SN74AHCT125 Description

Short technical summary and product information.

The SN74AHCT125 is a quadruple bus buffer gate manufactured by Texas Instruments. It features independent line drivers with 3-state outputs, making it suitable for bus interfacing applications. Each output is disabled when the associated output-enable (OE) input is high, and passes data from the A input to its Y output when OE is low.

 

This buffer operates within a supply voltage range of 4.5V to 5.5V and utilizes TTL-compatible CMOS inputs. Key electrical characteristics include a high-level output current (IOL) of 8 mA and a low-level output current (IOH) of -8 mA. The device boasts very high speed with propagation delays (tpd) between 5-10 ns and a maximum supply current of 20 µA.

 

The SN74AHCT125 is designed for operation across a wide temperature range of -40°C to 125°C. Latch-up performance exceeds 250 mA per JESD 17. It is available in multiple package types including SOP, TSSOP, WQFN, TVSOP, PDIP, SOIC, SSOP, and VQFN.

 

This component is ideal for applications requiring high-speed buffering and 3-state output control in digital systems. Its TTL-compatible inputs allow for easy integration with various logic families.
