Product details
Overview
SN74AHCT1G04 from Texas Instruments is a single-channel CMOS inverter gate operating at 4.5V–5.5V supply, delivering 7.5ns max propagation delay at 5V, ±8mA output drive, TTL-compatible inputs (VIH = 2V, VIL = 0.8V), and 10μA max ICC - used for level translation and signal inversion in compact digital interfaces.
For engineers reviewing the SN74AHCT1G04 datasheet, SN74AHCT1G04 pinout, SN74AHCT1G04 application, or SN74AHCT1G04 equivalent, key selection criteria include its SC-70-5 package footprint, 5-pin SOT logic gate identity, 3.3V-to-5V up-translation capability, and guaranteed operation across –40°C to +125°C industrial temperature range.
Technical Context
The SN74AHCT1G04 implements a single inverting logic function (Y = A) using advanced CMOS technology with TTL-voltage compatible input thresholds. Its design supports voltage up-translation from 3.3V logic domains to 5V systems while maintaining low power consumption and controlled edge rates.
It features no internal enable or tri-state control, operates without latch-up risk (exceeding 250mA per JESD17), and uses a fixed single-supply architecture with dedicated VCC and GND pins - all verified under recommended conditions of 4.5V–5.5V supply and –40°C to +125°C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5V–5.5V - ensures compatibility with standard 5V digital rails and tolerance against supply ripple. |
| Propagation Delay | 7.5ns max at 5V, CL = 15pF - enables reliable timing in high-speed control and interface circuits up to ~100MHz toggle rate. |
| Output Drive | ±8mA at 5V - sufficient to drive multiple 74-series TTL inputs or light capacitive loads without external buffering. |
| Input Compatibility | TTL-level (VIH = 2V, VIL = 0.8V) - allows direct connection to legacy 3.3V microcontrollers and FPGAs without level shifters. |
| Quiescent Current | 10μA max ICC - supports low-power standby modes in battery-backed or energy-sensitive embedded systems. |
| Operating Temperature | –40°C to +125°C - qualified for industrial motor controls, network infrastructure, and medical monitoring equipment. |
| ESD Rating | ±1500V HBM - meets standard handling requirements for automated assembly and field-replaceable modules. |
Pinout & Package
SN74AHCT1G04 is packaged in SC-70 (DCK) - a 5-pin, 2.00mm × 1.25mm surface-mount package with 0.65mm pitch, optimized for space-constrained PCB layouts and reflow-compatible assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | No Connection | Internally unconnected; must be left floating or tied to GND/VCC per layout best practice - no electrical function. |
| 2 | Input A | Primary logic input accepting TTL-compatible voltage levels; drives inverter stage directly. |
| 3 | GND | Ground reference for both logic and power domains; requires low-inductance connection to system ground plane. |
| 4 | Output Y | Inverted logic output with ±8mA drive strength; designed for direct fanout to downstream CMOS/TTL loads. |
| 5 | VCC | Positive supply rail (4.5V–5.5V); requires local 0.1μF bypass capacitor placed adjacent to pin per TI layout guidelines. |
Key Features
| Feature | Design Value |
|---|---|
| TTL-input compatibility | Accepts 3.3V logic high (≥2V) and low (≤0.8V) - eliminates need for external level translators in mixed-voltage systems. |
| Controlled edge rates | Slow transition design minimizes output ringing and EMI in unterminated traces - critical for noise-sensitive patient monitors. |
| Low ICC quiescent current | 10μA max at 5.5V - reduces system-level standby power in always-on industrial controllers and point-of-sale terminals. |
| Robust latch-up immunity | Exceeds 250mA per JESD17 - ensures reliability under transient overvoltage or hot-swap conditions in motor drive feedback paths. |
| Wide temperature operation | –40°C to +125°C ambient rating - validated for use in automotive-adjacent AC induction motor controls and network switch PHY layers. |
Applications
| Motor Control Feedback | Medical Sensor Interface |

Equivalent & Alternatives
The following parts are listed as comparable options for similar inverter gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G04DCKR | Lower supply range (1.65V–5.5V); higher speed (4.5ns typ); CMOS-only inputs (no TTL compatibility) | Preferred where 3.3V-only systems dominate and 5V up-translation is unnecessary | Select when designing new 3.3V-centric platforms requiring faster switching and lower dynamic power |
| MC74VHC1G04DTT1G | Wider supply range (2V–5.5V); identical TTL input thresholds; slightly higher ICC (20μA max) | Better suited for extended-temperature automotive-qualified designs (–40°C to +105°C) | Choose when legacy ON Semiconductor sourcing or AEC-Q100-compliant variants are required |
Compared with SN74AHCT1G04, SN74LVC1G04DCKR offers superior speed and lower voltage flexibility but lacks native 3.3V-to-5V up-translation, while MC74VHC1G04DTT1G matches input compatibility and extends thermal robustness - making SN74AHCT1G04 optimal for cost-sensitive industrial 5V systems needing proven TTL interoperability.

FAQ
What is the maximum operating temperature for SN74AHCT1G04?
The SN74AHCT1G04 is rated for continuous operation from –40°C to +125°C ambient temperature, validated per JEDEC JESD78 and confirmed in TI's official datasheet revision SCLS319T. This makes SN74AHCT1G04 suitable for under-hood automotive-adjacent applications, industrial motor drives, and medical equipment exposed to elevated thermal environments - provided PCB layout follows TI's thermal guidelines for the DCK package.
Does SN74AHCT1G04 support 3.3V input signals?
Yes, SN74AHCT1G04 accepts 3.3V logic inputs reliably because its VIH threshold is specified at 2.0V min and VIL at 0.8V max under 4.5V–5.5V supply - enabling clean recognition of 3.3V-high and 3.3V-low signals. This feature is explicitly documented in Section 5.3 (Recommended Operating Conditions) and forms the basis for SN74AHCT1G04's role in 3.3V-to-5V up-translation applications.
Can SN74AHCT1G04 drive multiple TTL loads?
SN74AHCT1G04 can drive up to two standard 74LS TTL inputs (each requiring ~0.4mA high-level input current) while staying within its ±8mA output specification at 5V. Driving more than two LS loads risks exceeding IOL/IOH limits and degrading VOH/VOL margins - so SN74AHCT1G04 is best applied in point-to-point or low-fanout scenarios unless buffered. This limitation is derived from Table 5-5 (Electrical Characteristics) and TI Application Report SCBA004.
Is SN74AHCT1G04 pin-compatible with other SC-70 logic gates?
SN74AHCT1G04 uses the standard 5-pin SC-70 (DCK) footprint defined by JEDEC MO-203, matching pin 1 (NC), pin 2 (A), pin 3 (GND), pin 4 (Y), and pin 5 (VCC) across TI's 1G logic series. However, functional pinout varies by gate type - e.g., SN74AHCT1G14 (Schmitt-trigger inverter) shares the same physical layout but differs electrically. Always verify logic function and truth table before substitution.
What decoupling capacitor value is recommended for SN74AHCT1G04?
Texas Instruments recommends a 0.1μF ceramic capacitor placed as close as possible to the VCC pin (pin 5) of SN74AHCT1G04, with a low-inductance path to GND (pin 3), per Section 8.3 of the datasheet. For systems with multiple logic devices or high-noise environments, paralleling a 1μF capacitor improves low-frequency supply stability - and this guidance is validated in TI's Layout Guidelines (Figure 8-6) for SC-70 packages.
