SN74F112 具有清零和预设功能的双路 J-K 下降沿触发器
The SN74F112 contains two independent J-K negative-edge-triggered flip-flops. A low level at the preset (
) or clear (
) inputs sets or resets the outputs regardless of the levels of the other inputs. When and are inactive (high), data at the J and K inputs meeting the setup time requirements is transferred to the outputs on the negative-going edge of the clock pulse. Clock triggering occurs at a voltage level and is not directly related to the rise time of the clock pulse. Following the hold-time interval, data at the J and K inputs may be changed without affecting the levels at the outputs. The SN74F112 can perform as a toggle flip-flop by tying J and K high.
The SN74F112 is characterized for operation from 0°C to 70°C
