74AHCT2G125DP,125

Buffers, Drivers, Receivers, Transceivers Overview

The Nexperia 74AHCT2G125DP,125 is a dual buffer and line driver featuring three-state outputs controlled by active-low enable inputs (nOE). It operates within a supply voltage range of 4.5 V to 5.5 V and accepts TTL-level input signals. The device utilizes a TSSOP8 plastic thin shrink small outline package (SOT505-2) with an 8-lead configuration. Key electrical parameters include a maximum propagation delay of 8.5 ns at 5.5 V with a 50 pF load, a low-level output current capability of 8 mA, and a high-level output current of -8 mA. It functions reliably across an ambient temperature range of -40 °C to +125 °C.

Buffers, Drivers, Receivers, Transceivers FAQ

What is the logic function of the 74AHCT2G125?

It functions as a dual non-inverting buffer with three-state outputs. When the enable pin is low, the input signal passes to the output; when high, the output enters a high-impedance state.

Can this device be used for voltage translation?

Yes, the inputs are overvoltage tolerant up to 5.5 V. This allows the device to translate signals from lower voltage domains into a 5 V system without damage, provided the supply voltage is maintained within the specified 4.5 V to 5.5 V range.
