74ABT2244CSJX

Buffers, Drivers, Receivers, Transceivers Overview

The onsemi 74ABT2244CSJX 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 enable inputs (OE1, OE2). Propagation delay ranges from 1.0 ns to 4.4 ns at VCC = 5V with CL = 50pF. Output drive capabilities include -32 mA high state current and 15 mA low state current. It utilizes a 20-lead Small Outline Package (SOP) in tape and reel format.
