Texas Instruments SN74AHC240/SN74AHC240-Q1 Octal Buffers/Drivers
Introduction
The Texas Instruments SN74AHC240/SN74AHC240-Q1 is a high-performance octal buffer/driver designed to enhance the efficiency and density of various electronic applications. With its robust design and AEC-Q100 qualification, it is particularly suited for automotive and other demanding environments.
Part Description
The SN74AHC240/SN74AHC240-Q1 consists of two 4-bit buffers/line drivers that feature separate output-enable (OE) inputs. When the OE\ input is low, data from the A inputs is transmitted to the Y outputs. Conversely, when OE\ is high, the outputs enter a high-impedance state, effectively disconnecting them from the circuit. This functionality makes the device ideal for applications requiring efficient data handling and signal integrity. The device boasts a low propagation delay of 4.3 ns (typical at 25°C and 5V) and excellent latch-up performance exceeding 250mA per JESD 17.
