Logic - Latches

Category Introduction

Latches are elementary digital memory devices similar to flip-flops, but different in that the retained logic state can change at any time a latch enable (or similarly named) signal is in a valid logic state. Latches described as "transparent" further allow the device outputs to reflect the current state of the inputs while the latch enable signal is valid, as opposed to changing state only when the retained state has been fixed.
