XC2301 Series ETR1409_001 Tri-State Buffer ICs ■GENERAL DESCRIPTION The 2301 series are a group of high frequency, CMOS low power tri-state buffer ICs with input amplifier, divider and output tri-state buffer circuits built-in. Output can be selected from any one of the following values for fin (input frequency) : fin/1, fin/2, fin/4, fin/8. The series is available in an ultra small SOT-26 package. ■APPLICATIONS ■FEATURES ●VCXO Modules Maximum Operating Frequency : 160MHz ●Crystal Oscillator Modules Operating Voltage Range : 3.3V±10% Divider Ratio : Selectable from fin/1, fin/2, fin/4, fin/8 Output : 3-State CMOS Low Power Consumption Built-In Input Amplifier Ultra Small Package ■PIN CONFIGURATION : SOT-26 ■PIN ASSIGNMENT PIN NUMBER 1 2 3 4 5 PIN NAME /INH XT VSS Q0 VDD 6 /XT FUNCTION Stand-by Control (*) Clock Input GND Clock Output Power Supply Feedback Resistor Connection (Output) *Stand-by control pin has a pull-up resistor built-in. ■/INH, Q0 PIN FUNCTION /INH Q0 “H” or OPEN Clock Output “L” High Impedance 1/6 XC2301 Series ■ PRODUCT CLASSIFICATION ●Ordering Information XC2301 ①②③④⑤⑥ DESIGNATOR DESCRIPTION SYMBOL ① Duty Level C : CMOS (VDD/2) ② Fixed Number 5 :- 1 : Q0=fin/1 2 : Q0=fin/2 4 : Q0=fin/4 8 : Q0=fin/8 Divider Ratio ③ DESCRIPTION ④ Output V : Tri-state buffer ⑤ Package M : SOT-26 ⑥ Device Orientation R : Embossed tape, standard feed L : Embossed tape, reverse feed ■BLOCK DIAGRAM ■ABSOLUTE MAXIMUM RATINGS PARAMETER SYMBOL CONDITIONS Ta=25℃ UNITS Supply Voltage VDD VSS - 0.3 ~ VSS + 7.0 V Input Voltage VIN VSS - 0.3 ~ VDD + 0.3 V Power Dissipation Pd 250(**) mW Operating Temperature Range Topr - 40 ~ + 85 ℃ Storage Temperature Range Tstg - 55 ~ + 125 ℃ ** When implemented on a glass epoxy PCB. ■ELECTRICAL CHARACTERISTICS ●DC Electrical Characteristics (Unless otherwise stated, VDD=3.3V, No Load, Ta=25℃) PARAMETER SYMBOL Operating Supply Voltage VDD Input Voltage "High" VIH Input Voltage "Low" VIL Output Voltage "High" VOH Output Voltage "Low" VOL CONDITIONS MIN.
