ULN2003A pinout Simplified ULN2003A logical pinout diagram.. The ULN2003A is an integrated circuit produced by Texas Instruments.It consists of an array of seven NPN Darlington transistors capable of 500 mA, 50 V output.
Transistor–transistor logic (TTL) is a logic family built from bipolar junction transistors.Its name signifies that transistors perform both the logic function (the first "transistor") and the amplifying function (the second "transistor"), as opposed to earlier resistor–transistor logic (RTL) and diode–transistor logic (DTL).
The 7400 series is a popular logic family of transistor–transistor logic (TTL) integrated circuits (ICs). [ 3 ] In 1964, Texas Instruments introduced the SN5400 series of logic chips, in a ceramic semiconductor package .
Open collector, open drain, open emitter, and open source refer to integrated circuit (IC) output pin configurations that process the IC's internal function through a transistor with an exposed terminal that is internally unconnected (i.e. "open").
Schematics from the Eccles and Jordan trigger relay patent filed 1918, one drawn as a cascade of amplifiers with a positive feedback path, and the other as a symmetric cross-coupled pair The first electronic latch was invented in 1918 by the British physicists William Eccles and F. W. Jordan .
MAX232 chip in DIP-16 package The die of a MAX232 MAX232 pinout: Red: power, Yellow: charge pump capacitors, Blue: outputs, Green: inputs, Pins 9–12: TTL/CMOS I/O voltages. The MAX232 is an integrated circuit by Maxim Integrated Products, now a subsidiary of Analog Devices, that converts signals from a TIA-232 (RS-232) serial port to signals suitable for use in TTL-compatible digital logic ...
Julius Edgar Lilienfeld proposed the concept of a field-effect transistor in 1925.. The thermionic triode, a vacuum tube invented in 1907, enabled amplified radio technology and long-distance telephony.
