Texas Instruments CD4013BPW

Overview

CD4013BPW from Texas Instruments is a CMOS dual D-type flip-flop in a 14-pin TSSOP package, operating from 3 V to 18 V supply, with asynchronous set/reset, positive-edge clock triggering, and independent Q/Q̅ outputs per section. It delivers 16 MHz typical toggle rate at 10 V and supports shift register, counter, and toggle applications in industrial control and power management systems.

For engineers reviewing the CD4013BPW datasheet, CD4013BPW pinout, CD4013BPW application, or CD4013BPW equivalent, this device serves as a low-power, wide-voltage-range storage element for synchronous logic design, timing control, and state-holding functions where rail-to-rail input compatibility and ESD-robust CMOS inputs are required.

Technical Context

The CD4013BPW implements two electrically isolated D-type latches, each with fully independent data (D), clock (CLK), set (SET), reset (RESET), Q, and Q̅ terminals. Its static CMOS architecture ensures ultra-low quiescent current (≤0.02 µA at 25°C, VDD = 5 V) and high noise immunity (2.5 V at 15 V supply).

It operates across –55°C to +125°C, features symmetrical output drive (±6.8 mA at VDD = 15 V), and uses standard TTL-compatible input thresholds (VIH = 11 V, VIL = 4 V at VDD = 15 V). Propagation delays are voltage-dependent: tPHL/tPLH = 45–90 ns (typ) at VDD = 15 V, CL = 50 pF.

FAQ

What is the maximum clock frequency supported by the CD4013BPW?

The CD4013BPW supports up to 16 MHz typical clock toggle rate at VDD = 10 V, and 24 MHz maximum at VDD = 15 V per the datasheet's dynamic specifications. Actual achievable frequency depends on load capacitance, supply voltage stability, and PCB layout - for reliable operation at >10 MHz, keep CL ≤ 50 pF and use tight clock routing with local decoupling.

Does the CD4013BPW support 3.3 V logic levels?

Yes, the CD4013BPW operates down to 3 V supply and accepts 3.3 V logic inputs as valid high-level signals (VIHmin = 3.5 V at VDD = 5 V, scaling proportionally). At VDD = 3.3 V, VIHmin ≈ 2.3 V - ensuring full compatibility with standard 3.3 V CMOS outputs without level translation.

How should unused SET and RESET pins be handled on the CD4013BPW?

Unused SET and RESET pins on the CD4013BPW must be tied to VSS (ground) to prevent floating inputs, which can cause undefined output states or increased power consumption. TI explicitly warns against leaving CMOS inputs unconnected - use 10 kΩ pull-down resistors or direct connection depending on noise environment.

Is the CD4013BPW pin-compatible with other CD4013 variants?

Yes, the CD4013BPW shares identical pinout and functionality with all CD4013B variants (e.g., CD4013BE, CD4013BM, CD4013BNSR), differing only in package type (TSSOP vs PDIP/SOIC/SOP). Electrical behavior, timing, and absolute maximum ratings are fully aligned across the family.

What is the thermal resistance (RθJA) of the CD4013BPW package?

The CD4013BPW in TSSOP-14 has a junction-to-ambient thermal resistance (RθJA) of 121°C/W, as specified in TI's thermal metrics table. This value assumes standard JEDEC 2-layer board conditions; actual performance improves with copper pour, thermal vias, and airflow - critical for continuous operation above 85°C ambient.
