The MC74LCX240DTR2 is a low-voltage CMOS octal buffer designed for operation within a supply voltage range of 1.65 to 5.5 V. It features inverting outputs and is compatible with 5 V TTL logic, allowing for safe interfacing with 5 V devices. The device supports live insertion and withdrawal, making it suitable for various applications, including memory address driving and TTL level bus-oriented transceiver applications. This buffer has a high impedance TTL-compatible input that minimizes current loading on input drivers, while its outputs can drive up to 24 mA at 3 V. The output enable (OE) input allows for disabling the outputs by placing them in a high impedance state. The device exhibits near-zero static supply current in all three logic states, significantly reducing overall system power requirements. Additionally, it has robust ESD performance, withstanding voltages greater than 2000 V according to the Human Body Model. The MC74LCX240DTR2 is available in a TSSOP-20 package and is RoHS compliant.
