SN74HC125N-NG

Buffers, Drivers, Receivers, Transceivers Overview

The SN74HC125N-NG is a quadruple bus buffer gate featuring independent line drivers with 3-state outputs. It operates within a supply voltage range of 2 V to 6 V and supports an operating temperature range from -40°C to +85°C. The device provides high-level output current of -7.8 mA and low-level output current of 7.8 mA, with a static current of 8 uA. Propagation delay varies by voltage: 150 ns at 2 V, 30 ns at 4.5 V, and 25 ns at 6 V. It is housed in a 14-pin DIP package.
