Single inverter with open-drain output in the 74AUC family
The SN74AUC1G06DCKR is a single inverter from Texas Instruments' 74AUC series, delivering a logic inversion function with an open-drain output stage. Housed in the SC-70-5 package (also known as SOT-353), this surface-mount device fits a compact 5-pin footprint for space-constrained PCB layouts.
Supply voltage range and speed envelope
Operating from 0.8V to 2.7V, this inverter covers the sub-1V to near-3V logic domain, making it suitable for battery-powered or low-voltage core logic where the rail drops below 1.8V. Propagation delay is 1.8ns typical at 2.5V with a 30pF load — this sets the data-rate limit; the open-drain output's rise time is dominated by the external pull-up resistor and load capacitance, not the device itself. The input logic thresholds are specified at 0V to 0.7V for a low and 1.7V for a high, which aligns with 1.8V and 2.5V logic families without external level translation on the input side.
Open-drain output and wired-OR capability
Because the output is open-drain, multiple SN74AUC1G06 devices can share a common pull-up resistor to implement a wired-OR connection — useful for interrupt lines or shared bus arbitration where any low input pulls the line low. Quiescent current is 10µA maximum, keeping the standby power low in battery-operated designs where the inverter sits idle between switching events.
Production status and compliance
The device is RoHS3 compliant, meeting the latest EU restriction-of-hazardous-substances directive for lead-free assembly processes.
