Product details

Overview

HEF4070BT-Q100 from Nexperia is a quad 2-input CMOS EXCLUSIVE-OR gate qualified to AEC-Q100 Grade 3, operating from -40 °C to +85 °C with supply voltage support up to 15 V, 5 V/10 V/15 V parametric ratings, and symmetrical output drive (±3.6 mA at VDD = 15 V). It serves as a logic-level comparator or parity generator in automotive body control modules.

For engineers reviewing the HEF4070BT-Q100 datasheet, HEF4070BT-Q100 pinout, HEF4070BT-Q100 application, or HEF4070BT-Q100 equivalent, key selection criteria include automotive qualification grade, input clamping diode integration for overvoltage-tolerant interfacing, propagation delay scalability across VDD (30–175 ns), and SO14 package compatibility with legacy 4000-series PCB footprints.

Technical Context

This device implements four independent XOR gates using standard CMOS process technology, each with fully static operation and no minimum clock or refresh requirement. Inputs feature integrated clamp diodes enabling direct interface to signals exceeding VDD when used with current-limiting resistors.

It complies with JEDEC JESD13-B and supports dynamic power calculation via vendor-provided formulas (e.g., PD = 14400 × fi + Σ(fo × CL) × VDD² at 15 V), with propagation delays defined per VDD and load capacitance (CL), and transition times specified down to 20 ns.

Key Specifications

Applications

Logical Comparator

Parity Generator

Use Scenario: Detecting mismatch between two 4-bit data buses in an automotive gateway ECU.

IC Role / Device Role / Timing Role: Each XOR gate compares one bit pair; outputs fed to OR tree for error flag generation.

Use Value: Enables real-time bus integrity checking with sub-55 ns per-bit latency at 15 V supply.

Use Scenario: Generating odd parity bits for CAN message transmission in ADAS sensor nodes.

IC Role / Device Role / Timing Role: Four XOR gates compute cumulative parity across 4-bit segments before serial encoding.

Use Value: Delivers deterministic, zero-latency parity logic without external timing constraints or clocks.

Signal Inversion Control

Binary Adder Carry Logic

Use Scenario: Selectively inverting sensor signal polarity in a programmable HVAC control module.

IC Role / Device Role / Timing Role: One XOR gate acts as controlled inverter: input A = signal, input B = mode select (0 = pass, 1 = invert).

Use Value: Provides glitch-free polarity switching with no additional control logic or propagation delay variation.

Use Scenario: Implementing half-adder carry-out function in a redundant microcontroller watchdog timer.

IC Role / Device Role / Timing Role: XOR gate computes sum bit; combined with AND/OR logic for full adder functionality.

Use Value: Supports fail-safe arithmetic verification using discrete logic, independent of MCU ALU.

Equivalent & Alternatives

The following parts are listed as comparable options for similar XOR gate applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
CD4070BME4	Non-automotive; no AEC-Q100 qualification; wider temp range (-55 °C to +125 °C) but unqualified for automotive use	Not approved for production automotive systems requiring Q100 compliance	Select only for industrial or prototype environments where automotive qualification is not mandated
SN74HC86DR	Higher speed (tPD ≈ 15 ns at 5 V), lower VDD range (2–6 V), no input clamp diodes, HBM ESD = 2000 V	Lacks overvoltage-tolerant inputs; unsuitable for mixed-voltage node interfacing without level shifters	Prefer for high-speed 5 V-only designs where input clamping is unnecessary and faster timing is critical

Compared with CD4070BME4 and SN74HC86DR, HEF4070BT-Q100 uniquely combines AEC-Q100 Grade 3 certification, integrated input clamp diodes for mixed-rail interfacing, and scalable 3–15 V operation-making it the only choice for production automotive logic where reliability, voltage flexibility, and overvoltage resilience are jointly required.

FAQ

Is HEF4070BT-Q100 compatible with 5 V TTL logic levels?

No, HEF4070BT-Q100 is a CMOS device with V_IH = 11.0 V at V_DD = 15 V and V_IL = 4.0 V - it does not meet TTL input thresholds (2.0 V/0.8 V). Direct interface requires level translation or pull-up/pull-down networks to ensure valid HIGH/LOW recognition.

Can HEF4070BT-Q100 drive a 100 pF capacitive load reliably?

Yes - at V_DD = 15 V, t_PHL/t_PLH increases to ~55 ns (max) and t_t to ~40 ns (max) for C_L = 100 pF, remaining within specification. Total power dissipation remains below 500 mW if output frequency and load count are managed per the dynamic power formula.

What is the maximum continuous output current per pin?

The absolute maximum output clamping current is ±10 mA (per IEC 60134), but recommended steady-state drive is limited to ±3.6 mA at V_DD = 15 V (I_OH/I_OL min/max values in Table 6), ensuring VOL ≤ 0.05 V and VOH ≥ 14.95 V under load.

Does HEF4070BT-Q100 require external decoupling capacitors?

Yes - a 100 nF ceramic capacitor placed as close as possible to pins 7 (VSS) and 14 (VDD) is required to suppress switching noise and maintain stable supply during simultaneous output transitions, especially at higher VDD and load capacitance.
