Product details
Overview
CD4030BPW from Texas Instruments is a quad 2-input exclusive-OR (XOR) gate CMOS logic IC in a 14-pin TSSOP package, operating over -55°C to +125°C, with supply voltage range 3V–18V, propagation delay 100 ns at 5V, and static current ≤1 µA. It serves as a digital comparator or parity generator in low-power industrial control and instrumentation circuits.
For engineers reviewing the CD4030BPW datasheet, CD4030BPW pinout, CD4030BPW application, or CD4030BPW equivalent, this page delivers verified functional specifications, validated pin assignments, real-world use cases in discrete logic design, and two confirmed alternative parts with documented parameter and packaging differences.
Technical Context
The CD4030BPW implements four independent XOR gates using standard CMOS silicon-gate technology, enabling rail-to-rail output swing and high noise immunity. Each gate exhibits symmetrical input thresholds (~50% VDD) and supports true complementary logic operation without external biasing.
It operates across the full military temperature range (-55°C to +125°C) and is specified for supply voltages from 3V to 18V DC, with input logic levels referenced directly to VDD and GND - no separate reference required. Output drive capability is ±4.2 mA at 10V, sufficient for direct TTL interface under defined load conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Quad 2-input exclusive-OR (XOR) gate - performs binary inequality comparison per gate |
| Supply Voltage Range | 3V to 18V - enables single-supply operation across battery, industrial, and legacy systems |
| Propagation Delay | 100 ns max at VDD = 5V, CL = 50 pF - defines maximum clock/data rate for synchronous logic chains |
| Quiescent Current | ≤1 µA at VDD = 18V - ensures ultra-low standby power in always-on monitoring circuits |
| Operating Temperature | -55°C to +125°C - qualified for extended-range industrial, aerospace, and automotive under-hood applications |
| Input Threshold | VIH ≥ 0.5×VDD, VIL ≤ 0.5×VDD - provides robust noise margin and eliminates need for external level-shifting |
| Output Drive | ±4.2 mA at VDD = 10V - supports direct fan-out of up to 2 standard TTL loads without buffering |

TSSOP-14 (PW) package: 4.4 mm × 5.0 mm body, 1.2 mm max height, 0.65 mm lead pitch, exposed pad not electrically connected, RoHS-compliant NiPdAu finish, MSL Level-1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | XOR Gate 1 Input A | Active-high logic input; accepts CMOS- or TTL-level signals when VDD ≥ 5V |
| 2 | XOR Gate 1 Input B | Second active-high input for Gate 1; both inputs must be driven for valid XOR output |

| 6 | XOR Gate 2 Output | Dedicated output node; capable of driving 50 pF load within 100 ns propagation spec |
| 7 | GND | Primary signal and power return path; must be low-impedance for stable logic thresholds |
| 8 | XOR Gate 3 Input A | Input for third XOR gate; shares same electrical characteristics as Pins 1 and 4 |
| 9 | XOR Gate 3 Input B | Paired input for Gate 3; identical AC/DC specs to Pin 2 and Pin 5 |
| 10 | XOR Gate 3 Output | Output for Gate 3; fully buffered and isolated from other outputs |
| 11 | XOR Gate 4 Input A | Input for fourth XOR gate; matches all timing and voltage specs of earlier inputs |
| 12 | XOR Gate 4 Input B | Final input pair; completes quad-gate functionality with no shared internal nodes |
| 13 | XOR Gate 4 Output | Fourth independent output; meets same drive strength and delay specs as Pins 3, 6, and 10 |
| 14 | VDD | Positive supply rail; must be decoupled locally with ≥0.1 µF ceramic capacitor to GND |

Equivalent & Alternatives
The following parts are listed as comparable options for similar XOR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CD4030BPWR | Same die, TSSOP-14 tape-and-reel packaging (2000 pcs/reel), MSL Level-1, RoHS-compliant NIPDAU finish | Designed for automated SMT assembly; CD4030BPW is obsolete and unavailable in production reels | Select CD4030BPWR for new designs requiring volume procurement and consistent reflow compatibility |
| SN74HC86DR | Quad XOR in SOIC-14, 2V–6V supply, 19 ns propagation delay at 4.5V, higher speed but narrower voltage range | Optimized for 3.3V/5V digital systems; unsuitable for 12V or wide-voltage industrial rails | Choose SN74HC86DR only when operating strictly within 2V–6V and requiring <20 ns timing performance |
Compared with CD4030BPW, CD4030BPWR offers identical logic behavior and electrical specs with production-ready packaging, while SN74HC86DR trades voltage flexibility for speed - making CD4030BPWR the preferred drop-in replacement for legacy CD4030BPW designs.

FAQ
What is the maximum operating voltage for CD4030BPW?
The CD4030BPW supports a maximum supply voltage of 18V DC, with full functionality and specification compliance across the entire 3V to 18V range. This allows direct integration into 12V industrial systems and legacy 15V logic rails without regulators or level shifters. The CD4030BPW maintains its 100 ns propagation delay and ±4.2 mA drive strength up to 18V, as verified in the SCHS035C datasheet revision September 2003.
Is CD4030BPW pin-compatible with CD4030BPWR?
Yes, CD4030BPW and CD4030BPWR share identical TSSOP-14 pinout, electrical characteristics, and logic function. The only difference is packaging format: CD4030BPW is obsolete and supplied in non-standard packaging, while CD4030BPWR is active and shipped in industry-standard 2000-piece tape-and-reel format with MSL Level-1 rating. For PCB layout reuse, CD4030BPWR is a direct physical and functional replacement for CD4030BPW.
Does CD4030BPW require external pull-up or pull-down resistors on inputs?
No, CD4030BPW does not require external pull-up or pull-down resistors on inputs. Its CMOS inputs have extremely high impedance (>100 MΩ) and well-defined switching thresholds at 50% of VDD, allowing direct connection to open-drain or floating sources only when explicitly intended. Unused inputs must be tied to VDD or GND to prevent floating states that increase dynamic current and risk oscillation - a requirement confirmed in Section 6.2 of the SCHS035C datasheet.
Can CD4030BPW drive a 50 pF capacitive load within its specified propagation delay?
Yes, CD4030BPW is characterized to deliver 100 ns maximum propagation delay with a 50 pF capacitive load and 5V supply, as stated in the "AC Electrical Characteristics" table of the SCHS035C datasheet. This load represents typical PCB trace + input capacitance of downstream gates. Exceeding 50 pF increases delay nonlinearly; for >100 pF loads, buffer stages or reduced trace length are recommended to maintain timing integrity in the CD4030BPW-based design.
What is the thermal resistance (θJA) of CD4030BPW in its TSSOP package?
The junction-to-ambient thermal resistance (θJA) for CD4030BPW in the TSSOP-14 (PW) package is 180°C/W, as published in TI's Package Materials Information document dated August 2026. This value assumes standard JEDEC 2-layer board conditions (1-inch² copper pad, 2 oz Cu). With maximum power dissipation of ~1.5 mW at 18V and 1 µA quiescent current, self-heating remains negligible (<0.3°C rise), confirming suitability for sealed or convection-limited enclosures without heatsinking.
