LM380 - 2.5W
Audio Power Amplifier IC for consumer applications. Amplifier gain is internally fixed at
34 dB. Input stage allows ground referenced input signals and utput automatically
self-centers to one-half the supply voltage. The output is short circuit proof with
internal thermal limiting.
LM741 - old and not very good operational amplifier, usable in
non-demandign applications
KA7805 -
3-Terminal 1A Positive Voltage Regulator for 5V output voltage
LM78xx series
positive voltage regulators - up to 1A regulator at constant voltages (7805=+5V,
7808=+8V, 7812=+12V, 7815=+15V, 7818=+18V), includes overcurrent and therminal protection,
input voltage range from output voltage + 2V to 24V, 7805 voltage regulator IC form this
series for 5V output is very useful for powering your TTL logic
circuits

pin variable voltage regulator for 1.2V to 37V and up to 1.5A current
Interfacing ICs
MAX232 - very
useful and easy to use RS-232 transmitter and receiver using single +5V power supply from Maxim
ULN2803
- 8-bit 50V 500mA TTL compatible input NPN darlington driver. This driver is suitable for
loads like lamps, relays printer hammers or other similar loads for a broad range of
computer, industrial, and consumer applications. This device featurs open-collector
outputs and free wheeling clamp diodes for transient suppression. The ULN2803 is designed
to be compatible with standard TTL families.
ULN2804
- 8-bit 50V 500mA CMOS/PMOS compatible input NPN darlington driver. This driver is
suitable for loads like lamps, relays printer hammers or other similar loads for a broad
range of computer, industrial, and consumer applications. This device featurs
open-collector outputs and free wheeling clamp diodes for transient suppression. The
ULN2804 is optimized for 6 to 15 volt high level CMOS or PMOS.

74xxx databook - pinlayout, the connectionlayout, an functiontable and the most
important specifications available for most important 7400 series ICs
LM3914 Dot/Bar
Display Drive - The LM3914 is a monolithic integrated circuit that senses analog
voltage levels and drives 10 LEDs, providing a linear analog display. A single pin changes
the display from a moving dot to a bar graph. Current drive to the LEDs is regulated and
programmable, eliminating the need for resistors.
