74ACTQ245QSCX

Buffers, Drivers, Receivers, Transceivers Overview

The onsemi 74ACTQ245QSCX is an octal bidirectional transceiver featuring non-inverting buffers with three-state outputs, designed for bus-oriented applications. It utilizes FACT Quiet Series technology to ensure quiet output switching and improved dynamic threshold performance. The device operates within a supply voltage range of 4.5V to 5.5V and supports data flow direction control via the Transmit/Receive input. Both A and B ports provide a current sinking capability of 24 mA. The component is housed in a 20-lead Quarter Size Outline Package (QSOP) and functions reliably across an operating temperature range of -40°C to +85°C.
