description

The ´ABT16377 is a 16-bit positive-edge-triggered D-type flip-flop with a clock (1CLK or 2CLK) input. It is particularly suitable for implementing buffer and storage registers, shift registers, and pattern generators.

The device can be used as two 8-bit flip-flops or one 16-bit flip-flop. On the positive transition of the clock input, the Q outputs of the flip-flop take on the logic levels set up at the data (D) inputs.

Data input information that meets the setup time requirements is transferred to the Q outputs on the positive-going edge of the clock pulse if the common clock-enable (1 or 2) input is low. Clock triggering occurs at a particular voltage level and is not directly related to the transition time of the positive-going pulse. When the buffered clock input is at either the high or low level, the D input signal has no effect at the output. The circuits are designed to prevent false clocking by transitions at .

The SN74ABT16377 is available in TI's shrink small-outline package (DL), which provides twice the I/O pin count and functionality of standard small-outline packages in the same printed-circuit-board area.

The SN54ABT16377 is characterized for operation over the full military temperature range of -55°C to 125°C. The SN74ABT16377 is characterized for operation from -40°C to 85°C.
