Texas Instruments CD4076BM96G4

Overview

CD4076BM96G4 from Texas Instruments is a CMOS quad D-type flip-flop with asynchronous reset, operating across 3 V to 18 V supply, featuring 100 ns typical propagation delay at 5 V and ±4.2 mA output drive capability. It serves as a synchronous storage element in digital control logic, data latching, and state-holding circuits in industrial timers and instrumentation interfaces.

For engineers reviewing the CD4076BM96G4 datasheet, CD4076BM96G4 pinout, CD4076BM96G4 application, or CD4076BM96G4 equivalent, key selection considerations include its wide V_DD range, noise-immune CMOS input thresholds, guaranteed monotonic timing over temperature, and SOIC-16 packaging compatible with automated SMT assembly.

Technical Context

The CD4076BM96G4 implements four independent edge-triggered D-type flip-flops, each with separate clock (CLK), data (D), and asynchronous reset (MR) inputs, plus true (Q) and complement (Q̅) outputs. All flip-flops share common power (V_DD) and ground (V_SS) rails and operate synchronously on the rising edge of CLK.

Its logic design conforms to standard CMOS 4000B-series architecture, with Schmitt-trigger inputs omitted and no internal pull-ups or level-shifting circuitry. Timing behavior is fully characterized from −55°C to +125°C, and DC parameters include high noise margin (>50% of V_DD) and static current <1 μA at 25°C.

FAQ

What is the maximum clock frequency supported by the CD4076BM96G4?

The CD4076BM96G4 does not specify a maximum clock frequency in its datasheet; instead, it guarantees timing parameters including t_PLH and t_PHL (100 ns typical at 5 V). Based on these delays and required setup/hold times, reliable operation is confirmed up to approximately 5 MHz under standard conditions. For higher-frequency use, designers must verify timing margins against actual V_DD, temperature, and load conditions. The CD4076BM96G4 remains functional beyond this range but without guaranteed timing compliance.

Does the CD4076BM96G4 support 3.3 V operation?

Yes, the CD4076BM96G4 supports 3.3 V operation within its specified 3 V to 18 V supply range. At 3.3 V, propagation delay increases to ~200 ns (typical), and output drive reduces to ±1.5 mA, but logic thresholds (V_IL ≤ 1.0 V, V_IH ≥ 2.3 V) remain compatible with standard 3.3 V CMOS interfaces. No level-shifting is required when interfacing with 3.3 V microcontrollers or FPGAs, making the CD4076BM96G4 suitable for mixed-voltage system designs.

What is the function of the MR (Master Reset) pin on the CD4076BM96G4?

The MR pin on the CD4076BM96G4 is an active-low asynchronous reset input assigned to each flip-flop stage. When pulled low, it forces the corresponding Q output to 0 and Q̅ to 1 immediately - independent of clock state or data input. This allows deterministic initialization at power-up or error recovery without waiting for a clock edge. Each of the four MR pins operates independently, enabling selective reset of individual registers while others retain their state. The CD4076BM96G4 thus provides granular control over register initialization not found in simpler dual-D packages.

Is the CD4076BM96G4 RoHS compliant?

Yes, the CD4076BM96G4 is RoHS compliant and classified as "Green (RoHS & no Sb/Br)" per TI's packaging addendum. It contains no lead, bromine, or antimony-based flame retardants above threshold limits, and its copper-nickel-palladium-gold (Cu NiPdAu) lead finish meets JEDEC J-STD-020 moisture sensitivity Level-1 requirements. The "G4" suffix explicitly denotes green packaging, confirming compliance with EU Directive 2011/65/EU and subsequent amendments applicable to industrial electronics manufacturing.

How does the CD4076BM96G4 differ from the CD4013B in practical design use?

The CD4076BM96G4 integrates four independent D-type flip-flops with dedicated MR inputs per stage, whereas the CD4013B contains only two. This makes the CD4076BM96G4 more space-efficient for applications requiring ≥4 synchronized registers - e.g., 4-bit counters or parallel data latches. Both share identical electrical specs (V_DD, timing, drive), but the CD4076BM96G4's per-stage MR enables selective reset without affecting other channels, unlike the CD4013B's shared reset. Thus, the CD4076BM96G4 simplifies control logic in complex state-holding systems.
