SN74F112NS

Flip Flops Overview

The SN74F112NS is a dual J-K flip-flop from Texas Instruments' SN74F logic series, housed in a 14-pin DIP package. It features negative-edge triggering with independent set and reset inputs. The device operates on a single 5V supply (4.5V to 5.5V) and supports a maximum clock frequency of 130 MHz. Key electrical parameters include a propagation delay of 6.5 ns at 5V with 50pF load, high-level output current of -1 mA, and low-level output current of 20 mA. It functions within a temperature range of 0°C to +70°C.

Flip Flops Feature Summary

• Dual J-K flip-flops with negative-edge triggered operation
• Independent active-low set and reset control inputs
• Complementary Q and Q-bar outputs for differential signaling

Flip Flops Applications

• High-speed digital counters
• Shift register construction
• Frequency division circuits
• State machine implementation

Flip Flops Procurement Notes

Verify the specific suffix 'NS' corresponds to the standard 14-pin PDIP package rather than tape-and-reel variants like 'NR'. Confirm RoHS compliance status as per the latest manufacturer documentation. Ensure the supplier provides valid traceability for the Texas Instruments brand. Check for any recent product change notices affecting pinout or electrical characteristics before finalizing procurement orders.

Flip Flops Selection Notes

Select this component when negative-edge triggering is required for precise timing synchronization in F-series logic applications. The 130 MHz clock capability suits high-speed designs compared to slower HC or HCT families. Ensure the design accommodates the bipolar technology power consumption and output drive requirements. Verify that the DIP-14 package fits the mechanical constraints of the target PCB layout.

Flip Flops Part Context

This part belongs to the Texas Instruments SN74F family, known for fast switching speeds using bipolar transistor technology. The SN74F112 specifically implements dual J-K flip-flops, a fundamental building block for sequential logic. It contrasts with D-type variants like the SN74F74 by offering toggle functionality via the J and K inputs, enabling more complex state transitions in digital systems.
