Product details
Overview
74AHCT17APWJ from Nexperia is a hex non-inverting buffer with Schmitt-trigger inputs, designed for noise-immune signal conditioning in digital interface circuits. It operates from 4.5 V to 5.5 V, features TTL-compatible inputs, 3.2 ns typical propagation delay at 5 V, IOFF-enabled partial power-down protection, and is rated for -40 °C to +125 °C ambient operation - used in industrial sensor signal cleanup and legacy bus level translation.
For engineers reviewing the 74AHCT17APWJ datasheet, 74AHCT17APWJ pinout, 74AHCT17APWJ application, or 74AHCT17APWJ equivalent, key selection criteria include Schmitt-trigger hysteresis (0.4–1.5 V), IOFF leakage < 0.5 μA at VCC = 0 V, output drive capability (±8 mA), TSSOP14 thermal derating (7.3 mW/K above 81 °C), and mixed-mode voltage tolerance across all I/O ports.
Technical Context
This device implements six independent Schmitt-trigger input buffers with non-inverting logic function, enabling clean digital edge regeneration from slow or noisy analog-like signals. Each channel provides hysteresis (VT+ − VT−) of 0.4–1.5 V depending on VCC, ensuring robust noise rejection against EMI and crosstalk in shared PCB traces.
The IOFF circuit actively disables outputs when VCC = 0 V, blocking backflow current up to ±20 mA during hot-insertion or partial system power-down. Static characteristics are fully specified across -40 °C to +125 °C, with VOL ≤ 0.55 V and VOH ≥ 3.7 V at IO = ±8 mA and VCC = 4.5 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 4.5 V to 5.5 V - supports stable 5 V rail operation and 3.3 V-to-5 V level translation without external biasing |
| tpd (Typ) | 3.2 ns at VCC = 5 V, CL = 15 pF - enables high-speed interface timing in sub-10 ns clock domains |
| Hysteresis (VH) | 0.4 V to 1.5 V - rejects noise spikes up to 1.5 V peak-to-peak on input lines |
| IOFF Leakage | < 0.5 μA at VCC = 0 V - prevents damaging back-current during live insertion or multi-rail sequencing |
| Output Drive | ±8 mA at VOL ≤ 0.55 V / VOH ≥ 3.7 V - directly drives standard TTL loads and 50 pF trace capacitance |
| Operating Temp | -40 °C to +125 °C - qualified for under-hood automotive modules and industrial control enclosures |
| ESD Rating | HBM > 3000 V, CDM > 2000 V - withstands handling and board-level ESD events without latch-up |
Pinout & Package
TSSOP14 (SOT402-1) package: plastic thin shrink small outline, 14 leads, 4.4 mm body width, 0.65 mm lead pitch, 1.2 mm max height - optimized for high-density PCB layouts with thermal derating of 7.3 mW/K above 81 °C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 5, 9, 11, 13 | Input (1A–6A) | Schmitt-trigger buffered data inputs; tolerate slow edges and noise up to hysteresis threshold |
| 2, 4, 6, 8, 10, 12 | Output (1Y–6Y) | Non-inverting CMOS outputs; drive TTL/CMOS loads with defined VOH/VOL under ±8 mA |
| 7 | GND | Digital ground reference; must be low-impedance return path for all six channels |
| 14 | VCC | Positive supply; powers internal logic and output stages; requires local 100 nF decoupling |
Key Features
| Feature | Design Value |
|---|---|
| TTL-Compatible Inputs | Accepts 3.3 V logic highs while operating at 5 V VCC - eliminates need for external level shifters in mixed-voltage systems |
| IOFF Partial Power-Down | Outputs go high-impedance when VCC = 0 V - enables safe hot-swap in modular backplane and field-replaceable unit designs |
| Wide Temperature Range | Full functionality from -40 °C to +125 °C - suitable for engine control units and industrial PLC I/O modules |
| Low Propagation Delay | 3.2 ns typical (CL = 15 pF) - maintains timing integrity in high-frequency clock distribution and strobe paths |
| Robust ESD Protection | HBM > 3000 V, CDM > 2000 V - reduces test yield loss and field failure risk in automated assembly environments |
Applications
| Industrial Sensor Interface | Legacy Bus Level Translation |
|---|---|
|
Use Scenario: Conditioning slow-rising signals from RTD, thermistor, or proximity sensors before ADC sampling or microcontroller GPIO capture. IC Role / Device Role / Timing Role: Signal conditioner and noise filter - converts analog-like transitions into clean digital edges using Schmitt-trigger hysteresis. Use Value: Eliminates multiple external RC filters and debouncing firmware; reduces BOM count and improves system reliability in electrically noisy factory environments. |
Use Scenario: Interfacing 3.3 V FPGA I/O banks with legacy 5 V parallel address/data buses in test equipment and instrumentation. IC Role / Device Role / Timing Role: Bidirectional voltage translator - leverages TTL-compatible inputs and 5 V CMOS outputs to bridge logic families without direction control pins. Use Value: Enables direct connection between modern low-voltage controllers and aging 5 V peripherals, avoiding complex active translators or discrete resistor networks. |
| Hot-Swappable Module I/O | Automotive Body Control Module |
|
Use Scenario: Isolating I/O lines in modular rack-mounted systems where cards may be inserted/removed while main power remains active. IC Role / Device Role / Timing Role: Safe I/O buffer with IOFF - disables outputs during power-off state to prevent backfeeding into powered subsystems. Use Value: Meets IEC 61000-4-2 compliance requirements for hot-swap safety; avoids damage to host controller or adjacent modules during insertion. |
Use Scenario: Debouncing mechanical switch inputs (door locks, seat controls) in 12 V vehicle electrical systems with 5 V MCU interfaces. IC Role / Device Role / Timing Role: Input conditioner - suppresses contact bounce and EMI-induced glitches before reaching safety-critical microcontroller interrupt pins. Use Value: Reduces false trigger events by >99% compared to direct switch-to-MCU routing; eliminates need for software debounce delays that increase latency. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar hex Schmitt-trigger buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74AHCT17PW | Same pinout, identical electrical specs, TI-branded TSSOP14 variant - no functional difference | Identical use cases; TI's qualification documentation differs slightly in ESD test reporting format | Select if TI sourcing preference or dual-sourcing strategy required; no redesign needed |
| 74LVC17APW | Lower VCC range (1.65–5.5 V); higher input hysteresis (0.5–2.0 V); no IOFF support | Supports 1.8 V/2.5 V/3.3 V/5 V mixed systems but lacks power-down isolation | Choose only when wider voltage flexibility is critical and hot-swap safety is not required |
Compared with SN74AHCT17PW, 74AHCT17APWJ offers identical performance and drop-in compatibility; versus 74LVC17APW, it trades broader VCC range for guaranteed IOFF protection and tighter hysteresis control at 5 V - making it superior for industrial hot-swap and automotive power sequencing.

FAQ
Does 74AHCT17APWJ support 3.3 V-only operation?
No. The device requires VCC between 4.5 V and 5.5 V. Its inputs are TTL-compatible, meaning they accept 3.3 V logic-high signals while powered at 5 V - but it cannot operate with VCC = 3.3 V. For true 3.3 V operation, consider the 74LVC17A series instead.
What is the maximum capacitive load this buffer can drive reliably?
Per datasheet Table 7, 74AHCT17APWJ is characterized up to 50 pF load capacitance with tpd ≤ 12.1 ns at -40 °C to +125 °C. Driving >50 pF increases propagation delay nonlinearly and may cause output ringing; for heavier loads, add series termination or use a dedicated line driver.
Can unused inputs be left floating?
No. All six Schmitt-trigger inputs must be tied to a defined logic level (VCC or GND) - floating inputs cause excessive ICC current, unpredictable output states, and potential oscillation due to noise coupling. Use pull-up or pull-down resistors (≤10 kΩ) if not actively driven.
Is the TSSOP14 package RoHS and REACH compliant?
Yes. Nexperia confirms SOT402-1 packaging meets RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006, including exemption 7a for lead in high-melting-temperature type solders. Full compliance documentation is available via Nexperia's product change notifications portal.
