Rochester Electronics Logic - Flip Flops SN74ALVCH16821DL

The SN74ALVCH16821DL is a 20-bit bus-interface flip-flop designed for operation within a supply voltage range of 1.65 V to 3.6 V. It can function as two separate 10-bit flip-flops or as a single 20-bit flip-flop, providing true data at the Q outputs on the positive edge of the clock input. The device features a buffered output-enable (OE) input, allowing the outputs to be placed in a high-impedance state, which facilitates bus driving without the need for external pull-up or pull-down resistors. This flip-flop includes active bus-hold circuitry that maintains unused or undriven inputs at a valid logic state, eliminating the requirement for additional resistors. The device's latch-up performance exceeds 250 mA per JESD 17, and it offers ESD protection that surpasses JESD 22 standards, with ratings of 2000 V for the Human-Body Model and 200 V for the Machine Model. The operating temperature range is specified from -40 °C to 85 °C, making it suitable for a variety of applications.
