SN74AHCT125N Level Shifter

Product Overview

The SN74AHCT125N is a quadruple Bus Buffer Gate featuring independent line drivers with 3-state outputs. Each output is disabled when the associated output-enable (OE) or input is high. When OE is low, the respective gate passes the data from the A input to its Y output. To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pull-up resistor and the minimum value of the resistor is determined by the current-sinking capability of the driver.

 

This blog will introduce SN74AHCT125N systematically from its features, alternatives to its specifications, applications, also including SN74AHCT125N VS SN74AHCT125NE4 and so much more.

SN74AHCT125N FAQ

① What is a bus buffer?

A three state bus buffer is an integrated circuit that connects multiple data sources to a single bus. The open drivers can be selected to be either a logical high, a logical low, or high impedance which allows other buffers to drive the bus.

 

② What is SN74AHCT125N?

The SN74AHCT125N is a quadruple Bus Buffer Gate featuring independent line drivers with 3-state outputs. Each output is disabled when the associated output-enable (OE) input is high. When OE is low, the respective gate passes the data from the A input to its Y output.

 

③ Is the 74ahct125 a 3V or 5V chip?

This chip is similar to others in the shop (such as the 74LVC125) except this one is particularly good at converting 3V logic up to 5V. This is in demand especially when connecting some 3V devices such as the Teensy 3 to NeoPixels. Just power the 74AHCT125 with 5V, it will detect 3V logic properly.
