Follows the input data while its latch-enable condition is active and retains it when that condition ends.

## What it represents

Follows the input data while its latch-enable condition is active and retains it when that condition ends.
On a schematic, identify the data input, latch-enable level and output-enable control and trace the retained data outputs and receiving circuit. Keep the component tag and signal/reference names consistent across the control drawing, terminal schedule and device documentation.
A transparent latch is level-sensitive; a D flip-flop captures data at a defined clock transition.
The preview is an independently drawn educational functional reference. Add the selected component’s actual power pins, terminal numbers, timing or analogue reference details when producing a construction drawing.

## How to read it

- Identify the data input, latch-enable level and output-enable control.
- Trace the retained data outputs and receiving circuit.

## Information to show or reference

- Label the data input, latch-enable level and output-enable control.
- Cross-reference the retained data outputs and receiving circuit.
- Add the selected device or circuit documentation revision, power/reference connections and project signal convention.

## Important distinction

A transparent latch is level-sensitive; a D flip-flop captures data at a defined clock transition.

## Facts

- Common schematic mnemonic: D-LATCH — descriptive only; project/device documentation defines reference designations.
- Terminal / interface focus: The data input, latch-enable level and output-enable control
- Artwork scope: Original educational functional/circuit reference; not a selected product pinout.
