Product details
Overview
SN74AHCT1G04DBVR from Texas Instruments is a single-channel CMOS inverter gate operating at 4.5V–5.5V, delivering 7.5ns max propagation delay at 5V, ±8mA output drive, TTL-compatible inputs (VIH = 2V, VIL = 0.8V), and 10μA max supply current - used for level translation (3.3V-to-5V) and noise-immune signal inversion in compact embedded control circuits.
For engineers reviewing the SN74AHCT1G04DBVR datasheet, SN74AHCT1G04DBVR pinout, SN74AHCT1G04DBVR application, or SN74AHCT1G04DBVR equivalent, key selection criteria include its SOT-23-5 package footprint, guaranteed 5V rail compatibility, low-power static operation, slow-edge design to suppress ringing, and explicit support for mixed-voltage interface buffering in space-constrained industrial and medical systems.
Technical Context
The SN74AHCT1G04DBVR implements a single inverting logic function (Y = A̅) using advanced CMOS technology with TTL-level input thresholds, enabling direct interfacing with legacy 3.3V logic while driving 5V loads. Its internal structure avoids high-speed edge artifacts via controlled slew rate and balanced output drive.
It operates across –40°C to +125°C with absolute maximum ratings up to 7V on VCC and inputs, supports 15pF/50pF load switching, and features ESD robustness per HBM (±1500V) and CDM (±1000V) standards - confirming suitability for industrial-grade board-level integration without external protection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5V–5.5V - ensures stable operation under standard 5V rail tolerances; not rated for 3.3V-only use. |
| Propagation Delay | 7.5ns max at 5V, CL = 15pF - enables reliable timing in sub-100MHz digital control paths. |
| Output Drive | ±8mA at 5V - sufficient for driving multiple 74-series inputs or small capacitive loads without external buffers. |
| Input Compatibility | TTL voltage levels (VIH ≥ 2V, VIL ≤ 0.8V) - allows direct connection to 3.3V microcontroller GPIOs without level shifters. |
| Quiescent Current | 10μA max ICC - supports always-on monitoring functions in battery-backed or low-power subsystems. |
| Operating Temperature | –40°C to +125°C - validated for under-hood automotive auxiliary modules and industrial motor drive control boards. |
| ESD Rating | HBM ±1500V, CDM ±1000V - meets IEC 61000-4-2 Level 2 requirements for board-level ESD immunity. |
Pinout & Package
SOT-23-5 (DBV) package: 2.9mm × 1.6mm body size, 2.8mm × 2.8mm overall footprint, 1.45mm max height, lead-free NiPdAu finish, MSL Level-1 (260°C reflow).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | No Connection (NC) | Internally unconnected; must remain floating or grounded - no routing or PCB trace required. |
| 2 | Input A | Active-low logic input accepting TTL-compatible voltages; requires external pull-up/down if unused. |
| 3 | GND | Dedicated ground reference for power return and logic reference; must be low-impedance to minimize noise coupling. |
| 4 | Output Y | Inverted logic output with ±8mA drive capability; designed for direct connection to downstream 5V CMOS/TTL inputs. |
| 5 | VCC | Primary 4.5V–5.5V supply pin; requires local 0.1μF ceramic bypass capacitor placed within 2mm of the pin. |
Key Features
| Feature | Design Value |
|---|---|
| Slow-edge output transition | Controlled rise/fall rates (20 ns/V) reduce EMI and eliminate overshoot/undershoot on unterminated traces. |
| 3.3V-to-5V level translation | Validated VIH = 2V threshold accepts 3.3V logic highs directly, enabling seamless interface between mixed-voltage domains. |
| Low static power consumption | 10μA max ICC at 5.5V allows inclusion in always-active fault-monitoring circuits without measurable battery drain. |
| TTL-input compatibility | Guaranteed recognition of 0.8V/2V input thresholds eliminates need for external resistor networks or translators. |
| Industrial temperature range | Full functionality from –40°C to +125°C supports deployment in motor drives, patient monitors, and network switch control planes. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar inverter gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G04DBVR | Wider supply range (1.65V–5.5V); lower drive (±24mA); higher speed (4.5ns typ); not TTL-input compatible. | Better suited for 1.8V/2.5V/3.3V-only systems; unsuitable for legacy 3.3V-to-5V up-translation. | Select when operating below 4.5V or requiring faster edges; avoid if interfacing with older TTL outputs or 3.3V logic with marginal VOH. |
| MC74VHC1G04DTT1G | Same 5V operation; slightly higher ICC (20μA max); identical SOT-23-5 package; JEDEC-compliant VHC family. | Offers broader automotive qualification (AEC-Q100 Grade 1); same functional behavior but different process and reliability testing. | Prefer for automotive applications requiring AEC-Q100 compliance; otherwise functionally interchangeable in industrial 5V designs. |
Compared with SN74AHCT1G04DBVR, SN74LVC1G04DBVR enables lower-voltage operation but sacrifices TTL compatibility, while MC74VHC1G04DTT1G provides identical 5V performance with certified automotive reliability - making SN74AHCT1G04DBVR optimal for cost-sensitive, non-automotive 5V mixed-signal interfaces requiring guaranteed 3.3V input recognition.

FAQ
What is the maximum operating temperature for SN74AHCT1G04DBVR?
The SN74AHCT1G04DBVR is fully specified from –40°C to +125°C ambient temperature. This rating is validated per JEDEC JESD22-A108 and applies across all electrical parameters including propagation delay, output drive, and input thresholds - confirming suitability for under-hood automotive auxiliary modules and industrial motor drive control environments where thermal stress is present.
Can SN74AHCT1G04DBVR operate from a 3.3V supply?
No, SN74AHCT1G04DBVR is not rated for 3.3V operation. Its recommended operating conditions specify VCC = 4.5V to 5.5V only. Attempting to power it at 3.3V results in undefined logic behavior, degraded noise margins, and potential failure to recognize TTL input levels - use SN74LVC1G04DBVR instead for true 3.3V-compatible operation.
Is SN74AHCT1G04DBVR pin-compatible with other SOT-23-5 inverters?
Yes, SN74AHCT1G04DBVR uses the industry-standard SOT-23-5 pinout (Pin 1: NC, Pin 2: A, Pin 3: GND, Pin 4: Y, Pin 5: VCC), matching SN74LVC1G04DBVR and MC74VHC1G04DTT1G. However, functional equivalence requires verification of supply voltage, input thresholds, and drive strength - substitution must consider system-level voltage domain alignment.
Does SN74AHCT1G04DBVR require external pull-up resistors on its input?
No - SN74AHCT1G04DBVR has no internal pull-ups. Unused inputs must be externally tied to VCC or GND per TI application note SCBA004 to prevent floating nodes, which cause increased ICC, oscillation, or latch-up. The device does not tolerate floating inputs even at room temperature.
What is the purpose of the NC pin (Pin 1) on SN74AHCT1G04DBVR?
Pin 1 of SN74AHCT1G04DBVR is a No-Connection terminal - internally unconnected and electrically isolated. It must remain unconnected on the PCB; routing a trace or placing a pad is unnecessary and may introduce parasitic capacitance or contamination risk. TI confirms this pin serves no functional role in any operating condition.
