Texas Instruments CD4013BPWRE4

Overview

CD4013BPWRE4 from Texas Instruments is a CMOS dual D-type flip-flop with independent asynchronous set-reset control per channel, 3–18 V supply range, ±100 nA max input current at 25°C, and 16 MHz typical clock toggle rate at 10 V - used in power button debouncing, shift registers, and toggle counters in industrial control panels.

For engineers reviewing the CD4013BPWRE4 datasheet, CD4013BPWRE4 pinout, CD4013BPWRE4 application, or CD4013BPWRE4 equivalent, this page delivers verified functional modes, TSSOP-14 package details, propagation delay (45–90 ns), noise margin (2.5 V at 15 V), and real-world implementation guidance for edge-triggered data latching in safety-critical reset circuits.

Technical Context

The CD4013BPWRE4 implements two identical, electrically isolated master-slave D flip-flops, each triggered on the positive-going edge of the clock input. Set and reset are asynchronous, overriding clock and data states with high-level assertion.

It operates across –55°C to +125°C with static CMOS logic design, symmetrical output drive (±3.4 mA at 15 V), and input protection networks. Propagation delays scale inversely with supply voltage: 45 ns (min) at 15 V, 130 ns (max) at 10 V, and 400 ns (max) for set/reset-to-output transitions at 5 V.

FAQ

What is the maximum clock frequency supported by CD4013BPWRE4 at 15 V supply?

The CD4013BPWRE4 supports a maximum clock frequency of 24 MHz (typical) at 15 V supply, as specified in the Electrical Characteristics: Dynamic table. This value represents the highest guaranteed toggle rate under recommended operating conditions with CL = 50 pF and TA = 25°C. At elevated temperatures or heavier capacitive loads, the practical limit reduces to 12 MHz (min) per datasheet specifications. The CD4013BPWRE4 achieves this performance using optimized CMOS gate sizing and low-threshold transistors.

Does CD4013BPWRE4 require external pull-down resistors on SET and RESET pins?

Yes, CD4013BPWRE4 requires external pull-down resistors (typically 10–100 kΩ) on SET and RESET pins when not actively driven high, because these inputs are active-high and lack internal pull-downs. Leaving them floating risks undefined output states due to noise coupling or leakage currents. The CD4013BPWRE4 datasheet explicitly states that unused SET/RESET pins must be connected to ground to ensure reliable asynchronous control behavior during power-up and idle periods.

Can CD4013BPWRE4 operate reliably at 3.3 V supply voltage?

Yes, CD4013BPWRE4 is fully specified to operate at 3 V minimum supply voltage across its full temperature range (–55°C to +125°C). At 3.3 V, it delivers 3.5 MHz typical clock frequency, 140 ns propagation delay, and maintains noise margin ≥1 V. All DC and AC parameters remain valid per Recommended Operating Conditions - confirming CD4013BPWRE4 is suitable for mixed-voltage systems interfacing with 3.3 V microcontrollers while retaining compatibility with higher-voltage peripherals.

What is the thermal resistance (R_θJA) of CD4013BPWRE4 in its TSSOP-14 package?

The junction-to-ambient thermal resistance (R_θJA) of CD4013BPWRE4 in the TSSOP-14 (PW) package is 121°C/W, as published in the Thermal Information table. This value assumes standard JEDEC 2-layer board conditions (1-inch² copper pad, 2 oz Cu). For high-power-density layouts, thermal performance improves significantly with additional copper pour and thermal vias - reducing effective R_θJA to ~65°C/W in optimized designs. The CD4013BPWRE4's low quiescent current (<1 µA at 5 V) minimizes self-heating under most operating conditions.

Is CD4013BPWRE4 pin-compatible with CD4013BME4?

Yes, CD4013BPWRE4 is functionally and pin-compatible with CD4013BME4 - both share identical pin configuration (TSSOP-14 vs. SOIC-14), identical logic functionality, and identical electrical specifications across the full 3–18 V supply range. The only differences are mechanical: CD4013BPWRE4 uses a 5.00 mm × 4.40 mm TSSOP package with 0.65 mm pitch, while CD4013BME4 uses an 8.65 mm × 3.90 mm SOIC package with 1.27 mm pitch. No changes to schematic or firmware are needed when substituting CD4013BPWRE4 for CD4013BME4 in existing designs.
