MM74HCT240WMX

The MM74HCT240WMX from On Semiconductor is a high-speed inverting buffer utilizing advanced silicon-gate CMOS technology. It features 3-state outputs, making it suitable for connection to system buses. This buffer is designed for high drive current outputs, enabling fast operation even with large bus capacitances, achieving speeds comparable to low-power Schottky devices while maintaining CMOS low power consumption.

Key electrical characteristics include a supply voltage range of 4.5V to 5.5V and an operating temperature range of -40°C to 85°C. The device has a typical propagation delay of 14 ns and a minimum output drive current of 6 mA. It is TTL input compatible and has a fanout of 15 LS-TTL equivalent inputs. The MM74HCT240WMX is intended for interfacing between TTL and NMOS components and standard CMOS devices, serving as a plug-in replacement for LS-TTL devices to reduce power consumption.

This component is supplied in a 20-SOIC surface mount package with dimensions of 0.295 inches (7.50mm) width. It features two independent active low enables, each controlling four buffers. All inputs are protected against static discharge damage by diodes to VCC and ground.
