74ACTQ245SJ

Buffers, Drivers, Receivers, Transceivers Overview

The onsemi 74ACTQ245SJ is an octal bidirectional transceiver featuring non-inverting buffers with three-state outputs. It utilizes FACT Quiet Series/G165 technology to ensure quiet output switching and improved dynamic threshold performance. The device operates within a supply voltage range of 4.5 V to 5.5 V, supporting TTL-compatible inputs. It provides a current sinking capability of 24 mA at both A and B ports. The component is housed in a Pb-Free 20-Lead Small Outline Package (SOP), EIAJ TYPE II, measuring 5.3 mm wide.
