ENGINEERING LOGIC DIAGRAMS DOE-HDBK-1016/2-93 Logic Diagrams PR-05 Page 8 Rev. 0 Figure 9 Type-Three Time Delay Device Upon reciept of an input signal, Type-Three Time Delay Devices provide an output signal for a specified period of time, regardless of the duration of the input. Figure 9 demonstrates the signal response and illustrates the symbol used to denote the timer. Complex Logic Devices In addition to the seven basic logic gates, there are several complex logic devices that may be encountered in the use of logic prints. Memory devices - In many circuits, a device that can "remember" the last command or the last position is required for a circuit to function. Like the AND and OR gates, memory devices have been designed to work with on/off signals. The two input signals to a memory device are called set and reset. Figure 10 shows the common symbols used for memory devices.
