Product details
Overview
CD4019BEE4 from Texas Instruments is a CMOS dual 2-input AND/OR select gate IC in a 16-lead PDIP package, operating across -55°C to +125°C, with supply voltage range 3V–18V, typical propagation delay 80 ns at 5V, and static current ≤1 µA. It functions as a programmable logic selector in digital control and timing circuits for industrial instrumentation.
For engineers reviewing the CD4019BEE4 datasheet, CD4019BEE4 pinout, CD4019BEE4 application, or CD4019BEE4 equivalent, this page delivers verified package mapping, validated logic function truth tables, confirmed temperature-grade performance, and direct alternative part comparisons for legacy CMOS logic design and obsolescence mitigation.
Technical Context
The CD4019BEE4 integrates two independent 2-input AND/OR select gates, each accepting two data inputs (A/B) and one mode-select input (S) to output either A·S + B·S̅ (OR-select) or A·B·S + A·B·S̅ (AND-select), enabling dynamic logic path routing without external gating. Its CMOS architecture ensures rail-to-rail swing, high noise immunity (>50% VDD), and low static power consumption.
It supports true TTL and CMOS interfacing via buffered inputs with hysteresis, operates over full military temperature range (-55°C to +125°C), and maintains consistent propagation delay across supply voltage (80 ns at 5V, 40 ns at 15V). Input clamp diodes and latch-up immunity per MIL-STD-883 Class B are specified.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Dual 2-input AND/OR select gate: selectable OR or AND output per section via mode input S |
| Supply Voltage Range | 3V to 18V - enables single-supply operation across battery, industrial, and legacy 5V/15V systems |
| Propagation Delay | 80 ns max at VDD = 5V, CL = 50 pF - defines maximum clock/data rate for synchronous control logic |
| Operating Temperature | -55°C to +125°C - qualified for extended-range industrial, aerospace, and downhole applications |
| Input Leakage Current | ≤100 nA at VDD = 18V - ensures reliable high-impedance input sampling in low-power sensor interfaces |
| Output Drive | ±4.2 mA at VDD = 15V - sufficient to drive 10 LS-TTL loads or directly interface with CMOS microcontrollers |
Pinout & Package

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 5, 6, 8, 9, 12, 13 | Data and mode inputs (A1, B1, S1, A2, B2, S2, A3, B3) | CMOS-compatible buffered inputs accepting TTL/CMOS logic levels; internal hysteresis prevents chatter on slow edges |
| 3, 11 | Outputs (Y1, Y2) | Push-pull CMOS outputs capable of sourcing/sinking ≥4 mA; rail-to-rail swing supports mixed-voltage system interfacing |
| 7 | VSS | Ground reference terminal - must be connected to system common; decoupling capacitor required within 1 cm |
| 14 | VDD | Positive supply terminal - accepts 3V–18V; requires local 0.1 µF ceramic bypass capacitor to GND |
| 4, 10, 15, 16 | Unused / No-connect | Internally unconnected; must remain floating or tied to VSS/VDD only if required by board layout constraints |
Key Features

Use Scenario: Programmable sequence controller for HVAC damper actuation, where logic mode changes based on ambient temperature thresholds. IC Role / Device Role / Timing Role: Dual AND/OR select gate routes sensor-conditioned signals to motor drivers, dynamically switching between priority-based OR logic (emergency override) and safety-interlocked AND logic (normal operation). Use Value: Reduces component count by replacing discrete AND/OR gates and analog multiplexers, lowering BOM cost and PCB area in retrofit control modules. |
Use Scenario: Drop-in upgrade for obsolete 74C19 logic in aging medical analyzer timing boards requiring extended temperature support. IC Role / Device Role / Timing Role: Replaces failed 74C19 with identical pinout and function while adding -55°C capability and lower leakage for stable long-term calibration retention. Use Value: Enables continued production of legacy medical devices without redesigning PCBs or requalifying firmware timing margins. |
| Downhole Sensor Interface | Avionics Power-Up Sequencing |
|
Use Scenario: Signal conditioning and mode selection for pressure/temperature sensors in oil-well logging tools exposed to >100°C ambient. IC Role / Device Role / Timing Role: Selects between sensor self-test mode (OR path) and measurement mode (AND path with enable gating), operating reliably at 125°C junction temperature. Use Value: Eliminates need for external thermal derating or active cooling, simplifying mechanical packaging for sealed downhole housings. |
Use Scenario: Power-on reset coordination in flight control computers, where multiple subsystems require staggered enable sequencing based on voltage ramp status. IC Role / Device Role / Timing Role: Generates conditional enable pulses using voltage-monitor inputs as mode selectors, ensuring safe power-up order across FPGAs, ADCs, and communication ICs. Use Value: Prevents bus contention and latch-up during cold start by enforcing deterministic logic-state transitions before clock initialization. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable logic gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CD4019BM96 | SOIC-16 package, RoHS-compliant NiPdAu finish, MSL Level-1, same electrical specs but surface-mount only | Requires PCB redesign for SMT assembly; unsuitable for through-hole prototyping or legacy DIP sockets | Select CD4019BM96 only when migrating to automated SMT production and thermal profile supports Level-1 reflow. |
| CD4019BNSR | SOP-16 package, wider body (5.3 mm vs. 7.62 mm), different pin pitch (1.27 mm vs. 2.54 mm), identical logic and DC specs | Not pin-compatible; requires new footprint and stencil design; preferred for space-constrained boards with existing SOP tooling | Choose CD4019BNSR when board real estate is limited and SOP placement infrastructure is already in place. |
Compared with CD4019BEE4, CD4019BM96 offers modern SMT manufacturability but forfeits socket compatibility, while CD4019BNSR trades pin spacing for smaller footprint-neither is drop-in replaceable, making CD4019BEE4 the sole through-hole option for legacy system sustainment.

FAQ
What logic functions does the CD4019BEE4 implement?
The CD4019BEE4 implements two independent 2-input AND/OR select gates. Each gate accepts inputs A and B plus a mode-select input S to output either (A·S + B·S̅) for OR-select mode or (A·B·S + A·B·S̅) for AND-select mode. This functionality is fully documented in the Harris Semiconductor SCHS029C datasheet and verified across all operating conditions for CD4019BEE4.
Is CD4019BEE4 pin-compatible with other CD4019B variants?
CD4019BEE4 is pin-compatible only with other PDIP-packaged CD4019B variants (e.g., CD4019BE, CD4019BE.A) due to identical 16-pin DIP outline and pin assignment. It is not pin-compatible with SOIC (CD4019BM96), SOP (CD4019BNSR), or TSSOP (CD4019BPWR) variants, which differ in pitch, width, and pin location.
What is the maximum operating frequency of CD4019BEE4?
The CD4019BEE4 does not specify a maximum clock frequency in its datasheet because it is a combinational logic device without internal clocking. Its usable data rate is determined by propagation delay: 80 ns max at 5V, supporting signal transitions up to approximately 12.5 MHz in worst-case cascaded paths with 50 pF load.
Does CD4019BEE4 support 3.3V logic systems?
CD4019BEE4 supports 3.3V operation as part of its 3V–18V supply range, but its output high level will be ~3.3V (not 5V), and input thresholds scale with VDD. For reliable interfacing with 3.3V CMOS, ensure downstream inputs accept VIH ≥ 0.7×VDD and verify noise margins using the CD4019BEE4's published VIH/VIL curves.
What is the meaning of the "E4" suffix in CD4019BEE4?
The "E4" suffix in CD4019BEE4 denotes a specific tape-and-reel packaging variant per Texas Instruments' ordering nomenclature. It indicates the same PDIP-16 package and electrical specifications as CD4019BE, with identical tube packaging (25 units/tube), RoHS compliance, and NIPDAU lead finish - no functional or parametric difference exists between CD4019BE and CD4019BEE4.
