A random input stream similar to the one shown in Figure 5 was applied to each input of the ALU. The current through the voltage supply pin for a 10 MHZ random input stream is shown in Figure 6. The average current for this case is 2.18 mA (8.51 mA RMS). Figure 7 shows the current through the voltage supply pin for a 50 MHZ random input stream.

TTL: Transistor-Transistor-Logic Topics The most commonly used bipolar logic family is transistor-transistor logic. Actually, there are many different TTL families, with a range of speed, power consumption, and other characteristics. The circuit examples in this section are based on a representative TTL family, Low-power Schottky (LS or LS-TTL).
