Texas Instruments SN74ABT16823 18-Bit Bus Interface Flip-Flops With 3-State Outputs SN74ABT16823DGVRE4

The SN74ABT16823 is an 18-bit bus interface flip-flop featuring 3-state outputs, designed for driving capacitive or low-impedance loads. It can function as either two 9-bit flip-flops or one 18-bit flip-flop. The device operates with a clock-enable (CLKEN) input that allows data entry on the rising edge of the clock when low, while a clear (CLR) input can independently set the outputs low. The buffered output-enable (OE) input places the outputs in a high-impedance state, allowing for bus line driving without additional components. This flip-flop is characterized for operation from -40¬8C to 85¬8C and features high-drive outputs with a current capability of -32 mA for sourcing and 64 mA for sinking. The device also includes ESD protection exceeding 2000 V per MIL-STD-883, ensuring reliability in various applications. Its flow-through architecture aids in optimizing PCB layout, and it is available in multiple package options, including plastic and ceramic variants.
