Applications
SN74AHC1G32DCKTE4 is used as a signal combiner or logic OR function in low-power CMOS digital designs, including interrupt request merging, wake-up signal routing, and enable signal generation in MCU peripheral interface circuits. Its 2 V minimum operating voltage suits 2.5 V and 3.3 V logic families common in modern SoC designs. The SC-70 package makes it ideal for wearable electronics, IoT nodes, and small mobile devices where board space per logic gate must be minimized.

Frequently Asked Questions
Over what supply voltage range does SN74AHC1G32DCKTE4 operate and which logic families can it interface with?
SN74AHC1G32DCKTE4 operates from 2 V to 5.5 V, making it directly compatible with 2.5 V, 3.3 V, and 5 V CMOS logic families as well as TTL input levels, enabling it to bridge logic signals between mixed-voltage subsystems without external level translation in most standard digital board designs.
How small is the SC-70 package of SN74AHC1G32DCKTE4 and how does it compare to SOT-23?
The 5-pin SC-70 package measures approximately 2.0 mm × 1.25 mm, which is roughly 40% smaller in footprint area compared to the standard 5-pin SOT-23 package at 2.9 mm × 1.6 mm, offering a significant board space reduction for single-gate OR function requirements in compact IoT or wearable PCB designs.
Can SN74AHC1G32DCKTE4 merge two independent interrupt signals from separate MCU peripherals into a single interrupt input?
Yes, connecting two active-high interrupt outputs to the 2 inputs of SN74AHC1G32DCKTE4 produces a logic-high output whenever either interrupt fires, allowing a single MCU interrupt pin to monitor 2 sources simultaneously, with the MCU reading status registers to identify which peripheral triggered the 8 mA-capable OR gate output at 3.3 V or 5 V supply.
How fast does SN74AHC1G32DCKTE4 switch and is it fast enough for signals above 100 MHz?
SN74AHC1G32DCKTE4 has a typical propagation delay of approximately 5 ns to 7 ns at 5 V with a 50 pF load, corresponding to a maximum usable toggle rate well above 50 MHz for most standard logic applications, though it is not rated for RF or high-speed serial signals above 100 MHz where dedicated buffers with controlled impedance outputs are preferred.
