74AC11898 Overview
Description
The 74AC11898 features AND-gated serial inputs and an asynchronous clear. The gated serial inputs (A and B) permit complete control over incoming data.
Key Features
- AND-gated serial inputs and an asynchronous clear
- The gated serial inputs (A and B) permit complete control over incoming 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
- FUNCTION TABLE INPUTS OUTPUTS CLR CLK LX A X B QA QB
- Qn, Qin = the level or QA or QJ before the most recent ↑ transition of the clock; indicates a one-bit shift
