For engineers reviewing the SN74AHC1G00DCKR datasheet, SN74AHC1G00DCKR pinout, SN74AHC1G00DCKR application, or SN74AHC1G00DCKR equivalent, this page delivers verified electrical specs, thermal metrics, functional truth table, SC-70 package dimensions, and real-world implementation guidance for low-voltage, space-constrained logic interfacing.
Technical Context
The SN74AHC1G00DCKR implements the Boolean NAND function Y = A • B in positive logic using advanced CMOS AHC technology. It features Schmitt-trigger inputs across all pins, enabling robust operation with slow-rising/falling signals and improved noise rejection in noisy environments.
Its design supports wide-supply operation (2–5.5 V), rail-to-rail output swing, and balanced push-pull (totem-pole) output structure-delivering symmetrical ±8-mA drive capability at 5 V while maintaining ultra-low ICC ≤ 10 μA across –40°C to +125°C ambient temperature range.
Key Specifications

Applications
| LED Indicator Control | Signal Enable/Disable |
|---|---|
Use Scenario: Driving an indicator LED in a portable medical device powered from a 3.3 V LDO. IC Role / Device Role / Timing Role: Logic-level translator and current source - converts microcontroller GPIO output to LED on/off control with built-in current limiting via series resistor. Use Value: Eliminates need for external transistor driver; ±8-mA drive at 3.3 V directly illuminates standard 20-mA LEDs at reduced brightness with no additional components. | Use Scenario: Enabling/disabling a clock signal routed to a peripheral ASIC in an industrial PLC backplane. IC Role / Device Role / Timing Role: Active-low enable gate - NAND configured as inverter (A tied high) to pass or block clock based on enable control line. Use Value: 6.5 ns propagation delay preserves clock duty cycle integrity; Schmitt inputs prevent metastability during enable assertion in electrically noisy cabinet environments. |
| Logic-Level Translation | Reset Signal Conditioning |
Use Scenario: Interfacing a 5 V UART transceiver with a 3.3 V microcontroller I/O port. IC Role / Device Role / Timing Role: Bidirectional voltage-tolerant logic buffer - leverages overvoltage-tolerant inputs (up to 5.5 V) and 3.3 V-compatible outputs. Use Value: Allows safe 5 V → 3.3 V level downshift without external resistors or dedicated translators; VIH/VIL thresholds scale with VCC for consistent switching. | Use Scenario: Debouncing and synchronizing a mechanical pushbutton reset input in an automotive infotainment head unit. IC Role / Device Role / Timing Role: Input conditioner - Schmitt-trigger inputs filter contact bounce and slow rise times before feeding reset controller logic. Use Value: Built-in hysteresis eliminates need for RC filters or firmware debouncing; operates reliably across –40°C to +125°C junction temperature range. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar single-gate logic applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G00DCKR | Lower VCC range (1.65–5.5 V); 3.9 ns max tPD at 3.3 V; higher ICC (max 10 μA same, but typical lower) | Better suited for 1.8 V systems; slightly faster at 3.3 V but less noise margin due to no Schmitt inputs | Choose when operating below 2 V or prioritizing speed over noise immunity |
| MC74VHC1G00DTT1G | Same 2–5.5 V range; 7.5 ns max tPD at 5 V; Schmitt inputs; different pinout (Pin 1 = VCC, Pin 2 = A, Pin 3 = B, Pin 4 = GND, Pin 5 = Y) | Requires PCB layout change; identical functional behavior but non-pin-compatible | Consider only if sourcing constraints require ON Semiconductor supply chain |
Compared with SN74LVC1G00DCKR and MC74VHC1G00DTT1G, the SN74AHC1G00DCKR uniquely combines Schmitt-trigger inputs with 6.5 ns speed and 2 V minimum supply-making it optimal for noise-prone, mixed-voltage, or battery-operated designs where signal integrity and supply flexibility are critical.

FAQ
What logic function does the SN74AHC1G00DCKR implement?
The SN74AHC1G00DCKR implements a single 2-input positive-NAND gate function (Y = A • B) in positive logic. Its truth table shows output LOW only when both inputs A and B are HIGH; otherwise, the output is HIGH. This behavior is confirmed in Section 7.4 of the official TI datasheet SCLS313Q, and applies identically to the SN74AHC1G00DCKR variant in SC-70 packaging.
Does the SN74AHC1G00DCKR have Schmitt-trigger inputs?
Yes, the SN74AHC1G00DCKR has Schmitt-trigger action on both inputs (A and B), providing hysteresis that improves noise immunity and allows reliable operation with slow-rising or slow-falling input signals. This feature is explicitly stated in the "Features" section and "Feature Description" (Section 7.3) of the TI datasheet SCLS313Q, and is retained across all package variants including the DCK package used by SN74AHC1G00DCKR.
What is the maximum supply voltage for the SN74AHC1G00DCKR?
The maximum recommended supply voltage for the SN74AHC1G00DCKR is 5.5 V, with absolute maximum rating at 7 V. Operating within the recommended 2 V to 5.5 V range ensures full compliance with AC/DC specifications including propagation delay, drive strength, and noise margins. This range is specified in Section 5.3 (Recommended Operating Conditions) of the TI datasheet SCLS313Q and applies to the SN74AHC1G00DCKR without exception.
Can the SN74AHC1G00DCKR drive an LED directly?
Yes, the SN74AHC1G00DCKR can drive an LED directly when configured as an inverter (e.g., tie one input HIGH) and used in sink mode (LED anode to VCC, cathode to Y output). Its guaranteed 8-mA sink current at 5 V and 4-mA at 3.3 V supports standard indicator LEDs with appropriate series current-limiting resistors. This capability is validated by the IOL specifications in Section 5.5 of the TI datasheet SCLS313Q and confirmed for the SN74AHC1G00DCKR SC-70 variant.
Is the SN74AHC1G00DCKR pin-compatible with other SC-70 single-gate logic devices?
The SN74AHC1G00DCKR uses the standard SC-70-5 (DCK) pinout: Pin 1 = A, Pin 2 = B, Pin 3 = GND, Pin 4 = Y, Pin 5 = VCC. This matches TI's SC-70 logic portfolio (e.g., SN74AHC1G14DCKR, SN74AHC1G08DCKR), enabling footprint reuse across functions. However, it is not pin-compatible with non-TI SC-70 logic (e.g., ON Semi's MC74VHC1G00DTT1G), which uses a different pin assignment - confirmed by comparing TI SCLS313Q Figure 4-2 and ON Semi datasheet NCV74VHC1G00/D.
