Topic 3 Digital Logic Signal & gg g Device Notations Akash Kumar utline Outline Transistor-transistor Logic (TTL) Parts. Signal Naming Conventions. The Positive Logic Convention and Logic Gate epresentations. Representations. SSI Basic Gate Summary. Interpreting Signals in Digital Circuit Diagrams. 2 igital Devices Digital Devices Digital devices are manufactured under various technologies such as TTL, CMOS, NMOS, etc. Small scale integrated (SSI) circuit chips contain less than 12 gates and are commonly available as TTL parts. SI chips contain between 13 and 99 gates, LSI MSI chips contain between 13 and 99 gates, LSI between 100 and 1000, and VLSI more than 000 These chips are available in various 1000. These chips are available in various families. 3 ransistor ansistor logic (TTL) parts Transistor-transistor logic (TTL) parts The TTL family includes many different series such as Standard TTL High speed H-TTL Low Power L-TTL chottky - TL Schottky S TTL Low power Schottky LS-TTL d anced Schottk S TL Advanced Schottky AS-TTL Advanced LS ALS-TTL 4
