1 / 6 page 1 Standard ICs 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. As the BA225, BA225F, and BA235 are triggered at the rising edge of the signal, they have no trigger input differenti- ating circuit and can be used in measuring instruments, control devices, digital data systems and other equipment as sub-compact attachments. The BA226, BA226F, and BA236 are available as falling edge trigger types. •Block diagram OUT1 CR1 TRIGGER1 4 GND 3 2 1 5 6 7 8 VCC OUT2 CR2 TRIGGER2 O T CR O T CR 1 OT CR VCC VCC GND 2 3 4 5 6 7 8 9 O T CR BA225 / BA225F BA226 / BA226F BA235 / BA236 •Applications Delay timers Monostable multivibrator (ideal for VCR system con- trollers) Pulse generators •Features 1) As these are edge trigger types (BA225 / BA235: ris- ing edge trigger types, BA226 / BA236: falling edge trigger types), there is no need for an input differenti- ating circuit. 2) The dual type design enables delay timer configura- tion. 3) Fewer attachments are required. 4) Current dissipation is as low as 0.75mA for each cir- cuit. 5) Uniformity in the supply current between high and low output states simplifies the design of the power supply section. 6) Wide operating power supply voltage range of 4.0V to 16V. 7) The BA235 and BA236 pin assignments are sym- metrical, allowing reverse insertion. 8) Hysteresis in the input results in a high level of noise withstand resistance. |
