Regular-speed TTL parts were also available for a time in the 6400 series – these had an extended industrial temperature range of −40 °C to +85 °C. While companies such as Mullard listed 6400-series compatible parts in 1970 data sheets, [21] by 1973 there was no mention of the 6400 family in the Texas Instruments TTL Data Book.
For example, the 7404 TTL chip which has 14 pins and the 4049 CMOS chip which has 16 pins, 2 of which are used for power/referencing, and 12 of which are used by the inputs and outputs of the six inverters (the 4049 has 2 pins with no connection).
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 ]
A TTL input signal is defined as "low" when between 0 V and 0.8 V with respect to the ground terminal, and "high" when between 2 V and V CC (5 V), [22] [23] and if a voltage signal ranging between 0.8 V and 2.0 V is sent into the input of a TTL gate, there is no certain response from the gate and therefore it is considered "uncertain" (precise ...
Multiple-emitter transistors replace the diodes of diode–transistor logic (DTL) to make transistor–transistor logic (TTL), [1] and thereby allow reduction of switching time and power dissipation.

Inverter is common (the TTL 7404 is a hex inverter rather than a hex not gate) and makes more sense. NOT gate puts the function into an AND, OR, XOR gate parallel naming scheme, but a single input function confuses the meaning of "gate". Glrx 18:41, 17 April 2012 (UTC)
