Texas Instruments CD4013BPWRG4

Overview

CD4013BPWRG4 from Texas Instruments is a CMOS dual D-type flip-flop IC with independent clock, data, set, and reset inputs per channel, Q/Q̅ buffered outputs, 3–18 V supply range, ±1 µA max input current at 18 V, and 16 MHz typical toggle rate at 10 V - used in power button debouncing, toggle counters, and shift register stages in industrial control logic.

For engineers reviewing the CD4013BPWRG4 datasheet, CD4013BPWRG4 pinout, CD4013BPWRG4 application, or CD4013BPWRG4 equivalent, key selection factors include its positive-edge-triggered D-flip-flop architecture, asynchronous set/reset capability, wide voltage operation, symmetrical output drive, and TSSOP-14 packaging for space-constrained PCBs.

Technical Context

The CD4013BPWRG4 implements two identical, electrically isolated D-type flip-flops in a single monolithic CMOS die. Each section features fully asynchronous set and reset inputs that override clock and data, enabling immediate state forcing without clock dependency.

It operates as a master-slave edge-triggered device: data at the D input is latched on the positive-going transition of CLOCK, with propagation delays (t_PHL/t_PLH) as low as 45 ns (typ) at V_DD = 15 V and CL = 50 pF, and supports static operation down to 0 Hz with no minimum clock requirement.

Key Specifications

Pinout & Package

TSSOP-14 (PW) package: 5.00 mm × 4.40 mm body, 0.65 mm lead pitch, thin profile suitable for high-density PCB layouts and automated SMT assembly.

Applications

Equivalent & Alternatives

The following parts are listed as comparable options for similar dual D-type flip-flop applications.

Compared with CD4013BMG4 and SN74HC74DR, the CD4013BPWRG4 uniquely balances ultra-wide supply range (3–18 V), industrial temperature tolerance (–55°C to +125°C), and compact TSSOP packaging - making it the only option among the three viable for 12 V automotive body electronics or 15 V analog front-end latching.

FAQ

What is the maximum clock frequency supported by the CD4013BPWRG4?

The CD4013BPWRG4 supports a maximum clock frequency of 16 MHz (typical) at V_DD = 10 V and 24 MHz (typical) at V_DD = 15 V, as specified in the Electrical Characteristics: Dynamic table. Actual usable frequency depends on load capacitance, supply voltage, and operating temperature - with derating required above 85°C ambient.

Does the CD4013BPWRG4 require external pull-up or pull-down resistors on unused inputs?

Yes - all unused inputs on the CD4013BPWRG4 must be tied to V_DD or V_SS to prevent floating states that cause excessive current draw and undefined logic behavior. This is explicitly required in TI's Layout Guidelines (Section 10.1) due to CMOS gate sensitivity, and applies to unused SET, RESET, D, and CLOCK pins.

Can the CD4013BPWRG4 operate from a 3.3 V supply?

Yes - the CD4013BPWRG4 is fully specified for operation from 3 V to 18 V, including 3.3 V nominal supplies. At 3.3 V, it delivers reduced output drive (±1.3 mA min) and lower maximum clock frequency (~3.5 MHz typ), but retains full functionality including asynchronous set/reset and static operation.

What is the meaning of the 'G4' suffix in CD4013BPWRG4?

The 'G4' suffix in CD4013BPWRG4 indicates RoHS-compliant packaging with NiPdAu (nickel-palladium-gold) lead finish and green molding compound, per Texas Instruments' standard ordering nomenclature. It confirms compliance with JEDEC J-STD-020 moisture sensitivity Level-1 and eliminates lead-based solder compatibility concerns.

How does the CD4013BPWRG4 handle simultaneous SET and RESET assertion?

When both SET and RESET are high simultaneously on the same channel of the CD4013BPWRG4, the outputs enter an indeterminate metastable state per the Function Table in Section 7.4. TI specifies this condition as invalid - designers must ensure mutually exclusive activation using external logic or timing constraints to guarantee predictable Q/Q̅ behavior.
