74ALVCH16843 18-bit bus-interface D-type latch; 3-State Rev. 3 — 20 November 2017 Product data sheet 1 General description The 74ALVCH16843 has two 9–bit D-type latch featuring separate D-type inputs for each latch and 3-State outputs for bus oriented applications. The two sections of each register are controlled independently by the latch enable (nLE), clear (nCLR), preset (nPRE) and output enable (nOE) control gates. When nOE is LOW, the data in the registers appear at the outputs. When nOE is HIGH, the outputs are in the high impedance OFF state. Operation of the nOE input does not affect the state of the flip-flops. The 74ALVCH16843 has active bus hold circuitry which is provided to hold unused or floating data inputs at a valid logic level.
