The 74LVC245AT20-13 is a high-performance octal bus transceiver from Diodes Incorporated, designed for bidirectional asynchronous communication between data buses. Operating within a 1.65V to 3.6V supply range, it delivers 24mA of output current at both HIGH and LOW states, ensuring robust signal drive. The non-inverting 3-State outputs allow for bus isolation and multiplexing, making it ideal for memory interfacing, level shifting, and general-purpose I/O expansion in 3.3V and lower-voltage systems. Its 20-TSSOP package is compact and suitable for space-constrained PCBs.
- Wide 1.65V to 3.6V Supply Range: Compatible with 1.8V, 2.5V, and 3.3V logic, simplifying mixed-voltage designs.
- High 24mA Output Current: Drives heavy capacitive loads and long traces, maintaining signal integrity.
- 3-State Outputs: Enables bus multiplexing and isolation, preventing data contention.
- Extended Temperature Range (-40°C to 125°C): Suitable for automotive and industrial applications.
Bidirectional Bus Interfacing
Use the 74LVC245A to connect a 3.3V microcontroller data bus to a 3.3V peripheral bus. The 3-State outputs and direction control (DIR) allow seamless data flow in both directions without bus contention.
Level Shifting in Mixed-Voltage Systems
With a wide supply range of 1.65V to 3.6V, this transceiver can act as a level shifter between 1.8V and 3.3V logic domains, ensuring proper signal integrity in mixed-voltage designs.
Signal Buffering for High-Capacitance Loads
Drive long PCB traces or multiple loads with the 24mA output current capability. This buffering prevents signal degradation and maintains fast edge rates in high-speed digital systems.
Memory Address/Data Bus Isolation
Isolate the CPU bus from memory modules during power-down or reset. The 3-State outputs can be placed in high-impedance mode, preventing back-powering and protecting sensitive components.
GPIO Expansion for Microcontrollers
Expand the number of available I/O pins by using the transceiver as a bidirectional buffer. The high-impedance control (OE) allows multiple peripherals to share the same data lines.
Industrial Sensor Interfacing
Interface industrial sensors operating at 3.3V with a logic controller. The wide temperature range (-40°C to 125°C) ensures reliable operation in harsh environments.
