(a) Temperature : 260C (max) Duration : 10 (max) (b) Temperature : 230C (max) Duration : 60 (max) 8 Shock Basically, the 1800 series include height resistance design against shock (guaranteed 3 times drops from 75 cm height on to hard wooden board). In case of unexpected drop, please remeasure the product characteristics. 8 Cleaning Basically, the 1800 series are applicable for ultrasonic cleanings. However, in some cases, during ultrasonic cleanings, damage my occur. Please check conditions carefully beforehand. 8 Others The 1800 series are C-MOS products. And careful handling (same as with C-MOS IC) is needed to avoid electrostatic problems. Incorrect pin connection is cause of trouble. Please make sure to connect correctly as below. #2 terminal GND #4 terminal VDD s Examples for soldering conditions (Infra-red ray reflow soldering) 300 10 s or less 245C Temperature(C) 3.0 (.118) 8.08 (.318) 200 1-5C/s 1-9C/s 100 1-9C/s 60s 0 200s CRYSTAL CLOCK OSCILLATORS Time s PLL cascade connection Crystal units of this series output required frequencies by the PLL (Phase Locked Loop) circuit using quartz oscillation as a reference. Therefore, jitters may increase when the output of this oscillator is connected to a PLL in cascade where the oscillator is operated using an existing PLL circuit in the customer's system as a reference. Check your system carefully before applying to image processing, synchronous process of communication, etc. s Output state during standby Because the output of the clock oscillators of the 1800 series is pulled down to GND (weak pull-down) with a high impedance (typically 500 k) during standby, the pull-down resistor for the input section of GATE IC of the next stage is not necessary. When pulling up the input section of the GATE IC of the next stage, a resistor of 10 k to 50 k or less should be used.

For small orders, or for samples, the packaging form is different according to the requested quantity. 85 |
