CD74HC112MT

Overview

The CD74HC112MT is a dual J-K negative-edge-triggered flip-flop from Texas Instruments, housed in a 16-VSSOP package. It operates within a supply voltage range of 2V to 6V and supports a maximum clock frequency of 60 MHz. The device features asynchronous preset (/PRE) and clear (/CLR) inputs that override other inputs when active low. Propagation delay is specified at 30ns @ 6V with 50pF load. Output drive capability reaches ±5.2mA at 5V, while static current consumption is typically 4µA.

Feature Summary

• Dual independent J-K flip-flops with negative-edge triggering
• Asynchronous preset and clear control functions
• Wide operating voltage range for flexible system integration

Applications

• Parallel-to-serial data conversion circuits
• Shift register implementations
• Frequency division logic stages

Procurement Notes

Verify the specific suffix MT corresponds to the VSSOP-16 package variant during sourcing. Confirm RoHS compliance status and moisture sensitivity level (MSL) requirements against your assembly process specifications. Ensure the supplier provides valid traceability documentation for the Texas Instruments manufacturer part number.

Selection Notes

Select this component for designs requiring compact surface-mount integration of dual flip-flops. The VSSOP package offers space efficiency compared to DIP alternatives. Consider the 60 MHz clock limit and 30ns propagation delay for timing-critical high-speed applications within the 2V-6V operational window.

Part Context

This device belongs to the SNx4HCxx family of high-speed CMOS logic devices. It complements other HC-series components by providing essential sequential logic functionality in a small outline package. The technology ensures compatibility with standard 5V and lower voltage logic interfaces commonly found in modern embedded systems.

FAQ

How does the asynchronous clear function operate?

Applying a low level to the /CLR input immediately resets the Q output to a low state, regardless of the states of the J, K, or CLK inputs.

What is the trigger mechanism for data transfer?

Data from the J and K inputs is transferred to the output on the negative-going transition (falling edge) of the clock pulse.
