74LVT125PW,112

Overview

The Nexperia 74LVT125PW,112 is a quad buffer and line driver featuring three-state outputs controlled by active LOW output enable inputs (nOE). It operates within a supply voltage range of 2.7 V to 3.6 V and utilizes BiCMOS technology for high-speed performance. The device provides an output capability of +64 mA and -32 mA, ensuring robust signal driving. Inputs are overvoltage tolerant up to 5.5 V, allowing direct interfacing with TTL levels. Bus hold data inputs eliminate the need for external pull-up resistors for unused inputs. The component includes IOFF circuitry for partial power-down applications, preventing damaging backflow currents.
