Schematic of basic two-input DTL NAND gate. R3, R4 and V− shift the positive output voltage of the input DL stage below the ground (to cut off the transistor at low input voltage). Diode–transistor logic (DTL) is a class of digital circuits that is the direct ancestor of transistor–transistor logic.
Diode logic (or diode-resistor logic) constructs AND and OR logic gates with diodes and resistors. An active device ( vacuum tubes with control grids in early electronic computers , then transistors in diode–transistor logic ) is additionally required to provide logical inversion (NOT) for functional completeness and amplification for voltage ...
The simplest family of logic gates uses bipolar transistors, and is called resistor–transistor logic (RTL). Unlike simple diode logic gates (which do not have a gain element), RTL gates can be cascaded indefinitely to produce more complex logic functions. RTL gates were used in early integrated circuits.
Diode–transistor logic (DTL) was used in the IBM 608 which was the first all-transistorized computer. Early transistorized computers were implemented using discrete transistors, resistors, diodes and capacitors. The first diode–transistor logic family of integrated circuits was introduced by Signetics in 1962.
Schematic of basic unbuffered three-input HTL NAND gate. High-threshold logic (HTL), also known as low-speed logic (LSL) or high-level logic (HLL), is a variant of diode–transistor logic used in environments where noise is very high. FZH251, four two-input HTL AND
A NAND gate is made using transistors and junction diodes. By De Morgan's laws , a two-input NAND gate's logic may be expressed as A ¯ ∨ B ¯ = A ⋅ B ¯ {\displaystyle {\overline {A}}\lor {\overline {B}}={\overline {A\cdot B}}} , making a NAND gate equivalent to inverters followed by an OR gate .
A wired logic connection is a logic gate that implements boolean algebra (logic) using only passive components such as diodes and resistors. A wired logic connection can create an AND or an OR gate. Limitations include the inability to create a NOT gate, the lack of amplification to provide level restoration, and its constant ohmic heating for ...
