Product details

Overview

74HC08S14-13 from Diodes Incorporated is a quad 2-input AND gate IC in SO-14 package, operating from 2.0V to 6.0V supply, delivering 4mA output drive at 4.5V, with Schmitt-trigger inputs and CMOS low-power logic. It implements Boolean Y = A • B across four independent channels for digital signal conditioning in timing-critical control paths.

For engineers reviewing the 74HC08S14-13 datasheet, 74HC08S14-13 pinout, 74HC08S14-13 application, or 74HC08S14-13 equivalent, key selection criteria include input threshold compatibility (VIH = 3.15V @ 4.5V), propagation delay (tPD = 9 ns typ @ 4.5V), output drive capability under load (VOL = 0.33V @ IOL = 4mA), and SO-14 thermal performance (TJ max = +150°C).

Technical Context

This device belongs to the 74HC high-speed CMOS logic family and implements four non-inverting AND functions with rail-to-rail input voltage tolerance (–0.5V to VCC + 0.5V) and guaranteed noise immunity via Schmitt-trigger action on all inputs. Each gate operates independently with no internal interconnects or shared resources.

It supports mixed-voltage system interfacing across 2.0–6.0V operation, features ESD protection exceeding 2kV HBM, and maintains consistent switching behavior over –40°C to +125°C ambient, with propagation delay variation ≤18 ns across temperature and voltage extremes.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage Range	2.0V to 6.0V - Enables direct interface with 3.3V and 5V logic domains without level shifters.
Output Drive (IOH/IOL)	±4mA @ VCC = 4.5V - Sufficient to drive one 74HC input or small capacitive loads (<50pF) without buffering.
Propagation Delay (tPD)	9 ns typical @ VCC = 4.5V, CL = 50pF - Supports >30 MHz toggle rates in synchronous logic chains.
Input Threshold (VIH/VIL)	VIH = 3.15V, VIL = 1.35V @ VCC = 4.5V - Ensures robust noise margin (>1.8V) against ground bounce or crosstalk.
Power Dissipation per Gate	20 pF Cpd @ 1 MHz - Predictable dynamic power consumption of ~12 μW/MHz/gate at 3.3V.
ESD Protection	2 kV HBM, 1 kV CDM - Meets industrial handling requirements without external protection circuitry.

Pinout & Package

74HC08S14-13 uses the standard SO-14 (Small Outline-14) surface-mount package with 1.27 mm pitch, 8.6 mm × 3.9 mm body, and 1.7 mm height. Pin 1 is marked by a notch or dot; pin numbering follows counter-clockwise convention from top-left corner when viewed from component side.

Pin/Terminal	Circuit Role	Design Meaning
1, 4, 9, 12	Input A (Gate 1–4)	Primary logic input for each AND gate; accepts TTL- or CMOS-compatible signals with Schmitt-trigger hysteresis.
2, 5, 10, 13	Input B (Gate 1–4)	Secondary logic input; paired with corresponding A input to generate Y = A • B output.
3, 6, 8, 11	Output Y (Gate 1–4)	Pull-up/pull-down capable push-pull output; drives downstream logic or small LEDs directly.
7	GND	Logic reference and return path for all gates; must be low-impedance to minimize ground bounce.
14	VCC	Positive supply rail; decoupling capacitor (100 nF) required within 5 mm for stable high-speed operation.

Key Features

Feature	Design Value
Schmitt-trigger inputs	Eliminates false triggering from slow-rising or noisy control signals (e.g., mechanical switch debouncing).
Wide supply range (2.0–6.0V)	Supports direct integration into both 3.3V microcontroller peripherals and legacy 5V bus systems.
CMOS low-power design	ICC < 40 μA max @ 6.0V - Enables use in battery-backed logic monitoring circuits with multi-year runtime.
SO-14 lead-free RoHS compliance	Fully compliant with EU Directive 2011/65/EU and halogen-free (<900 ppm Br+Cl), simplifying end-product environmental certification.

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
SN74HC08DR	TI part in SO-14; VIH = 3.15V @ 4.5V same, but tPD = 12 ns typ (slower by 3 ns); ICC = 40 μA max (same)	Valid for cost-sensitive industrial designs where 3 ns delay margin is acceptable	Select when TI supply chain preference or existing BOM alignment outweighs minor speed penalty
MC74HC08ADTR2G	ON Semiconductor TSSOP-14; identical logic function and thresholds, but 1.2 mm height vs SO-14's 1.7 mm; 15% smaller footprint	Better suited for space-constrained automotive ECUs requiring ultra-thin profile	Choose for PCB area optimization where thermal derating below 125°C is verified

Compared with SN74HC08DR and MC74HC08ADTR2G, the 74HC08S14-13 offers the fastest propagation delay in SO-14 form factor and highest thermal margin (150°C TJ), making it optimal for high-reliability industrial timing and dense layout scenarios where board height and speed are jointly constrained.

FAQ

What is the maximum recommended operating temperature for 74HC08S14-13?

The device is rated for continuous operation up to +125°C ambient (TA), with junction temperature reaching +150°C under worst-case power dissipation. Derating is required above 70°C ambient if total power exceeds 100 mW; thermal resistance θJA ≈ 120°C/W for standard SO-14 on 1-layer FR4.

Can unused inputs be left floating?

No - unused inputs must be tied to VCC or GND to prevent oscillation, increased current draw, and potential latch-up. The datasheet explicitly states this in Recommended Operating Conditions (Note 6); floating CMOS inputs cause undefined logic states and elevated ICC due to partial conduction in input transistors.

Does 74HC08S14-13 support mixed-voltage interfacing between 3.3V and 5V systems?

Yes - its input thresholds (VIH = 1.5V min @ 2.0V, 3.15V @ 4.5V) and rail-tolerant inputs (–0.5V to VCC + 0.5V) allow reliable 3.3V outputs to drive 5V-powered 74HC08S14-13, and its 5V outputs can interface to 3.3V-tolerant receivers when current-limited or clamped.

Is the SO-14 package RoHS and halogen-free compliant?

Yes - the 74HC08S14-13 is fully RoHS 2 compliant (2011/65/EU) with no intentionally added lead, and certified halogen- and antimony-free: Br < 900 ppm, Cl < 900 ppm (total Br+Cl < 1500 ppm), Sb < 1000 ppm, meeting Diodes Incorporated's "Green" definition per Note 3.
