904 00000188 BA226 (Dual CR Timer IC) (8-Pin DIL Package) BA226 CR timer

The BA225, BA225F, BA235, BA226, BA226F, and BA236 are monolithic ICs having independent mono and multi 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 0.01 ms to 100ms.
As the BA225, BA225F, and BA235 are triggered at the rising edge of the signal, they have no trigger input differentiating 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.

* Applications
- Delay timers
- Mono / multi timing controllers (ideal for VTR system controllers)
- Pulse generators

* Features
1) As these are edge trigger types (BA225/ BA235 : rising edge trigger types,
   BA226/BA236 : tailing edge trigger types), there is no need for an input differentiating circuit.
2) The dual type design enables delay timer configuration.
3) Fewer attachments are required.
4) Current consumption is as low as O.75mA for each circuit.
5) Uniformity in the circuit 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 layouts are symmetrical, allowing reverse insertion.
8) Hysteresis in the input results in a high level of noise withstand resistance. 0.49
