What is buffer and latch?
A latch is a digital IC which holds the data put into it, 1 or 0, until cleared. An analog sample and hold performs a similar function in that it holds an analog value upon command until cleared. A buffer is either analog or digital, and it increases the power of the input signal without changing the value.
What is a compression latch?
Compression latches can provide a reliable solution to hold doors and panels shut while, at the same time, eliminating noise, panel movement, or rattling caused by vibration.For a precise fit and quick installation, a compression latch with a fixed-grip is often an ideal option.

What is gated D latch?
D stands for the Data latch, or D-latch, as it is generally called. The gated D-latch consists of. one R-S latch, and. two additional gates, which allow the latch to be set equal to the value of D, but only when WE is asserted (set to 1).
