BA225 - CR timer

Rohm 2009/03/23 09:35
Description
The BA225, BA225F, BA235, BA226, BA226F, and BA236 are monolithic ICs having independent monostable multivibrator 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 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.

Features
*As these are edge trigger types (BA225 / BA235: rising edge trigger types, BA226 / BA236: falling edge trigger types), there is no need for an input differentiating circuit.
*The dual type design enables delay timer configuration.
*Fewer attachments are required.
*Current dissipation is as low as 0.75mA for each circuit.
*Uniformity in the supply current between high and low output states simplifies the design of the power supply section.
*Wide operating power supply voltage range of 4.0V to 16V.
*The BA235 and BA236 pin assignments are symmetrical, allowing reverse insertion.
*Hysteresis in the input results in a high level of noise withstand resistance.

Applications
*Delay timers
*Monostable multivibrator (ideal for VCR system controllers)
*Pulse generators

Using its expertise in LSI technology, ROHM has developed new high density driver chips for use in the KD3002-DF10A .
Capable of being employed for both thermal and thermal transfer printing, with a print speed of 200mm/s, the resulting print heads are the fastest in their class. The high-speed and high-density printing answers the needs of ATM, kiosk and ticket printing devices, which are increasingly being called upon to produce graphical output.

* Applications
Label printers
Ticket printers
Terminal printers

* Features
1) The use of a special partial glaze and the latest heating element structure, along with new high-density driver chips that can accept big current, has allowed ROHM to achieve print speeds of 200mm/s with using thermal history control, the fastest in its class.
2) One rank resistance value of 1000Ω ± 3% eliminates the inconvenience of rank selection.
3) The required driving voltage of 3.15 to 5.25V allows wide range of power supply voltage setting. This also allows multiple choice of electronic components for printers.
4) 2-inch, 3-inch, 4-inch and 8-inch series are available.

The BR93LC46-W series are CMOS serial input / output-type memory circuits (EEPROMs) that can be programmed electrically. Each is configured of 64 words × 16 bits (1,024 bits), and each word can be accessed individually and data read from it and written to it. Operation control is performed using five types of commands. The commands, addresses, and data are input through the DI pin under the control of the CS and SK pins. In a write operation, the internal status signal (READY or BUSY) can be output from the DO pin.

Description
The BH1417F is a FM stereo transmitter IC that transmits simple configuration. The IC consists of a stereo modulator for generating stereo composite signals and a FM transmitter for broadcasting a FM signal on the air. The stereo modulator generates a composite signal which consists of the MAIN, SUB, and pilot signal from a 38kHz oscillator. The FM transmitter radiates FM wave on the air by modulating the carrier signal with a composite signal. Frequency is set for North America.

Features
1) It is possible to improve the timbre because it has the pre-emphasis circuit, limiter circuit, and the low-pass filter circuit.
2) Built-in pilot-tone system FM stereo modulator circuit.
3) The transmission frequency is stable because it has a PLL system FM transmitter circuit.
4) PLL controls data input in parallel (4bits, 14ch for North America).
