Dual J-K Flip-Flop with Set and Reset
Negative-Edge Trigger
Description
The ’HC112 and ’HCT112 utilize silicon-gate CMOS
technology to achieveoperating speeds equivalent to LSTTL
parts. They exhibit the low power consumption of standard
CMOS integrated circuits, together with the ability to drive 10
LSTTL loads.
These flip-flops have independent J, K, Set, Reset, and
Clock inputs and Q and
negative-going transition of the clock pulse. Set and Reset
are accomplished asynchronously by low-level inputs.
The HCT logic family is functionally as well as pincompatible with the standard LS logic family.

Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check
http://www.ti.com/productcontent for the latest availability information and additional product content details.
TBD: The Pb-Free/Green conversion plan has not been defined.
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements
for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered
at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and
package, or 2) lead-based die adhesive used between the die and leadframe. The component is otherwise considered Pb-Free (RoHS
compatible) as defined above.
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame
retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material)
