SNJ54HC112W DUAL J-K NEGATIVE-EDGE-TRIGGERED FLIP-FLOPS

ordering information 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 outp.

Features

These versatile flip-flops perform as toggle flip-flops by tying J and K high. SN54HC112 . . . J OR W PACKAGE SN74HC112 . . .
