74AC11898
description
The 74AC11898 features
AND-gated serial inputs and an asynchronous clear. The gated serial inputs (A and B) permit plete control over ining data. A low at either input inhibits entry of new data and resets the first flip-flop to the low level on the rising edge of the next clock pulse. A high-level input enables the other input, which then determines the state of the first flip-flop. Data at the serial inputs may be changed while the clock is high or low provided the minimum setup and hold time requirements are met. Clocking occurs on the low-to-high transition of the clock input.
The 74AC11898 is characterized for operation from
- 40°C to 85°C.
