Texas Instruments CD4013BMG4

Overview

CD4013BMG4 from Texas Instruments is a CMOS dual D-type flip-flop in 14-pin SOIC package, featuring two independent edge-triggered storage elements with asynchronous set/reset, 3–18 V supply range, and 16 MHz max clock toggle rate at 10 V - used in power sequencing, debounce circuits, and basic digital state-holding applications.

For engineers reviewing the CD4013BMG4 datasheet, CD4013BMG4 pinout, CD4013BMG4 application, or CD4013BMG4 equivalent, this page delivers verified functional specifications, validated pin roles, confirmed SOIC-14 package mapping, real-world use cases, and two technically documented alternative parts for design-in flexibility.

Technical Context

The CD4013BMG4 implements two identical, electrically isolated D-type flip-flops, each triggered on the positive-going edge of its dedicated clock input. Set and reset are asynchronous, active-high, and override clock/data behavior - enabling immediate state control without clock dependency.

It operates across –55°C to +125°C with static CMOS inputs (≤1 µA max input current at 18 V), symmetrical output drive (±6.8 mA sink/source at 15 V), and guaranteed noise margins of 2.5 V at 15 V supply - making it suitable for noisy industrial and automotive environments where rail-to-rail logic compatibility and latch-up immunity are critical.

Key Specifications

Pinout & Package

CD4013BMG4 is housed in a 14-pin SOIC (D) package measuring 8.65 mm × 3.90 mm, with standard JEDEC MS-012AC footprint and RoHS-compliant NiPdAu lead finish. Pin 7 is VSS (ground), pin 14 is VDD (supply), and all inputs include integrated CMOS protection networks.

FAQ

What is the maximum clock frequency supported by CD4013BMG4 at 5 V supply?

The CD4013BMG4 supports a maximum clock input frequency of 7 MHz (typical) at VDD = 5 V, with minimum pulse width of 70 ns. This is specified under Recommended Operating Conditions in the official TI datasheet SCHS023E, and verified across temperature ranges from –55°C to +125°C. The CD4013BMG4 maintains reliable toggle operation at this rate with proper load capacitance (≤50 pF) and input rise/fall times.

Does CD4013BMG4 support asynchronous reset functionality?

Yes, CD4013BMG4 provides fully asynchronous, active-high reset inputs (pins 4 and 10) that force Q = 0 and Q = 1 immediately - independent of clock or data states. This behavior is confirmed in the Function Table (Table 1) and Functional Description sections of the TI datasheet. No clock edge is required, and reset takes effect within the device's propagation delay (≤400 ns max at 5 V).

What package type and dimensions does CD4013BMG4 use?

CD4013BMG4 uses a 14-pin SOIC (D) package with nominal body size 8.65 mm × 3.90 mm and standard JEDEC MS-012AC footprint. This is explicitly listed in TI's Packaging Information table and Orderable Addendum, where CD4013BMG4 is designated as "SOIC (D) | 14". The package features NiPdAu lead finish and meets Level-1 moisture sensitivity per J-STD-020.

Can CD4013BMG4 operate reliably at 15 V supply?

Yes, CD4013BMG4 is fully rated for 15 V operation - with guaranteed parameters including 24 MHz max clock frequency (typ), 6.8 mA output drive, and 2.5 V noise margin. All Electrical Characteristics tables (Sections 6.5–6.6) include explicit test conditions at VDD = 15 V, and Absolute Maximum Ratings permit up to 20 V DC. Operation at 15 V is routinely validated in industrial power-control reference designs.

How are unused inputs handled on CD4013BMG4?

Unused inputs on CD4013BMG4 - such as SET, RESET, or D pins of an unneeded flip-flop - must be tied to VDD or VSS to prevent floating. TI's Layout Guidelines (Section 10.1) mandate this to avoid undefined logic states and increased power consumption. For example, unused SET/RESET lines should be pulled low (to VSS) to disable them; unused D inputs may be tied to VDD or VSS depending on desired default state.
