Frequently Asked Questions
What output drive current does the SN74LVC1G38DCKRE4 provide, and can it drive an LED directly?
The SN74LVC1G38DCKRE4 specifies a maximum output low current (I_OL) of 24 mA, which is sufficient to drive a standard 20 mA indicator LED directly from the output pin with an appropriate series resistor, eliminating the need for a discrete transistor driver in simple indicator circuits.
What supply voltage range does the SN74LVC1G38DCKRE4 support, and is it compatible with 3.3 V and 5 V logic simultaneously?
The SN74LVC1G38DCKRE4 operates from 1.65 V to 5.5 V, making it compatible with 1.8 V, 2.5 V, 3.3 V, and 5 V logic systems. When powered at 3.3 V, its inputs accept 5 V signals (the inputs are 5 V tolerant in the LVC family), enabling direct 5 V-to-3.3 V level crossing on up to 2 input pins.
How does the SC-70 5-pin package size of the SN74LVC1G38DCKRE4 benefit compact PCB designs?
The SC-70 package body measures approximately 2.0 mm x 2.1 mm with 5 leads on 0.65 mm pitch, providing a footprint roughly 4x smaller than an SOT-23-5 alternative. This allows placement in dense multi-layer boards where gate functions must fit within 4 mm² of available copper area alongside other components.
