SN74ABT2240ADBR TI Buffer/Driver | 20-SSOP | 8-ch, Inverting, 3-State

Product Overview

The SN74ABT2240ADBR is a high-performance octal buffer and line driver from Texas Instruments, designed with 3-state outputs and inverting logic. It operates from a 4.5V to 5.5V supply, featuring 8 channels in a compact 20-SSOP package. This device is ideal for driving heavily loaded buses and capacitive loads, offering high drive capability (up to 64 mA sink/32 mA source) and fast propagation delays (typical 4.6 ns). The 3-state outputs allow for connection to a bus-oriented system without loading the bus when disabled.
