SN74AS876NT

This dual 4-bit D-type edge-triggered flip-flop from Texas Instruments, model SN74AS876NT, is designed for bus-structured applications. It features 3-state, inverted outputs that can drive bus lines directly, making it suitable for buffer registers, I/O ports, and working registers. The device enters data on the low-to-high transition of the clock input and includes a master reset function.

The SN74AS876NT operates over a temperature range of 0°C to 70°C (TA) and requires a supply voltage between 4.5V and 5.5V, consuming approximately 142 mA. It supports a maximum clock frequency of 80 MHz with a propagation delay of 10.5 ns at 5V and 50pF. The flip-flop is housed in a 24-pin DIP package (0.300" width) and is designed for through-hole mounting.

Key electrical characteristics include its dual 4-bit configuration, D-type input, positive edge triggering, and tri-state inverted outputs. The asynchronous master reset allows for immediate clearing of the flip-flop states independently of the clock. This component is particularly useful in digital systems requiring efficient data buffering and transfer.

Packaged in a standard 24-pin Dual In-line Package (DIP), the SN74AS876NT is suitable for through-hole mounting. Its operating temperature range of 0°C to 70°C makes it appropriate for various industrial and commercial applications. The device's robust design and specific features like tri-state outputs and master reset provide flexibility in digital circuit design.
