CD4076BMT

Overview

The CD4076BMT is a CMOS quad D-type register manufactured by Texas Instruments, housed in a 16-SOIC surface-mount package. It operates on a supply voltage range of 3V to 18V and supports a maximum clock frequency of 16 MHz. The device features positive-edge triggering, three-state non-inverting outputs, and an asynchronous reset function. Key electrical parameters include a propagation delay of 180 ns at 15V with 50pF load, output currents of ±6.8mA, and static current of 20 µA. It functions within a temperature range of -55°C to +125°C.

Feature Summary

• Contains four independent D-type flip-flops with positive-edge clock triggering for sequential data storage.
• Provides three-state outputs allowing direct bus interfacing and system-level signal isolation.
• Includes an asynchronous reset input to force all outputs to a defined low state independently of the clock.

Applications

• Parallel-to-serial or serial-to-parallel data conversion circuits
• Shift register implementations in digital logic systems
• Memory buffer stages in microprocessor-based interfaces

Procurement Notes

Verify the specific suffix 'MT' confirms the 16-SOIC surface-mount package and tape-and-reel availability. Confirm RoHS compliance status matches current manufacturing standards. Ensure the supplier source provides official datasheets matching the Texas Instruments part number to avoid counterfeit components. Check for any recent product change notifications affecting pinout or electrical characteristics.

Selection Notes

Select this component when a compact surface-mount solution for quad D-type latching is required. It is suitable for designs needing three-state output control for shared bus architectures. Consider the 16 MHz operating limit and 18V maximum rating against system requirements. Compare against through-hole variants like CD4076BE if assembly methods differ.

Part Context

This part belongs to the Texas Instruments 4000B series of CMOS logic devices. It serves as a fundamental building block for sequential logic circuits. The SOIC package facilitates automated surface-mount assembly processes. It complements other logic gates and counters within the same family for complex digital system design.

FAQ

What is the trigger edge for the CD4076BMT?

The device uses positive-edge triggering for data capture on the clock input.

Does the CD4076BMT have active-high or active-low outputs?

The outputs are non-inverting, meaning they reflect the Q state directly.
