Description

The ’HC112 devices contain two independent J-K negative-edge-triggered flip-flops. A low level at the preset (PRE)\ or clear (CLR)\ inputs sets or resets the outputs, regardless of the levels of the other inputs. When (PRE)\ and (CLR)\ are inactive (high), data at the J and K inputs meeting the setup time requirements are transferred to the outputs on the negative-going edge of the clock (CLK) pulse. Clock triggering occurs at a voltage level and is not directly related to the fall time of the CLK pulse. Following the hold-time interval, data at the J and K inputs may be changed without affecting the levels at the outputs. These versatile flip-flops perform as toggle flip-flops by tying J and K high.

AC-Coupled RS-485 Reference Design
TIDA-01171 — The TIDA-01171 reference design allows for RS-485 communication over an AC-coupled link, even at very low data rates.  This allows for nodes to communicate even when large ground potential differences exist between nodes.  Using AC coupling also helps to protect transceivers from bus (...)
