74ABT2244CSCX

Buffers, Drivers, Receivers, Transceivers Overview

The onsemi 74ABT2244CSCX is an octal buffer and line driver featuring integrated 25 Ω series resistors in the outputs. It operates within a supply voltage range of +4.5V to +5.5V. The device provides non-inverting logic with three-state outputs controlled by active-low OE inputs. Propagation delays are specified at 1.0 ns minimum and 3.9 ns maximum at 25°C, extending to 4.4 ns maximum across the industrial temperature range. Output drive capabilities include -32 mA high state current and 15 mA low state current.
