The 74VHC245MTC is a single-channel (8-bit) non-inverting transceiver from Fairchild's 74VHC family. It operates from 2V to 5.5V, with 8mA source/sink current per channel. The 3-State outputs and bidirectional capability make it ideal for data bus applications. Packaged in a 20-TSSOP, it is suitable for telecommunications, industrial control, and consumer electronics.
- Wide Supply Range (2V-5.5V): Works with both 3.3V and 5V logic, reducing inventory.
- Bidirectional Operation: Simplifies data bus design with direction control.
- High-Speed CMOS: Low propagation delay for high-frequency signals.
- 3-State Outputs: Enables bus sharing and isolation.
Bidirectional Bus Transceiver
Connect two data buses in a microcontroller system, allowing data transfer in both directions with direction control via the DIR pin. The 3-State outputs prevent bus conflicts.
5V/3.3V Level Translation
With a 5.5V maximum supply, this transceiver can interface 5V legacy peripherals with 3.3V controllers, simplifying mixed-voltage designs.
Data Acquisition Systems
Buffer analog-to-digital converter outputs to a digital signal processor. The high-speed 74VHC family ensures minimal data latency.
Memory Data Bus Buffering
Isolate the microcontroller's data bus from multiple memory chips, improving signal integrity and reducing capacitive loading.
Industrial Control Logic
Use in PLCs to interface between different logic modules. The wide temperature range and robust CMOS design ensure reliability.
Peripheral Expansion Boards
On Raspberry Pi or Arduino shields, this transceiver allows safe bidirectional communication with 5V sensors and actuators.
