Product details
Overview
74VHCT08BQ,115 from Nexperia is a quad 2-input AND gate IC in DHVQFN14 package, operating at 4.5–5.5 V supply with TTL-compatible input thresholds (VIH = 2.0 V min, VIL = 0.8 V max), 7.9 ns typical propagation delay (CL = 50 pF), and rated for -40 °C to +125 °C ambient operation. It serves as a logic-level combinatorial gate in digital control signal routing, bus arbitration, and enable logic for industrial microcontroller peripherals.
For engineers reviewing the 74VHCT08BQ,115 datasheet, 74VHCT08BQ,115 pinout, 74VHCT08BQ,115 application, or 74VHCT08BQ,115 equivalent, key selection criteria include TTL-level input compatibility, thermal-enhanced QFN packaging for high-density PCBs, guaranteed operation up to +125 °C, and low dynamic power dissipation (CPD = 12.0 pF) in 5 V systems.
Technical Context
This device implements four independent 2-input AND gates using high-speed Si-gate CMOS technology compliant with JEDEC JESD7-A. Its TTL-compatible input stage accepts standard 5 V logic levels while driving CMOS loads, enabling seamless interfacing between legacy TTL and modern low-power logic subsystems.
The DHVQFN14 package (SOT762-1) features an exposed thermal pad (non-electrical, optional GND connection), 2.5 × 3 mm body, 0.85 mm height, and 14 terminals arranged in quad-flat configuration-optimized for thermal performance and board space efficiency in compact embedded controllers.

Applications
| Industrial PLC I/O Expansion | Microcontroller Peripheral Enable Logic |
|---|---|
Use Scenario: Adding discrete digital I/O modules to programmable logic controllers where space and thermal density are constrained. IC Role / Device Role / Timing Role: Quad AND gate performs channel-by-channel enable masking for 8-bit parallel I/O ports, synchronizing with CPU address strobes. Use Value: DHVQFN14 footprint saves >40% board area vs SO14; +125 °C rating eliminates need for derating in enclosed cabinets. | Use Scenario: Managing peripheral activation (ADC, UART, SPI) in resource-constrained Cortex-M0+ designs. IC Role / Device Role / Timing Role: Gates peripheral clock enables based on software-configured power states and bus arbitration signals. Use Value: TTL-compatible inputs eliminate external level shifters; 7.9 ns delay ensures setup/hold compliance with 50 MHz APB bus timing. |
| Automotive Body Control Module | Industrial Sensor Interface Aggregation |
Use Scenario: Implementing door lock actuation logic with redundant safety interlocks in non-safety-critical BCM subsystems. IC Role / Device Role / Timing Role: Combines door position sensor, key fob signal, and ignition status to generate validated lock/unlock command pulses. Use Value: -40 °C to +125 °C qualification matches under-dash thermal profile; HBM > 2000 V withstands ESD events during service access. | Use Scenario: Consolidating fault flags from multiple analog sensors (temperature, pressure, current) into a single diagnostic bus line. IC Role / Device Role / Timing Role: Performs OR-of-AND logic to detect simultaneous over-range conditions across sensor channels. Use Value: Balanced propagation delays ensure synchronized flag assertion; low ICC (< 40 μA) minimizes quiescent current in always-on monitoring circuits. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar quad 2-input AND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC08APWR | 3.3 V only (1.65–3.6 V), LVCMOS inputs, 3.7 ns tpd (CL = 50 pF) | Requires level translation when interfacing with 5 V TTL systems | Select for new 3.3 V-only designs prioritizing speed and lower voltage operation |
| 74HC08D,653 | CMOS inputs (VIH = 3.85 V @ VCC = 5.5 V), 11 ns tpd (CL = 50 pF), SO14 package | Lacks TTL-level input compatibility; larger SO14 footprint increases board area | Select when strict CMOS input thresholds are acceptable and thermal constraints are less severe |
Compared with SN74LVC08APWR and 74HC08D,653, the 74VHCT08BQ,115 uniquely bridges 5 V TTL and CMOS domains without level shifters, fits high-density layouts via DHVQFN14, and sustains full-speed operation across extended industrial temperatures-making it optimal for mixed-voltage legacy upgrades and thermally constrained edge nodes.

FAQ
What is the maximum allowable supply voltage for 74VHCT08BQ,115?
The absolute maximum supply voltage (VCC) is +7.0 V, but the recommended operating range is strictly 4.5 V to 5.5 V per JEDEC JESD7-A compliance. Operation above 5.5 V voids parametric guarantees and risks permanent damage due to oxide stress, even if within the 7.0 V absolute limit.
Can 74VHCT08BQ,115 operate reliably at 3.3 V supply?
No-74VHCT08BQ,115 is specified only for 4.5–5.5 V operation. At 3.3 V, VIH minimum (2.0 V) remains valid, but VOH drops below TTL HIGH threshold (≥ 2.4 V), causing output logic level violations. Use 74LVC08 for 3.3 V systems.
Is the exposed thermal pad on the DHVQFN14 package electrically connected?
No-the thermal pad (terminal 1 index area) has no electrical function. Per datasheet note, it may remain floating or be connected to GND, but must not be tied to VCC or any signal net. Soldering it to GND improves thermal resistance by ~15 °C/W but introduces no electrical coupling.
How does the 74VHCT08BQ,115 differ from the 74VHC08BQ variant?
The 74VHCT08BQ uses TTL-compatible input thresholds (VIH = 2.0 V, VIL = 0.8 V), while 74VHC08BQ uses CMOS thresholds (VIH = 3.85 V @ VCC = 5.5 V). This makes the VHCT version interoperable with legacy 5 V TTL outputs without level shifters, whereas VHC requires matched CMOS drivers.
