74LVQ125SJ

Overview

The onsemi 74LVQ125SJ is a low voltage quad buffer with three-state outputs, housed in a 14-lead Small Outline Package (SOP) measuring 5.3mm wide. It operates within a supply voltage range of 2.0V to 3.6V and supports an operating temperature from -40°C to +85°C. The device features four independent non-inverting buffers. Key electrical characteristics include a maximum quiescent supply current of 40µA at 3.6V. Propagation delay ranges from 1.0ns to 14.0ns depending on voltage and temperature. Output drive capabilities reach ±12mA, while dynamic output currents are specified at 36mA minimum and -25mA maximum.
