HD74ALVCH16827 is a 20-bit buffer/driver with 3-state outputs. It is composed of two 10-bit sections with separated output enable signals. For either 10-bit buffer section, the two output enable (1OE1 and 1OE2 or 2OE1 and 2OE2) inputs must both be low for the corresponding Y outputs to be active. If either output enable input is high, the outputs of that 10-bit buffer section are in the high impedance state. Active bus hold circuitry is provided to hold unused or floating data inputs at a valid logic level.
The HD74ALVCH16827 is a 20‑bit buffer/driver with two independent 10‑bit sections and separate output‑enable signals. It offers high output current, bus‑hold on inputs, and operates from a supply voltage of 2.3 V to 3.6 V under recommended conditions.
