The 74ALVCH16843 has two 9
The Philips 74ALVCH16843 is an 18-bit bus-interface D-type latch featuring two 9-bit sections with separate D-type inputs and 3-State outputs. It is designed for bus-oriented applications, offering independent control for each section via Latch Enable (nLE), Clear (nCLR), Preset (nPRE), and Output Enable (nOE) gates. The device includes active bus hold circuitry to maintain valid logic levels on unused or floating inputs, eliminating the need for external pull-up or pull-down resistors.
