74138 ic 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 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.
