... CR timer BA225 / BA225F / BA235 / BA226 / BA226F / BA236 The BA225, BA225F, BA235, BA226, BA226F, and BA236 are monolithic ICs having independent monostable multi- vibrator circuits which consume very low current (0.75mA typ.). Using external resistors and capacitors, the timing control time can be set within a range from 0.01ms to 100ms. ...

... Timing resistor (Pins 2 and 6) Connected to the power supply line, these resistors determine the one-shot period. The timing capacitor is charged through this resistor. The recommended range for the timing resistor is 10k BA225 / BA225F / BA235 / BA226 / BA226F / BA236 1.020 1.015 1.010 1.005 1 ...

... HIGH to LOW. At the same time, the timing capacitor is discharged to be ready for the next operation. 4 BA225 / BA225F / BA235 / BA226 / BA226F / BA236 The voltage, which is determined by comparison of dis- charge resistance and the timing resistance in the IC, remains on the CR pins. If timing resistance is set less, this voltage will reach threshold level (0 ...
