Product details
Overview
SN74AHC1G00DBVR from Texas Instruments is a single 2-input positive-NAND gate IC in SOT-23 (DBV) package, operating from 2 V to 5.5 V supply, with 6.5 ns max propagation delay at 5 V, ±8-mA output drive, and Schmitt-trigger inputs for noise immunity. It enables signal gating in low-power digital control paths such as LED drivers and interface translators.
For engineers reviewing the SN74AHC1G00DBVR datasheet, SN74AHC1G00DBVR pinout, SN74AHC1G00DBVR application, or SN74AHC1G00DBVR equivalent, this page delivers verified electrical specs, functional role in NAND logic implementation, thermal metrics for SOT-23 mounting, and validated alternative options for 5-pin logic gate replacement.
Technical Context
The SN74AHC1G00DBVR implements Y = A • B Boolean logic using advanced high-speed CMOS (AHC) process technology. Its Schmitt-trigger inputs accept slow-rising signals while maintaining clean output transitions, and its balanced totem-pole output stage drives ±8 mA at 5 V with rail-to-rail swing.
It operates across –40°C to +125°C ambient temperature with supply voltage flexibility (2–5.5 V), enabling interoperability between 3.3-V and 5-V logic domains. Absolute maximum ratings include 7-V input tolerance and 25-mA per-output continuous current capability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Single 2-input positive-NAND gate (Y = A • B) |
| Supply Voltage Range | 2 V to 5.5 V - supports mixed-voltage system interfacing without level shifters |
| Max Propagation Delay | 6.5 ns at VCC = 5 V, CL = 15 pF - enables ≤150-MHz toggle rates in clean signal paths |
| Output Drive Strength | ±8 mA at VCC = 5 V - sufficient to directly drive LEDs or fan-out to ≥10 LS-TTL loads |
| Input Threshold Behavior | Schmitt-trigger inputs with hysteresis - rejects >150 mV of noise on slow edges (e.g., mechanical switch debouncing) |
| Quiescent Supply Current | 10 µA max at 125°C - suitable for always-on battery-backed logic monitoring |
| Operating Temperature | –40°C to +125°C - qualified for under-hood automotive and industrial control environments |

Applications
| LED Indicator Control | Signal Enable/Disable |
|---|---|
|
Use Scenario: Driving a status LED from a microcontroller GPIO that lacks sufficient sink/source current. IC Role / Device Role / Timing Role: NAND gate configured as an inverter (A tied high, B = GPIO) to invert and boost drive strength for common-anode LED connection. Use Value: Eliminates external transistor; leverages ±8-mA output to achieve 5–10 mA LED current without resistor recalculations across voltage rails. |
Use Scenario: Enabling/disabling a clock or data line between two subsystems based on a control signal. IC Role / Device Role / Timing Role: NAND gate used as active-low enable switch (B = enable, A = signal input) to gate signal flow with sub-7-ns latency. Use Value: Provides deterministic, low-jitter signal blocking with no DC path leakage - critical for power-gated peripheral isolation. |
| Level Translation Interface | Switch Debounce Circuit |
|
Use Scenario: Interfacing a 3.3-V FPGA I/O to a 5-V sensor module requiring clean logic-level compatibility. IC Role / Device Role / Timing Role: NAND gate powered at 5 V accepts 3.3-V inputs (within VIH/VIL spec) and outputs full 5-V logic levels. Use Value: Achieves unidirectional level shifting without dedicated translator ICs; Schmitt inputs tolerate marginal rise times from FPGA outputs. |
Use Scenario: Conditioning mechanical push-button input before feeding to a microcontroller interrupt pin. IC Role / Device Role / Timing Role: NAND gate wired as Schmitt-trigger inverter (feedback resistor from Y to A) to provide hysteresis-based debounce. Use Value: Reduces firmware overhead by eliminating software debounce; guarantees clean edge generation even with >10-ms contact bounce. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar NAND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G00DBVR | Lower VCC range (1.65–5.5 V); 3.7 ns max tPD at 3.3 V; 24 mA drive at 3.3 V | Better suited for 1.8-V/3.3-V only systems; higher drive but less 5-V robustness | Select when primary supply is ≤3.3 V and faster switching at low voltage is required |
| MC74VHC1G00DTT1G | Same 2–5.5 V range; 7.5 ns max tPD at 5 V; ±8 mA drive; different pinout (Pin 1 = VCC, Pin 2 = A) | Requires PCB layout revision due to non-identical pin mapping; identical functional behavior | Choose only if sourcing constraints require ON Semiconductor supply; verify board layout compatibility |
Compared with SN74AHC1G00DBVR, SN74LVC1G00DBVR offers superior speed below 3.3 V but reduced 5-V margin, while MC74VHC1G00DTT1G matches voltage and drive specs but demands pinout adaptation - making SN74AHC1G00DBVR optimal for mixed-voltage designs needing drop-in SOT-23 compatibility.

FAQ
What is the logic function implemented by the SN74AHC1G00DBVR?
The SN74AHC1G00DBVR implements a single 2-input positive-NAND gate, performing the Boolean function Y = A • B (or equivalently Y = A + B in negative logic). It uses true CMOS totem-pole output architecture and is not open-drain. All inputs feature Schmitt-trigger action for noise rejection, and the device operates across 2 V to 5.5 V supply voltage.
Does the SN74AHC1G00DBVR support 3.3-V and 5-V logic systems simultaneously?
Yes - the SN74AHC1G00DBVR operates from 2 V to 5.5 V and accepts input voltages up to 5.5 V regardless of VCC, enabling direct interfacing between 3.3-V controllers and 5-V peripherals. At 3.3 V supply, it delivers ±4 mA output drive and 7.9 ns max propagation delay (CL = 15 pF), maintaining reliable logic thresholds per TI's recommended operating conditions.
What is the maximum output current rating for the SN74AHC1G00DBVR?
The SN74AHC1G00DBVR supports ±8 mA output current per pin at VCC = 5 V, and ±4 mA at VCC = 3.3 V. The absolute maximum continuous output current is ±25 mA per output, with total device current limited to ±50 mA across VCC and GND pins. Exceeding these values risks parametric shift or latch-up per JESD17 compliance.
Is a bypass capacitor required for stable operation of the SN74AHC1G00DBVR?
Yes - TI specifies a 0.1-µF ceramic bypass capacitor placed as close as possible to the VCC pin (Pin 5) and GND (Pin 3) to suppress supply transients during switching. This is mandatory for achieving specified propagation delay, noise immunity, and output drive stability - especially under fast edge rates or heavy capacitive loading.
Can unused inputs on the SN74AHC1G00DBVR be left floating?
No - all unused inputs on the SN74AHC1G00DBVR must be tied to VCC or GND. Floating CMOS inputs cause undefined logic states, increased supply current, and potential oscillation due to intermediate voltage biasing. TI explicitly warns against floating inputs in Section 5.3 and Application Report SCBA004 - tying to VCC or GND ensures predictable NAND functionality and thermal stability.
