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.
Applications
Delay timers
Monostable multivibrator (ideal for VCR system con-
trollers)
Pulse generators
Features are edge trigger types (BA225 / BA235: ris-
1) As these
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.
