74F240SJX

Buffers, Drivers, Receivers, Transceivers Overview

The onsemi 74F240SJX is an octal buffer and line driver featuring inverting logic with three-state outputs. It operates within a supply voltage range of +4.5V to +5.5V. The device provides high drive capability, sinking up to 64 mA and sourcing 12 mA. Propagation delays are specified at a maximum of 8.0 ns under standard conditions. Input clamp diodes are integrated to limit high-speed termination effects. The component is housed in a 20-lead Small Outline Package (SOP) with the 'X' suffix indicating tape and reel packaging.
