The MM74HCT540WM from Elantec is an octal inverting buffer designed for 4.5V to 5.5V operation. It provides 8 channels of signal inversion with 3-State outputs and 7.2mA drive capability. The 74HCT logic family ensures TTL compatibility, making it ideal for 5V systems. Housed in a 20-SOIC package, it is suitable for industrial controls, LED driving, and legacy bus interfacing.
- TTL-Compatible Inputs: Directly interfaces with 5V TTL logic without level shifting.
- 3-State Outputs: Provides bus isolation and prevents contention.
- Inverting Buffer: Combines buffering and inversion in one device.
- Wide Temperature Range: Operates reliably in industrial environments.
- Standard 5V Operation: Compatible with legacy and current 5V systems.
5V Bus Isolation
Isolate microcontroller buses from peripheral devices. The 3-State outputs allow disconnecting the buffer when not in use.
Inverting LED Drivers
Drive active-low LED indicators. The 7.2mA sink current directly powers LEDs with current-limiting resistors.
Legacy 5V System Interfacing
Interface with older 5V TTL logic. The 74HCT family's TTL-compatible inputs ensure seamless integration.
Memory Address Buffering
Buffer address lines in 5V memory systems. The inverting function can be used for active-low chip selects.
Industrial Sensor Readout
Buffer sensor outputs with inversion. The wide temperature range (-40°C to 85°C) suits factory automation.
Test and Measurement
Provide inverted, buffered signals for bench equipment. The 3-State feature enables multiple test points sharing a bus.
