74ABT646CMSAX

Buffers, Drivers, Receivers, Transceivers Overview

The onsemi 74ABT646CMSAX is an octal bus transceiver and register with 3-state outputs, manufactured in a 24-lead Shrink Small Outline Package (SSOP). It operates within a supply voltage range of 4.5V to 5.5V and supports data rates up to 200 MHz. The device features independent registers for A and B buses, allowing multiplexed real-time and stored data transmission. Key electrical characteristics include a maximum propagation delay of 5.6 ns at 50 pF load, output sink capability of 64 mA, and source capability of 32 mA. It ensures guaranteed output skew and simultaneous switching noise levels.
