Each I/O cell has two flip- flops, up to three sum terms, individual clock, reset, and preset terms per flip-flop, and one output enable term. Independent of output configuration, all flip-flops are always usable, and have at least four product term inputs each. Each I/O pin (52 total) signal or its latched version drives the logic array. There is one latch clock per quadrant. The ATV5000 has four identical quadrants (see Figure 2). The universal bus routes true and false signals from each of the 52 I/O pins to all four quadrants. Regional buses route each quad- rant’s flip-flop Q and Q locally. The eight input-only pins are available in all four regional buses. Each logic cell has a number of "regional" and "universal" prod- uct terms (see Figure 1). The I/O logic cells contain three sum terms, two flip-flops, and an I/O buffer. The buried logic cells each contain one flip-flop. In addition, in each buried logic cell the sum term can drive the regional bus. This allows for logic expansion. Serial register preload and observability simplify testing. All registers automatically clear at power up.

This is a stress rating only and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect de- vice reliability. Note: 1. Minimum voltage is -0.6 V dc which may undershoot to -2.0 V for pulses of less than 20 ns. Maximum output pin voltage is VCC+0.75 V dc which may overshoot to +7.0 V for pulses of less than 20 ns.
