3 / 7 page 2014/10/29 ( 3 / 7 ) NJU6229 Series Preliminary ■TERMINAL DESCRIPTION SYMBOL FUNCTION CONT 3-state Output Buffer Control Terminal CONT FOUT H or OPEN Output of f0 L High-Z XTI Quartz Crystal Connecting Terminals XTO VSS GND Terminal (Vss=0V) FOUT Frequency Output VDD VDD=1.62 to 5.50V ■FUNCTIONAL DESCRIPTION ●Output Disable Function When CONT Terminal goes “Low”, the F OUT Terminal output becomes High impedance. CONT FOUT Oscillator High(Open) Frequency output Normal operation Low Hi-Z Normal operation ●Variable Pull-up Resistance The CONT Terminal pull-up resistance changes in response to the input level. When CONT is tied “LOW” level, the pull-up resistance is large, reducing the current consumed by the resistance. When CONT is left open circuit, the pull-up resistance is small, which increases the input susceptibility to external noise. However, the pull-up resistance ties the CONT Terminal “High” level to prevent external noise from unexpectedly stopping the output. ■ABSOLUTE MAXIMUM RATINGS (VSS=0V, Ta=25C) PARAMETER SYMBOL RATING UNIT Supply Voltage VDD -0.5 to +6.0 V Input Voltage VIN VSS-0.5∼VDD+0.5 V Output Voltage VO -0.5 to VDD+0.5 V Input Current IIN 10 mA Output Current IO 25 mA Operating Temperature Range Topr -40 to +85 C Storage Temperature Range Tstg -55 to +150 C Note1) If the supply voltage(VDD) is less than 6.0V, the input voltage must not over the VDD level though 6.0V is limit specified Note2) Decupling capacitor should be connected between VDD and VSS due to the stabilized operation for the circuit. |
