TEXAS INSTRUMENTS CD74HCT112E JK Flip-Flop, Negative Edge Triggered, 16-Pin DIP

The TEXAS INSTRUMENTS CD74HCT112E is a dual negative-edge-triggered J-K flip-flop with independent set and reset functions, providing reliable and versatile logic control. It leverages advanced silicon-gate CMOS technology to deliver high-speed operation equivalent to LSTTL components while maintaining the low power consumption characteristic of CMOS integrated circuits. This efficient design allows it to drive up to 10 LSTTL loads, making it a powerful and energy-saving choice for digital logic applications.

Each flip-flop features independent J, K, Set, Reset, and Clock inputs, alongside complementary Q and Q̅ outputs for maximum design flexibility. State changes occur on the negative-going transition of the clock pulse, and asynchronous set and reset are accomplished via low-level inputs. The HCT logic family ensures both functional and pin-for-pin compatibility with the standard LS logic family, facilitating easy upgrades and replacements in existing designs.

Key Features & Benefits

• High Noise Immunity: Hysteresis on the clock inputs improves noise immunity and allows for increased input rise and fall times, ensuring stable operation in electrically noisy environments.
• Asynchronous Control: Independent set and reset inputs provide immediate control over the output state, regardless of the clock signal.
• Efficient Power Usage: Offers significant power reduction compared to traditional LSTTL logic integrated circuits.
• Wide Compatibility: Features direct LSTTL input logic compatibility and CMOS input compatibility, with bus driver outputs capable of handling 15 LSTTL loads.
• Balanced Performance: Buffered inputs and balanced propagation delay and transition times contribute to reliable and predictable circuit timing.

This integrated circuit is supplied in a standard 16-pin Dual In-line Package (DIP), making it suitable for through-hole PCB assembly. Its -55
