Description
Key features include a wide supply voltage range, typically operating from 2.7V to 3.6V, and the capability to interface with 5V TTL logic levels, making it versatile for various applications. The 74LVT245MTC is known for its high-speed operation, low power consumption, and the ability to sink/source a substantial amount of current, allowing it to drive heavy loads.
The device is typically housed in a 20-pin TSSOP (Thin Shrink Small Outline Package), which aids in reducing board space. It is commonly used in applications requiring data buffering, bus interfacing, and signal integrity maintenance across digital systems.

Features
1. Bi-directional Communication: Allows data flow in both directions between buses.
2. 3-State Outputs: Can be set to high, low, or high-impedance state for multiple bus connections.
3. Low Voltage Operation: Operates at 3.3V but is compatible with 5V systems.
4. High-Speed Performance: Provides fast data transmission suitable for high-speed operations.
5. Bus-Hold Inputs: Eliminates the need for external pull-up or pull-down resistors by maintaining the last known state.
6. Low Power Consumption: Designed to be energy efficient while maintaining performance.
7. Latch-Up Protection: Withstands high current surges, providing robustness.
8. Small Form Factor: Available in a TSSOP package, suitable for space-constrained applications.
These features make the 74LVT245MTC suitable for applications requiring fast data transfer, low power, and reliable bus communication.
Pinout
- Pin Count: 20 pins
- Function: This device is an octal bus transceiver with 3-state outputs, meaning it can transmit data in both directions on a bus and can be set to a high-impedance state to effectively disconnect it from the bus when not in use.
Pin Functions:
- Pins 2-9: Data I/O pins (D0-D7)
- Pins 11-18: Data I/O pins (Q0-Q7)
- Pin 1: Direction control (DIR) - Determines the direction of data flow.
- Pin 19: Output enable (OE) - Active low; when low, the device can drive the bus.
- Pin 20: VCC - Power supply
- Pin 10: GND - Ground
The 74LVT245MTC supports a wide range of operating conditions and is suited for level shifting and buffering applications in digital systems.
