WQ41U in catalogue
An LED driver that will sequentially light ten LEDs when a gradually increasing voltage is applied to pin 5, (dot mode) or in bar mode all LEDs indicating voltages below input are lit. In dot mode there is a slight overlap so that at no point are all LEDs extinguished. A brightness control will set LED current between 2mA and 30mA. The drivers are stackable and displays with 100 or more LEDs are possible. Supply voltage 3V to 18V. The driver that sets the indication points can be referenced to a

FE29G in catalogue
For use when handling CMOS and other devices that are prone to electrostatic damage. This fabric wrist strap is comfortable to wear and prevents electrostatic charge building up. The strap is pulled tightly around the wrist and locked in place with a buckle. Three conductive threads woven into the fabric press against the skin and allow any electrostatic charge to leak away to earth. Specifications:

QH66W in catalogue
The 555 is a highly stable device for generating accurate time delays or oscillation. Additional terminals are provided for triggering or resetting if desired. In the time delay (monostable) mode of operation the time is precisely controlled by one external resistor and one capacitor. For stable operation as an oscillator, the free running frequency and the duty cycle are both accurately controlled with two external resistors and one capacitor. The circuit may be triggered and reset on falling w

The MAX233 is a 2-line driver/receiver IC intended for all EIA/TIA-232E and V.28/V.24 communication interfaces, especially where no ±12V supply is available. The device includes on-board voltage convertors that require no external capacitors, which makes the IC suitable for battery-powered systems and applications where PCB space is critical. Data transfer rate is 120kbps. Supplied in a 20-pin DIL package.
only £5.99
CP88V in catalogue
A high quality audio-amp in a 5-pin TO220 package that does not require insulating washers between the metal tab and heatsink in single rail supply applications. The amp will operate with single or split supplies. The amp can provide 32W rms into a 4Ω load and 25W rms into 8Ω. The device features low harmonic and crossover distortion and a low external component count. The device includes short circuit protection and thermal shutdown.
only £3.99
FD92A in catalogue
A dual RS-232 receiver/transmitter that meets all the EIA RS-232C specifications while requiring only a single +5V supply. This significantly simplifies system design by removing the need to provide power supply voltages other than +5V. The IC has two on-board charge pump voltage convertors which generate +10V and -10V power supplies from the single +5V supply. The IC contains four level translators, two of which convert TTL/CMOS input levels into ±9V RS-232 outputs ready for transmission

RN73Q in catalogue
A black anodised, staggered vaned heatsink pre-drilled to accept TO3, TO66, SOT9, SOT32 and TO220 style cases. Temperature rise: 6°C/Watt.
N35CH in catalogue
A MOSFET input, bipolar output op-amp that will directly replace the 741 in most applications. It will operate from single or dual supply rails and input terminals can be swung up to 0.5V below negative rail. Internally compensated. Max input terminal current is 1mA. The output can be strobed. Supplied in an 8-pin DIL package. N35CH is RoHS compliant

YH64U in catalogue
The 13700 is a dual operational transconductance amplifier with linearising diodes and buffers. It consists of two current controlled transconductance amplifiers, each with different inputs and a push pull output. The two amplifiers share common supplies, but otherwise operate independently. Linearising diodes are provided at the inputs to reduce distortion and allow higher input levels. The result is a 10dB signal-to-noise improvement referenced to 0.5% THD. High impedance buffers are provided

The LM741 is a general purpose operational amplifier which feature improved performance over industry standards like the LM709. They are direct, plug-in replacements for the 709C, LM201, MC1439 and 748 in most applications. The amplifiers offer many features which make their application nearly foolproof: overload protection on the input and output, no latch-up when the common mode range is exceeded, as well as freedom from oscillations.

AV22Y in catalogue
A positive voltage regulator that can source 1A of output current with a dropout voltage of typically 0.5V and a maximum of 1V, over the entire temperature range. A quiescent current reduction circuit has been included which reduces the ground current when the differential between the input voltage and the output voltage exceeds approximately 3V. The quiescent current with 1A of output current and an input-output differential of 5V is therefore only 3mA. Higher quiescent currents only exists whe
