CD74AC139/CD74ACT139 are dual 2-to-4-line decoders/demultiplexers that utilize the Harris Advanced CMOS Logic technology.

CD74AC138/CD74AC238 are 3-to-8-line decoders/demultiplexers that utilize the Harris Advanced CMOS Logic technology. Both circuits have three binary select inputs (A0, A1, and A2). If the device is enabled, these inputs determine which one of the eight normally HIGH outputs of the AC/ACT138 will go LOW or which on of the normally LOW outputs of the AC/ACT238 will go HIGH.

CD54AC112 and CD74AC112 are dual J-K negative-edge-triggered flip-flops with clear and preset. The device contains 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 is transferred to the outputs on the negative-going edge of the clock pulse (CLK). Clock triggering occurs at a voltage level and is not directly related to the fall 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. These versatile flip-flops can perform as toggle flip-flops by tying J and K high.
