L293D IC Dual H-Bridge Motor Driver In Pakistan
The Device is a monolithic integrated high voltage, high current four channel driver designed to accept standard DTL or TTL logic levels and drive inductive loads (such as relays solenoids, DC, and stepping motors) and switching power transistors. To simplify use as two bridges each pair of channels is equipped with an enable input. A separate supply input is provided for the logic, allowing operation at a lower voltage, and internal clamp diodes are included. This device is suitable for use in switching applications at frequencies up to 5 kHz. The L293D is assembled in a 16-lead plastic package that has 4 center pins connected together and used for heatsinking.

24C64 Serial EEPROM 64K Memory IC In Pakistan
24C64 is a 64Kbit CMOS non-volatile serial EEPROM organized as 8K x 8-bit memory. This Memory IC confirms to Extended IIC 2-wire protocol that allows accessing of memory in excess of 16Kbit on an IIC bus. This serial communication protocol uses a Clock signal (SCL) and a Data signal (SDA) to synchronously clock data between a master (e.g. a microcontroller) and a slave (EEPROM). 24C64 is designed to minimize pin count and simplify PC board layout requirements. 24C64 offers hardware write protection whereby the entire memory array can be write-protected by connecting the WP pin to VCC. This section of memory then becomes unalterable until the WP pin is switched to VSS. This device is offered in SO, TSSOP, and DIP packages.

LM7805 L7805 7805 Linear Voltage Regulator IC In Pakistan
The LM7805CV is a fixed output, three-terminal precision positive voltage regulator in 3 pins TO-220 package. This regulator can provide local on-card regulation by eliminating distribution problems associated with single-point regulation. The L7805 fixed voltage regulator is designed with thermal overload protection that shuts down the circuit when subjected to an excessive power overload condition, internal short circuit protection that limits the maximum current the circuit will pass, and output transistor safe area compensation that reduces the output short circuit as the voltage across the pass transistor is increased. If adequate heat sinking is provided then this positive voltage regulator can deliver over 1A output current.
