SN54HC109, SN74HC109 SCLS470C - MARCH 2003 - REVISED JUNE 2022 SNx4HC109 Dual J-K Positive-Edge-Triggered Flip-Flops With Clear and Preset 1 Features - Wide operating voltage range of 2 V to 6 V - Low input current of 1 μA max - High-current outputs drive up to 10 LSTTL loads - Low power consumption, 40-μA max ICC - Typical tpd = 12 ns - ±4-mA output drive at 5 V 2 Description These devices contain two independent J-K positiveedge-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...
