Compare the meaning, drawing context and source references of two entries. A similar graphic or shared abbreviation does not establish equivalence.
S/H
SymbolsSample-and-hold amplifier
Acquires an analogue signal during the documented sampling interval and retains a representation during hold.

A distinction that matters
Hold behaviour is an analogue acquisition function; it differs from digital storage in a latch or flip-flop.
D-FF
SymbolsPositive-edge D flip-flop
Captures its data input at the documented positive clock edge and retains that digital state.

- Application
- Logic & signals
- Reference family
- Manufacturer
A distinction that matters
An edge-triggered flip-flop differs from a transparent latch; data timing relative to the clock remains essential.
