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 ...

74LVC1T45, 1-bit bidirectional with direction control, dual-supply of 1.65V-5.5V translated to 1.65V-5.5V, available only in SMD packages. 2-bit 74LVC2T45 and 8-bit 74LVC8T245 exist too. 4504B , 6-bit unidirectional, dual-supply of 5V TTL or 5V-18V CMOS translated to 5V-18V CMOS, available in DIP or SMD packages.
For a given fixed I CA, a 1 V rise in V CA must be offset with ≈1.4 mV (2.7 mV worst-case maximum) [13] decrease in V REF. The ratio μ = 1 V / 1.4 mV ≈ 300–1000, or ≈ 50–60 dB is the theoretical maximum open-loop voltage gain at DC and low frequencies; [16]
The 4000 series is a CMOS logic family of integrated circuits (ICs) first introduced in 1968 by RCA. [1] It was slowly migrated into the 4000B buffered series after about 1975. [ 2 ] It had a much wider supply voltage range than any contemporary logic family (3V to 18V recommended range for "B" series).
TI-36X Solar, 1993 Revision TI-36X Solar, 2004 Revision. The design was similar on the 1991 version of TI-68, but without programming features and tilt screen, and only uses 7-segment LCD display. The double shift keys are remained. Base calculations were updated to include logic operations (NOT, AND, OR, XOR, XNOR).
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 ]
