SN74HC112DT

Flip Flops Overview

The SN74HC112DT is a dual J-K flip-flop from Texas Instruments' 74HC logic family, housed in a 16-SOIC surface-mount package. It features negative-edge triggering with independent preset (/PRE) and clear (/CLR) inputs that operate asynchronously. The device supports a supply voltage range of 2V to 6V and operates within a temperature range of -40°C to 85°C. Key electrical characteristics include a maximum propagation delay of 21ns at 6V with 50pF load, static current of 4µA, and output drive capability of ±5.2mA.

Flip Flops Feature Summary

• Dual negative-edge triggered J-K flip-flops with asynchronous active-low preset and clear functions
• Wide operating voltage range supporting 2V to 6V supply rails
• Low power consumption with maximum static current of 4µA
• High noise immunity and output drive capability for driving multiple LSTTL loads

Flip Flops Applications

• Server systems
• LED display controllers
• Network switch infrastructure
• Telecommunications equipment
• Motor driver interfaces

Flip Flops Procurement Notes

Verify the specific ordering suffix 'DT' corresponds to the 16-SOIC tape-and-reel or cut-tape packaging configuration. Confirm RoHS3 compliance status as indicated by recent product change notices. Ensure the selected quantity matches distributor reel or cut-tape minimums. Cross-reference the manufacturer part number against authorized channel listings to guarantee authenticity and traceability.

Flip Flops Selection Notes

Select this component when dual J-K functionality with asynchronous control is required in space-constrained designs. The SOIC package suits automated surface-mount assembly processes. Consider the 2V-6V voltage range for compatibility with various logic levels. Evaluate the 21ns propagation delay against system timing requirements to ensure signal integrity across the application's operational frequency.

Flip Flops Part Context

This part belongs to the SNx4HC112 family, which includes variants like the through-hole SN74HC112N and other package options. The SN74HC112DT specifically denotes the small-outline integrated circuit (SOIC) version manufactured by Texas Instruments. It shares functional specifications with other family members but differs in physical footprint and mounting style, catering to different PCB layout constraints.

Flip Flops Replacement Considerations

Public confirmed substitute part numbers include SN74HC112DTE4 and SN74HC112DTG4.
