The 74S181 4-bit ALU bitslice resting on a page from the datasheet The 74181 is a 4-bit slice arithmetic logic unit (ALU), implemented as a 7400 series TTL integrated circuit . Introduced by Texas Instruments in February 1970, [ 1 ] it was the first complete ALU on a single chip. [ 2 ]
In 1964, Texas Instruments introduced the SN5400 series of logic chips, in a ceramic semiconductor package. A low-cost plastic package SN7400 series was introduced in 1966 which quickly gained over 50% of the logic chip market, and eventually becoming de facto standardized electronic components.
Texas Instruments TMS1100 microcontroller inside the Parker Brothers Merlin electronics game. The TMS1000 is a family of microcontrollers introduced by Texas Instruments in 1974. [ 1 ] [ 2 ] [ 3 ] It combines a 4-bit central processor unit , read-only memory (ROM), random access memory (RAM), and input/output (I/O) lines as a complete "computer ...
Some TTL logic parts were made with an extended military-specification temperature range. These parts are prefixed with 54 instead of 74 in the part number. [1]A short-lived 64 prefix on Texas Instruments parts indicated an industrial temperature range; this prefix had been dropped from the TI literature by 1973.
The following is a list of CMOS 4000-series digital logic integrated circuits.In 1968, the original 4000-series was introduced by RCA.Although more recent parts are considerably faster, the 4000 devices operate over a wide power supply range (3V to 18V recommended range for "B" series) and are well suited to unregulated battery powered applications and interfacing with sensitive analogue ...
Texas Instruments and other brands of 7400 series TTL and CMOS logic Texas Instruments Speak & Spell using a TMC0280 speech synthesizer TI-30 electronic calculator, 1976. The 7400 series of transistor-transistor logic chips, developed by Texas Instruments in the 1960s, popularized the use of integrated circuits in computer logic. The military ...
List of free analog and digital electronic circuit simulators, available for Windows, macOS, Linux, and comparing against UC Berkeley SPICE. The following table is split into two groups based on whether it has a graphical visual interface or not.
The TMS1100 is a family of microcontrollers introduced by Texas Instruments in 1975. This type of microprocessors are an expanded memory version of the TMS1000. [1] The 1100 is built on PMOS technology [2] with clock speed is 400 kHz. [3] with 43 Standard Instructions and 1024 Micro- instructions. TMS1100
