# DigiSim Logic Components

> Reference for digital logic components in DigiSim with pin configurations and behavior.

## Input Components
- **INPUT_SWITCH**: Manual toggle (1 output)
- **CLOCK**: Configurable frequency generator (1Hz default)
- **CONSTANT/CONSTANT_ZERO**: Fixed logic values

## Logic Gates
- **AND/NAND**: 2-8 inputs, output=1 when all inputs=1 (inverted for NAND)
- **OR/NOR**: 2-8 inputs, output=1 when any input=1 (inverted for NOR)
- **XOR/XNOR**: 2-8 inputs, exclusive OR operation (inverted for XNOR)
- **NOT**: 1 input inverter
- **BUFFER**: Non-inverting signal conditioner

## Sequential Logic
- **D_FLIP_FLOP**: Data storage with clock (D, CLK, PRE, CLR, Q, Q̅)
- **JK_FLIP_FLOP**: Universal flip-flop with toggle (J, K, CLK, PRE, CLR, Q, Q̅)
- **T_FLIP_FLOP**: Toggle flip-flop (T, CLK, CLR, Q, Q̅)
- **SR_LATCH**: Set-reset latch (S, R, Q, Q̅)
- **D_LATCH**: Transparent latch (D, EN, Q, Q̅)

## Memory Components
- **REGISTER_8BIT**: 8-bit parallel register (D0-D7, CLK, CLR, Q0-Q7)
- **COUNTER_8BIT**: 8-bit binary counter (CLK, CLR, EN, Q0-Q7, Carry)
- **RAM/ROM**: Memory with address/data buses

## Arithmetic
- **ALU_8BIT**: 8-bit arithmetic logic unit with operations and flags
- **BINARY_ADDER**: Multi-bit addition (A, B, Cin, Sum, Cout)
- **COMPARATOR**: Magnitude comparison (A>B, A=B, A<B)

## Data Routing
- **MULTIPLEXER**: Data selector (many-to-one)
- **DEMULTIPLEXER**: Data distributor (one-to-many)
- **ENCODER/DECODER**: Priority encoding and binary decoding
