74ACT11240DBR

Buffers, Drivers, Receivers, Transceivers Overview

The Texas Instruments 74ACT11240DBR is an octal buffer and line driver featuring three-state outputs. It utilizes the EPIC (Enhanced-Performance Implanted CMOS) process to deliver high fan-out and improved fan-in capabilities. The device operates within a supply voltage range of 4.5 V to 5.5 V, with a typical operating current of 80 µA at 5.5 V. It provides symmetrical active-low output-enable inputs and inverting outputs. The component supports operation from -40°C to +85°C and includes center-pin VCC and GND configurations to minimize high-speed switching noise.
