Product details

Overview

74HCT04T14-13 from Diodes Incorporated is a hex inverter IC with six independent CMOS push-pull gates, designed for 4.5V–5.5V TTL-compatible logic systems. It delivers 4mA output drive at V_CC = 4.5V, features Schmitt-trigger inputs for noise immunity, and operates across –40°C to +125°C ambient temperature - used in PC motherboard I/O buffering and peripheral control circuits.

For engineers reviewing the 74HCT04T14-13 datasheet, 74HCT04T14-13 pinout, 74HCT04T14-13 application, or 74HCT04T14-13 equivalent, key selection criteria include input voltage compatibility (VIH ≥ 2.0V, VIL ≤ 0.8V), propagation delay (t_PD ≤ 24 ns @ 4.5V), output drive capability (I_OL = 5.2mA), ESD robustness (2kV HBM), and TSSOP-14 package thermal performance.

Technical Context

The 74HCT04T14-13 implements six identical inverting logic gates using high-speed CMOS technology with TTL-level input thresholds. Each gate has Schmitt-trigger action on its input, enabling reliable signal conditioning of slow-rising or noisy digital waveforms.

It operates strictly within 4.5V–5.5V supply range and maintains rail-to-rail output swing (VOH ≥ 3.80V, VOL ≤ 0.33V at full load). Input clamp current is ±20mA, and absolute max V_CC is +7.0V - supporting transient overvoltage tolerance during system power sequencing.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage	4.5V to 5.5V - ensures compatibility with standard 5V TTL and mixed-voltage logic domains
Propagation Delay	24 ns max @ V_CC = 4.5V, CL = 50pF - supports >20 MHz clocked logic interfacing
Output Drive	±4mA @ V_CC = 4.5V - sufficient to drive 10 LSTTL loads or one 50Ω transmission line
Input Thresholds	VIH ≥ 2.0V, VIL ≤ 0.8V - guarantees interoperability with legacy 5V TTL outputs
ESD Protection	2000V HBM - exceeds JEDEC JESD22-A114A, reducing board-level ESD failure risk
Operating Temp	–40°C to +125°C - qualified for industrial-grade embedded control and storage subsystems

Pinout & Package

TSSOP-14 surface-mount package: 4.9mm × 4.4mm body, 0.65mm pitch, 1.2mm max height, lead-free and RoHS-compliant.

Pin/Terminal	Circuit Role	Design Meaning
1, 3, 5, 9, 11, 13	Input (1A–6A)	CMOS/TTL-compatible logic inputs with Schmitt-trigger hysteresis for noise rejection
2, 4, 6, 8, 10, 12	Output (1Y–6Y)	Push-pull CMOS outputs capable of sourcing/sinking 4mA at 4.5V
7	GND	Logic ground reference; must be low-impedance connection to minimize switching noise
14	V_CC	Primary power supply pin; requires local 100nF ceramic decoupling adjacent to pin

Key Features

Feature	Design Value
Schmitt-trigger inputs	Enables clean inversion of slow or noisy signals without external hysteresis components
4mA output drive	Directly interfaces with LSTTL loads or drives short PCB traces without buffer amplification
22 pF typical power dissipation capacitance	Minimizes dynamic power consumption at 1MHz operation - critical for low-power logic clusters
TSSOP-14 footprint	Reduces PCB area by ~40% vs SO-14 while maintaining thermal performance up to 125°C
Lead-free & halogen-free	Fully compliant with EU RoHS 2011/65/EU and meets Diodes' "Green" definition (<900ppm Br+Cl)

Applications

PC Motherboard I/O Buffering

Hard Disk Drive Control Logic

Use Scenario: Level-shifting and signal inversion between southbridge GPIO and legacy ISA-style peripherals.

IC Role / Device Role / Timing Role: Hex inverter providing isolated, noise-immune signal polarity correction for reset, interrupt, and enable lines.

Use Value: Schmitt-trigger inputs eliminate contact bounce artifacts from mechanical switches; 4mA drive ensures reliable fanout to multiple downstream latches.

Use Scenario: Inverting command strobes and status feedback signals in SATA/IDE interface translation layers.

IC Role / Device Role / Timing Role: Signal conditioning gate for HDD controller handshake timing - inverts READY#, BUSY#, and ERROR# assertions.

Use Value: 24 ns max t_PD preserves setup/hold margins in 33 MHz ATA timing; TSSOP-14 enables dense layout near connector zones.

DVD/Blu-ray Drive Motor Control

Set-Top Box IR Receiver Interface

Use Scenario: Inverting direction-control signals sent from MCU to H-bridge motor drivers in optical disc sled mechanisms.

IC Role / Device Role / Timing Role: Logic-level translator and polarity adjuster for bidirectional DC motor control paths.

Use Value: Rail-to-rail output swing ensures full logic swing at H-bridge enable inputs; –40°C to +125°C rating supports internal chassis thermal cycling.

Use Scenario: Conditioning raw 38kHz IR carrier pulses from photodiode preamp before MCU demodulation.

IC Role / Device Role / Timing Role: Digital signal conditioner that cleans up distorted IR burst edges using Schmitt-trigger hysteresis.

Use Value: Input hysteresis rejects EMI-induced glitches on long flex cables; low ICC (≤40 µA) extends battery life in remote-powered STB accessories.

Equivalent & Alternatives

The following parts are listed as comparable options for similar hex inverter applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74HCT04PW	Same logic function, SOIC-14 package; 25 ns t_PD max, 3.8 mA I_OL, no Schmitt inputs	Lacks Schmitt-trigger inputs - unsuitable for noisy or slow-edge environments	Select when board space allows SOIC and input signals are already conditioned
74LVC04GW	3.3V-only supply (1.65–3.6V); 3.7 ns t_PD; 24 mA I_OL; no Schmitt inputs	Not voltage-compatible with 5V systems; higher speed but incompatible rail	Choose only in pure 3.3V domains requiring faster switching and higher drive

Compared with SN74HCT04PW and 74LVC04GW, the 74HCT04T14-13 uniquely combines 5V TTL compatibility, Schmitt-trigger noise immunity, and compact TSSOP-14 packaging - making it optimal for space-constrained industrial 5V logic interfaces where signal integrity is critical.

FAQ

Can the 74HCT04T14-13 operate at 3.3V?

No. The device is specified only for 4.5V–5.5V operation per its Recommended Operating Conditions. At 3.3V, VIH/VIL thresholds are not guaranteed, and output drive falls below specification. For 3.3V systems, consider the 74LVC04 series instead.

What is the maximum capacitive load this device can drive reliably?

The datasheet specifies switching characteristics up to 50pF load capacitance. While functional at higher loads, propagation delay increases linearly and output rise/fall times degrade beyond this point - for >50pF, add series termination or use a buffer with higher drive strength.

Are unused inputs required to be terminated?

Yes. Per Diodes' Recommended Operating Conditions, all unused inputs must be tied to either V_CC or GND. Floating inputs cause increased ICC, unpredictable output states, and potential oscillation due to CMOS input stage metastability.

Does the TSSOP-14 package require special PCB layout considerations?

Yes. The 0.65mm pitch demands precise stencil aperture design and controlled reflow profiling. Use the recommended pad layout from Diodes AP02001 (5.9mm × 1.45mm pads, 0.45mm X-dimension) and ensure solder mask dams between pins to prevent bridging.
