74ABT2240CSC

Buffers, Drivers, Receivers, Transceivers Overview

The onsemi 74ABT2240CSC is an octal buffer and line driver belonging to the ABT logic family. It features inverting outputs with integrated 25Ω series resistors designed to reduce signal ringing. The device operates within a supply voltage range of +4.5V to +5.5V and supports free air ambient temperatures from -40°C to +85°C. Propagation delays are typically 4.9ns for high-to-low transitions and 5.3ns for low-to-high transitions at VCC=5V. It provides guaranteed latchup protection and maintains high impedance during power-up and power-down cycles.
