5 V.
6 A input Clock input that is distributed to the 10 outputs; LVTTL-compatible, input voltage range 0 V to 5.5 V, input clock frequency up to 100 MHz.
7 P0 input Factory propagation-delay adjustment pin, not intended for customer use; it should be connected to GND.
8 P1 input Factory propagation-delay adjustment pin, not intended for customer use; it should be connected to GND.
9 Y8 output Clock output 8 with internal series damping resistor; tri-stated (high impedance) when OE is high, IOH −12 mA and IOL 12 mA max at VCC = 3 V.
10 VCC power_in Supply pin; recommended operating supply voltage is 3 V to 3.6 V (nominal 3.3 V).
11 Y7 output Clock output 7 with internal series damping resistor; tri-stated (high impedance) when OE is high, IOH −12 mA and IOL 12 mA max at VCC = 3 V.
12 GND power_in Ground reference pin; the datasheet notes distributed VCC and ground pins are used to reduce switching noise.
13 GND power_in Ground reference pin; the datasheet notes distributed VCC and ground pins are used to reduce switching noise.
14 Y6 output Clock output 6 with internal series damping resistor; tri-stated (high impedance) when OE is high, IOH −12 mA and IOL 12 mA max at VCC = 3 V.
15 VCC power_in Supply pin; recommended operating supply voltage is 3 V to 3.6 V (nominal 3.3 V).
16 Y5 output Clock output 5 with internal series damping resistor; tri-stated (high impedance) when OE is high, IOH −12 mA and IOL 12 mA max at VCC = 3 V.
17 GND power_in Ground reference pin; the datasheet notes distributed VCC and ground pins are used to reduce switching noise.
18 Y4 output Clock output 4 with internal series damping resistor; tri-stated (high impedance) when OE is high, IOH −12 mA and IOL 12 mA max at VCC = 3 V.
19 Y3 output Clock output 3 with internal series damping resistor; tri-stated (high impedance) when OE is high, IOH −12 mA and IOL 12 mA max at VCC = 3 V.
20 GND power_in Ground reference pin; the datasheet notes distributed VCC and ground pins are used to reduce switching noise.
21 Y2 output Clock output 2 with internal series damping resistor; tri-stated (high impedance) when OE is high, IOH −12 mA and IOL 12 mA max at VCC = 3 V.
22 VCC power_in Supply pin; recommended operating supply voltage is 3 V to 3.6 V (nominal 3.3 V).
23 Y1 output Clock output 1 with internal series damping resistor; tri-stated (high impedance) when OE is high, IOH −12 mA and IOL 12 mA max at VCC = 3 V.
24 GND power_in Ground reference pin; the datasheet notes distributed VCC and ground pins are used to reduce switching noise.
