For example, if two identical amplifiers (each rated for operation into 4 ohm) are paralleled into a 4 ohm load, each amplifier sees an equivalent of 8 ohm since the output current is now shared by both amplifiers — each amplifier supplies half the load current, and the dissipation per amplifier is halved.
2 dual 4-bit buffer/driver, one inverted, one non-inverted; negative enable three-state: 20 SN74AS230: 74x231 2 dual 4-bit buffer/driver, both inverted; one positive and one negative enable three-state: 20 SN74AS231: 74x232 1 64-bit FIFO memory (16x4), asynchronous three-state: 16 SN74ALS232B: 74x233 1 80-bit FIFO memory (16x5), asynchronous ...
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 ...
A dual of a relationship is formed by interchanging voltage and current in an expression. The dual expression thus produced is of the same form, and the reason that the dual is always a valid statement can be traced to the duality of electricity and magnetism. Here is a partial list of electrical dualities: voltage – current
[6] [7] Indeed, it is capable of delivering 40 watts into 8 ohm, 58 watts into 4 ohm, and 72 watts into 2 ohm loads for a limited time if pushed. [8] The amplifier's main appeal was its inherent musicality, its ability to drive difficult speaker loads, and to allow audiophile grade source components to excel.
