SN74AHC240N TI Buffer/Driver | 20-PDIP | 8-Ch, 2V to 5.5V

Product Overview

The SN74AHC240N is a high-performance octal buffer and line driver from Texas Instruments, designed for 2-V to 5.5-V VCC operation. It features 3-state outputs and is ideal for driving bus lines or buffer memory address registers. The device is organized as two 4-bit buffers/drivers with separate output-enable (OE) inputs. When OE is low, the outputs are enabled; when high, the outputs are in the high-impedance state. The inputs are tolerant to up to 5.5 V, allowing down-translation to VCC. The SN74AHC240N is offered in a 20-pin PDIP package, making it suitable for through-hole PCB assembly.
