CD4042 Quad Clocked D Latch

The CD4042 is a quad clocked D latch IC, containing four independent D-type (data) latches that capture and hold their input state when triggered by a clock signal.

Each latch transfers its data input to the output on the active clock edge/level and holds that value until the next clock trigger, a fundamental building block for simple data storage and synchronization circuits.

Part of the CD40xx CMOS logic family, this IC is a standard building block for clocked data storage circuits.

Features:

1. Quad clocked D-type latch (4 independent latches)
2. Clock-triggered data capture and hold
3. Part of the CD40xx CMOS logic family
4. Suited for data storage and synchronization circuits
