Texas Instruments SN74LVC1G00DRYR

Overview

SN74LVC1G00DRYR from Texas Instruments is a single 2-input positive-NAND gate in a 6-pin SON (DRY) package, performing Y = A • B logic with 3.8ns max propagation delay at 3.3V, ±24mA output drive, and 10μA max ICC. It supports 1.65V–5.5V VCC operation, accepts 5.5V-tolerant inputs, and enables live insertion via Ioff.

For engineers reviewing the SN74LVC1G00DRYR datasheet, SN74LVC1G00DRYR pinout, SN74LVC1G00DRYR application, or SN74LVC1G00DRYR equivalent, key selection factors include its ultra-compact 1.45mm × 1mm DRY package, over-voltage tolerant inputs, partial power-down capability, balanced CMOS push-pull outputs, and guaranteed operation from –40°C to 125°C.

Technical Context

This device implements standard CMOS NAND logic with a functional truth table (H,H→L; L,X→H; X,L→H) and features balanced push-pull outputs capable of sourcing/sinking up to ±24mA at 3.3V. Its Ioff circuitry disables all outputs when VCC = 0V, preventing back-drive current and supporting hot-plug operation.

The SN74LVC1G00DRYR uses over-voltage tolerant input structures-no positive clamp diode-enabling 5.5V input signals even at 1.65V VCC. Input transition rate limits (5–20 ns/V depending on VCC) ensure reliable switching without oscillation or excessive power draw.

FAQ

What is the maximum input voltage the SN74LVC1G00DRYR can tolerate?

The SN74LVC1G00DRYR accepts input voltages up to 5.5V regardless of VCC level, enabled by its over-voltage tolerant input structure without a positive clamp diode. This allows direct interfacing with 5V microcontrollers or sensors while operating at 1.8V or 3.3V VCC. Exceeding 5.5V risks permanent damage per Absolute Maximum Ratings.

Does the SN74LVC1G00DRYR support hot-swap or live insertion?

Yes, the SN74LVC1G00DRYR supports live insertion through its Ioff feature, which disables all outputs when VCC = 0V. This prevents back-driving powered circuitry and limits Ioff leakage to ±10μA, satisfying JEDEC JESD78 Class II latch-up requirements. The DRY package's wettable flanks further aid automated optical inspection in hot-swap module assemblies.

What is the recommended bypass capacitor for SN74LVC1G00DRYR?

Texas Instruments recommends a 0.1μF ceramic bypass capacitor placed physically adjacent to the SN74LVC1G00DRYR's VCC and GND pins, with short, wide traces to minimize inductance. For enhanced noise suppression across frequencies, a parallel 1μF capacitor is advised. Layout guidelines specify placement on the same PCB layer as the device with an unbroken ground plane beneath.

Can unused inputs of the SN74LVC1G00DRYR be left floating?

No, unused inputs of the SN74LVC1G00DRYR must never be left floating. Standard CMOS inputs require termination to either VCC or GND to prevent oscillation, excessive power consumption, and potential device damage. A 10kΩ pull-up or pull-down resistor is recommended if the input may be driven intermittently, ensuring stable logic states under all operating conditions.

What is the thermal resistance (RθJA) of the SN74LVC1G00DRYR package?

The SN74LVC1G00DRYR in its 6-pin SON package has a junction-to-ambient thermal resistance (RθJA) of 439°C/W, as specified in the Thermal Information table. This value assumes standard JEDEC 2-layer board conditions; actual performance improves with PCB copper area, thermal vias, and airflow. For high-density layouts, thermal simulation is recommended to confirm junction temperature remains below 125°C under worst-case load.
