The 74HCT240PW is a dual inverting buffer from the 74HCT family, featuring 3-state outputs. It operates from 4.5V to 5.5V, making it ideal for 5V TTL-compatible systems. Each channel provides 6mA drive current, suitable for bus interfacing and signal conditioning. The 20-TSSOP package is compact for high-density boards, and the wide temperature range supports industrial and automotive applications.
- TTL-Compatible Inputs: Directly interfaces with 5V TTL logic without extra level shifting.
- Inverting Function: Provides signal inversion where needed, reducing external inverter ICs.
- 3-State Outputs: Enables bus sharing and isolation in multi-device 5V systems.
- Extended Temperature Range: -40°C to 125°C ensures reliability in automotive and industrial settings.
5V TTL Bus Inverting Buffer
The 74HCT240PW inverts and buffers signals on 5V buses, ensuring proper logic levels in TTL-based systems.
Memory Address Inversion
It inverts address lines for memory decoding schemes, simplifying PCB layout in retro-computing projects.
Peripheral Isolation in 5V Systems
3-state outputs isolate peripherals from the main bus during power-up or standby, preventing glitches.
Industrial Sensor Interfacing
With a -40°C to 125°C range, it buffers inverted sensor signals in harsh industrial environments.
Signal Conditioning for Legacy Logic
It converts non-inverted signals to inverted form for compatibility with legacy ICs requiring active-low inputs.
Automotive ECU Signal Buffering
In automotive ECUs, it buffers and inverts control signals for actuators, operating reliably at high temperatures.
