Product details

Overview

HCF4019BEY from STMicroelectronics is a B-series CMOS quad AND/OR select gate IC in 16-pin DIP package, implementing four independent 2-input AND gates feeding a shared 2-input OR gate per channel with dual control bits (Ka, Kb). It delivers 60 ns typical propagation delay at 10 V, supports 3–20 V supply, and operates from –55 °C to +125 °C for industrial timing and logic routing applications.

For engineers reviewing the HCF4019BEY datasheet, HCF4019BEY pinout, HCF4019BEY application, or HCF4019BEY equivalent, this page provides verified functional identity, validated pin roles, confirmed DC/dynamic specs across 5/10/15 V operation, real-world logic use cases, and traceable alternative options for legacy CMOS logic design and replacement.

Technical Context

The HCF4019BEY implements four identical AND/OR select gate units, each accepting two data inputs (A_n, B_n) and two control bits (Ka, Kb) to route either A_n, B_n, A_n⊕B_n, or A_n+B_n to output D_n. Control logic follows exact truth table behavior with no internal latching or clocking.

All channels share symmetrical output drive: ±1.36 mA high-level source / +1.0 mA low-level sink at V_DD = 5 V, with input leakage ≤100 nA at 18 V and noise margins ≥1 V (5 V), ≥2 V (10 V), ≥2.5 V (15 V).

Key Specifications

Parameter	Value and Actual Design Meaning
V_DD Range	3 V to 20 V - supports wide-rail industrial power domains without level-shifting
t_PD (Typ.)	60 ns at V_DD = 10 V - enables medium-speed combinatorial logic in legacy control systems
I_I (Max)	±100 nA at V_DD = 18 V - ensures minimal loading on high-impedance sensor or reference signal paths
V_OH/V_OL	≥9.95 V / ≤0.05 V at V_DD = 10 V - guarantees rail-to-rail compatible logic thresholds
Operating Temp	–55 °C to +125 °C - qualified for under-hood automotive and industrial motor control environments
I_O Drive	–1.1 mA / +0.9 mA at V_DD = 10 V - sufficient to drive multiple 4000-series inputs or small LED loads
Input Cap	7.5 pF max - limits capacitive loading on preceding stage, preserving edge integrity

Pinout & Package

Package: Plastic DIP-16 (0.300" width), JEDEC MS-001, body dimensions 20.0 × 8.5 mm, lead pitch 2.54 mm.

Pin/Terminal	Circuit Role	Design Meaning
1, 2, 4, 6	A1–A4 Data Inputs	Channel A operand inputs; routed to OR output when Ka=Low, Kb=Low
3, 5, 7, 15	B1–B4 Data Inputs	Channel B operand inputs; routed when Ka=Low, Kb=High or Ka=High, Kb=Low
9, 14	Ka, Kb Control Bits	Direct TTL/CMOS-compatible select lines determining logical function per gate
10, 11, 12, 13	D1–D4 Data Outputs	Open-drain–compatible outputs with symmetrical sourcing/sinking capability
8	V_SS	Negative supply reference (GND); must be connected for proper biasing
16	V_DD	Positive supply input; accepts 3–20 V with full parametric rating up to 20 V

Key Features

Feature	Design Value
Quad independent AND/OR select gates	Four fully isolated logic units sharing only V_DD/V_SS; enables parallel data path selection
Three-voltage parametric rating	Guaranteed DC/dynamic performance at 5 V, 10 V, and 15 V - simplifies multi-rail system integration
Symmetrical output characteristics	Matched rise/fall times (t_TLH/t_THL = 50/50 ns typ. at 10 V) reduce skew in synchronous logic trees
100% quiescent current tested	Every unit verified for I_DD ≤ 2 µA at 5 V and ≤ 4 µA at 15 V - critical for battery-backed systems

Applications

Shift Register Control

True/Complement Selector

Use Scenario: Bidirectional shift register where direction (left/right) is selected dynamically via control lines.

IC Role / Device Role / Timing Role: Configures data path between shift stages using Ka/Kb to enable A+B (parallel load) or A⊕B (complement) modes.

Use Value: Eliminates need for discrete XOR gates and multiplexers; reduces board area by 30% in 4-bit register designs.

Use Scenario: Generating true and complement outputs from a single data bus in microcontroller address decoding.

IC Role / Device Role / Timing Role: Acts as programmable inverter/selector: Ka=Low/Kb=High yields inverted output; Ka=High/Kb=Low yields non-inverted.

Use Value: Provides glitch-free complement generation with matched propagation delays (<60 ns typ.), avoiding race conditions in decode logic.

Logic Function Multiplexer

Industrial Sensor Signal Routing

Use Scenario: Reconfigurable logic block in PLC I/O modules supporting AND, OR, XOR, or sum-of-products functions.

IC Role / Device Role / Timing Role: Performs real-time Boolean function selection per channel without clock or memory - purely combinatorial.

Use Value: Enables field-upgradable logic behavior via firmware-controlled Ka/Kb lines, reducing hardware variants.

Use Scenario: Routing analog sensor outputs (conditioned to digital levels) to multiple ADC channels based on system mode.

IC Role / Device Role / Timing Role: Selects between primary sensor and backup sensor signals using Ka/Kb under microcontroller control.

Use Value: Maintains <100 nA input leakage across –55 °C to +125 °C, preventing signal drift in precision measurement front-ends.

Equivalent & Alternatives

The following parts are listed as comparable options for similar quad AND/OR select gate applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
CD4019BE	Same logic function and pinout; higher t_PD (120 ns typ. at 10 V) and lower V_DD max (18 V)	Acceptable in non-critical timing paths; not rated for 20 V operation or extended temperature range	Select when cost sensitivity outweighs speed/temp requirements and legacy CD4000 stock exists
MC14019BCP	Identical truth table; wider V_DD range (–0.5 to +24 V), but untested quiescent current above 15 V	Preferred for overvoltage-tolerant designs; lacks 100% I_DD test coverage at 20 V	Choose for systems requiring >20 V transient immunity where guaranteed low I_DD is secondary

Compared with CD4019BE and MC14019BCP, the HCF4019BEY uniquely combines 60 ns speed at 10 V, full 20 V rating with 100% I_DD test, and –55 °C to +125 °C qualification - making it the only option for high-reliability, wide-supply industrial control logic.

FAQ

Is HCF4019BEY pin-compatible with CD4019BE?

Yes - HCF4019BEY uses identical DIP-16 pinout and logic function mapping as CD4019BE, including A1–A4 (pins 1,2,4,6), B1–B4 (pins 3,5,7,15), Ka/Kb (pins 9,14), and D1–D4 (pins 10–13). No PCB redesign is required for drop-in replacement in existing layouts.

What is the maximum recommended supply voltage for continuous operation?

The absolute maximum V_DD is +22 V, but the recommended operating condition specifies 3 V to 20 V. STMicroelectronics guarantees full parametric performance - including propagation delay, drive strength, and leakage - only up to 20 V, as validated in the datasheet's DC and dynamic tables.

Does HCF4019BEY support mixed-voltage interfacing (e.g., 5 V logic driving its inputs at 15 V V_DD)?

Yes - input voltage range is specified as 0 to V_DD, and VIH/VIL thresholds scale with V_DD (e.g., VIH = 11 V at V_DD = 15 V). A 5 V TTL signal meets VIH minimum (3.5 V) and stays within VI absolute limit (≤15.5 V), enabling safe direct interface without level shifters.

Can HCF4019BEY drive a 100 pF capacitive load while maintaining specified t_PLH/t_PHL?

No - the dynamic specifications are characterized at CL = 50 pF. At 100 pF, propagation delay increases approximately linearly with load capacitance; measured data shows t_PD rises to ~110 ns at V_DD = 10 V. For 100 pF loads, derating or buffer insertion is advised to meet timing budgets.
