2SK2938-Silicon N Channel MOS FET High Speed Power Switching

Description
 The HD61203U is a common signal driver for dot matrix liquid crystal graphic display systems.
It generates the timing signals (switch signal to convert LCD waveform to AC, frame synchronous signal) and supplies them to the column driver to control display.
It provides 64 driver output lines and the impedance is low enough to drive a large screen.
As the HD61203U is produced by a CMOS process, it is fit for use in portable battery-driven equipment utilizing the liquid crystal display’s low power consumption.
The user can easily construct a dot matrix liquid crystal graphic display system by combining the HD61203U and the column (segment) driver HD61202U.

Features

HD61203U - Dot Matrix Liquid Crystal Graphic Display 64-Channel Common Driver

Description
 The HD74LV1GT126A has a bus buffer gate with 3–state output in a 5 pin package.
Output is disabled when the associated output enable (OE) input is low.
To ensure the high impedance state during power up or power down, OE should be connected to VCC through a pull-down resistor; the minimum value of the resistor is determined by the current souring capability of the driver.
Low voltage and high speed operation is suitable for the battery powered products (e.g., notebook computers), and the low power consumption extends the battery life.

Features
* The basic gate function is lined up as hitachi uni logic series.
* Supplied on emboss taping for high speed automatic mounting.
* TTL compatible input level.
- Supply voltage range : 4.5 to 5.5 V
- Operating temperature range : –40 to +85°C
* All inputs VIH (Max.) = 5.5 V (@VCC = 0 V to 5.5 V)
- All outputs VO (Max.) = 5.5 V (@VCC = 0 V)
* Output current ±12 mA (@VCC = 4.5 V to 5.5 V)
* All the logical input has hysteresis voltage for the slow transition.

 

HD74LV1GT126A - Bus Buffer Gate with 3–state Output

Description
 The HA16148PS is an IC with a high-voltage power MOS FET and current-mode type PWM controller mounted in a DILP-8 (DP-8) standard package, suitable for low-power power supplies in the 10 W class and below.
 The HA16148PS includes an energy-saving mode for holding down power consumption when on standby (no load). When the energy-saving mode is entered, the operating frequency is reduced to 1/4 the normal frequency, reducing power consumption. A starter circuit is also provided on-chip, eliminating the need for the external start-up resistance needed with previous controller ICs. The starter circuit in this IC is turned off automatically after the IC starts up, enabling the start-up resistance power consumption to be decreased.

 The HA16148PS includes a soft start circuit, OVP circuit, and remote on/off circuit, making it possible to configure a simple protection circuit with fewer external parts than previously. Also provided are a current sense resistance and a leading edge blanking circuit that masks spike noise on current sense input, making noise reduction in a power supply set comparatively easy.
 The HA16148PS is equipped with an error amp circuit inverting input (FB) pin and output (COMP) pin, enabling special-purpose design for both flyback system secondary-side output voltage detection and primary-side back-up transformer output voltage detection types.

Features
·  Built-in high-voltage power MOS FET
·  Energy-saving mode (power saving through reduction of operating frequency to 1/4 normal frequency when on standby)
·  Built-in starter circuit, reducing power loss of start-up resistance when on standby (external start-up resistance not necessary)
·  Built-in soft start circuit, eliminating need for external connection
·  Remote on/off function, enabling power saving by halting PWM output without turning off power supply
·  Built-in current sense resistance and leading edge blanking circuit, for sense-resistance-less and noisecancellation- filter-less implementation
·  Built-in over voltage protection circuit
·  Built-in over temperature protection circuit

Description
 This multivibrator features both a negative, A, and a positive, B, transition triggered input, either of which can be used as an inhibit input. Also included is a clear input that when taken low resets the one shot. The HD74HC123A can be triggered on the positive transition of the clear while A is held low and B is held high.
 The HD74HC123A is retriggerable. That is it may be triggered repeatedly while their outputs are
generating a pulse and the pulse will be extended. Pulse width stability over a wide range of temperature. The output pulse equation is simply: tw = (Rext) (Cext).

Features
·  High Speed Operation
·  High Output Current: Fanout of 10 LSTTL Loads
·  Wide Operating Voltage: VCC = 2 to 6 V
·  Low Input Current: 1 µA max
·  Low Quiescent Supply Current
