Frequently Asked Questions
What is the 74AHCT1G125DBVTE4 and what does it do?
The 74AHCT1G125DBVTE4 is a single-channel non-inverting 3-state bus buffer from Texas Instruments in the AHCT logic family. It passes the logic level from input to output unchanged when enabled, and places the output in a high-impedance state when disabled via the active-low output enable pin. It supports an 8 mA output drive current and operates at 50 pF load capacitance.
What package does the 74AHCT1G125DBVTE4 use?
The 74AHCT1G125DBVTE4 comes in a 5-pin SOT-23 package with JESD-30 code R-PDSO-G5. The 'T/R' suffix indicates tape-and-reel packaging for automated surface-mount assembly. This miniature package measures approximately 3mm x 1.7mm, making it one of the smallest available for single-gate logic functions.
Is the 74AHCT1G125DBVTE4 compatible with both 3.3V and 5V logic levels?
Yes, the 74AHCT1G125DBVTE4 is an AHCT-series device with TTL-compatible input thresholds, allowing it to accept 3.3V CMOS logic inputs (which meet TTL VIH/VIL thresholds) while driving a 5V output. This makes it suitable for level translation from 3.3V logic to 5V TTL systems in mixed-voltage designs.
What is the output drive current of the 74AHCT1G125DBVTE4?
The 74AHCT1G125DBVTE4 has a maximum output low current (I_ol) of 8 mA. While lower than some high-drive logic families, this is sufficient for driving standard CMOS and TTL logic inputs, small signal LEDs with series resistors, and bus lines with typical capacitive loads.
What are common applications for the 74AHCT1G125DBVTE4?
The 74AHCT1G125DBVTE4 is widely used for bus isolation on SPI, I2C, and GPIO lines, signal buffering in mixed-voltage systems, and output enable control in data multiplexing circuits. Its compact SOT-23 package and low power consumption make it popular in IoT nodes, wearable electronics, portable medical devices, and battery-powered sensors.
