Product details
Overview
74HCT08D,653 from Nexperia is a quad 2-input AND gate IC with TTL-compatible input thresholds (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 4.5–5.5 V), SO14 package (SOT108-1), and guaranteed operation from −40 °C to +125 °C. It delivers 4.32 V VOH at −4.0 mA output load and 0.26 V VOL at 5.2 mA, with propagation delay of 14–36 ns across temperature and supply conditions.
For engineers reviewing the 74HCT08D,653 datasheet, 74HCT08D,653 pinout, 74HCT08D,653 application, or 74HCT08D,653 equivalent, this device serves as a standard logic-level combinatorial gate for digital control sequencing, bus enable logic, and synchronous signal gating in industrial microcontroller interfaces and power management subsystems.
Technical Context
The 74HCT08D,653 implements four independent AND gates using CMOS technology with TTL-level input voltage compatibility, enabling direct interfacing with legacy 5 V TTL outputs without level-shifting. Its inputs include clamp diodes for overvoltage tolerance when used with current-limiting resistors.
It operates across 4.5–5.5 V supply range, supports static drive capability up to ±4.0 mA (high-side) and ±5.2 mA (low-side), and maintains defined logic thresholds and timing performance over full industrial and extended automotive-grade temperature range (−40 °C to +125 °C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Quad 2-input AND gate - provides four independent Boolean AND operations per package |
| Supply Voltage Range | 4.5 V to 5.5 V - matches standard 5 V TTL/CMOS system rails with no external regulation required |
| Input Thresholds | VIH ≥ 2.0 V, VIL ≤ 0.8 V - ensures reliable recognition of TTL output levels (e.g., 74LS, 74F families) |
| Output Drive | VOH ≥ 3.98 V @ −4.0 mA, VOL ≤ 0.26 V @ 5.2 mA - sufficient to drive multiple 74HCT inputs or small capacitive loads |
| Propagation Delay | 14–36 ns (VCC = 4.5 V, CL = 50 pF) - enables use in sub-20 MHz synchronous logic paths |
| Operating Temperature | −40 °C to +125 °C - qualified for under-hood, motor control, and industrial PLC environments |
| ESD Rating | HBM > 2000 V, CDM > 1000 V - meets JEDEC JS-001/JS-002 Class 2/C3 for robust handling in assembly |
Pinout & Package
74HCT08D,653 uses the SO14 plastic small outline package (SOT108-1), 14-pin, 3.9 mm body width, with gull-wing leads and standard 1.27 mm pitch. Pin 1 is marked by a notch or index area on the package top edge.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A, 2A, 3A, 4A (Pins 1, 4, 9, 12) | Data input A for each gate | First input of AND gate n; accepts TTL-compatible logic levels |
| 1B, 2B, 3B, 4B (Pins 2, 5, 10, 13) | Data input B for each gate | Second input of AND gate n; clamped to prevent overvoltage damage |
| 1Y, 2Y, 3Y, 4Y (Pins 3, 6, 8, 11) | Data output for each gate | Active-high AND result; drives downstream CMOS/TTL loads directly |
| GND (Pin 7) | Ground reference | 0 V return path for all internal circuitry and I/O; must be low-impedance |
| VCC (Pin 14) | Positive supply | Primary 4.5–5.5 V power rail; decoupling capacitor recommended near pin |
Key Features
| Feature | Design Value |
|---|---|
| TTL-compatible inputs | Accepts standard 5 V TTL output voltages without level shifters or pull-ups |
| Wide temperature range | Specified from −40 °C to +125 °C - suitable for non-automotive high-reliability industrial use |
| Input clamp diodes | Enables safe interface to signals exceeding VCC when used with series current-limiting resistors |
| Low quiescent current | ICC ≤ 40 μA at VCC = 5.5 V and full temperature range - minimizes standby power |
| High noise immunity | Guaranteed 400 mV noise margin at VCC = 5 V - resists EMI in noisy industrial environments |
Applications
| Industrial PLC I/O Expansion | Microcontroller Bus Enable Logic |
|---|---|
|
Use Scenario: Enabling/disabling parallel data lines between a microcontroller and peripheral modules based on address decode. IC Role / Device Role / Timing Role: Quad AND gate acts as active-high bus gate, synchronizing data transfer only when both chip select and read/write strobe are asserted. Use Value: Eliminates need for discrete transistors or complex CPLD logic; reduces board space and BOM count while maintaining deterministic timing. |
Use Scenario: Controlling access to shared SPI or UART peripherals among multiple MCU cores in an embedded gateway. IC Role / Device Role / Timing Role: Performs logical arbitration of enable signals to prevent bus contention during simultaneous peripheral requests. Use Value: Provides glitch-free, race-free gating with sub-36 ns propagation - faster than software-based semaphore polling. |
| Power Sequencing Control | Digital Sensor Interface Conditioning |
|
Use Scenario: Generating delayed enable signals for DC-DC converters in multi-rail power systems where startup order must be enforced. IC Role / Device Role / Timing Role: Combines reset assertion and upstream supply OK signals to produce sequenced enable pulses for downstream regulators. Use Value: Replaces RC-delay networks with precise, temperature-stable logic-level control - improves startup repeatability across operating conditions. |
Use Scenario: Validating sensor data readiness before latching into an ADC controller, e.g., combining "data valid" and "conversion complete" flags. IC Role / Device Role / Timing Role: Synchronizes asynchronous sensor status signals to ensure only fully settled data triggers acquisition. Use Value: Prevents corrupted samples due to metastability or partial updates; eliminates need for FPGA-based synchronization logic. |
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 |
|---|---|---|---|
| SN74HCT08DR (Texas Instruments) | Same logic function, SO14 package, −40 °C to +85 °C rating; slightly higher ICC (max 40 μA vs. 40 μA) and identical VOH/VOL specs | Limited to commercial temperature range; not rated for +125 °C operation | Select when cost sensitivity outweighs extended temperature requirement and TI supply chain preference applies |
| 74HCT08PW,118 (Nexperia TSSOP14) | Identical electrical specs and temperature range, but in TSSOP14 (SOT402-1) package - 4.4 mm width, thinner profile, finer pitch (0.65 mm) | Requires rework of PCB layout; better thermal resistance and smaller footprint than SO14 | Select for space-constrained designs where automated assembly supports fine-pitch components |
Compared with SN74HCT08DR, the 74HCT08D,653 offers extended temperature qualification critical for industrial control; compared with 74HCT08PW,118, it provides easier manual soldering and legacy board compatibility at the cost of larger footprint and lower thermal efficiency.

FAQ
Can 74HCT08D,653 operate at 3.3 V supply?
No. The 74HCT08D,653 is specified only for 4.5 V to 5.5 V operation per its recommended conditions. At 3.3 V, input thresholds (VIH ≥ 2.0 V) may still be met, but VOH drops below TTL-compatible levels and timing parameters are not guaranteed. Use 74HC08 or 74LVC08 for 3.3 V systems.
Is pin 7 (GND) electrically connected to the exposed pad in SO14 package?
No. The SO14 (SOT108-1) package has no exposed thermal pad. Pin 7 is the sole GND connection via leadframe; no thermal pad or secondary grounding structure exists. Thermal dissipation relies on PCB copper area connected to pin 7.
What is the maximum capacitive load this device can drive reliably?
The 74HCT08D,653 is characterized with CL = 50 pF in dynamic testing. While it can drive heavier loads, propagation delay increases linearly with capacitance - at 100 pF, tpd degrades ~15–20% versus 50 pF. For loads > 75 pF, consider buffering or using higher-drive variants like 74HCT244.
Does this part support hot-swap or live-insertion?
No. The 74HCT08D,653 lacks hot-swap protection features such as power-up 3-state or Ioff. Applying VCC after signal inputs may cause latch-up or excessive current through input clamps. Always power VCC before applying input signals in system-level design.
