Name
Description When LOW, outputs LOW. When HIGH, data entered into latch. latch data inputs. latch enable input. latches transparent when HIGH. Input data latched HIGH-to-LOW transition. 3-state latch outputs. output enable control. When LOW, outputs enabled. When HIGH, outputs high-impedance (off) state. Preset line. When LOW, outputs HIGH LOW. Preset overrides CLR.
