SN74AXC8T245PWR - Texas Instruments 8-Bit Dual-Supply Bus Transceiver

The SN74AXC8T245PWR from Texas Instruments is an 8-bit non-inverting bus transceiver that is designed to operate from 0.65 V to 3.6 V, making it suitable for voltage translation applications in mixed-voltage systems. This device is part of Texas Instruments' AXC family, which is optimized for low-voltage operation that is compatible with the requirements of modern low-voltage and mixed-voltage systems.

With two voltage supply rails (V<sub>CCA and V<sub>CCB), this transceiver is capable of translating between two different logic levels. The A ports are designed to track V<sub>CCA, which accepts any supply voltage from 0.65 V to 3.6 V. The B ports are designed to track V<sub>CCB, which also accepts any supply voltage from 0.65 V to 3.6 V. This level translation capability allows for seamless communication between devices operating at different voltage levels within the same system.

The SN74AXC8T245PWR features 8 data input-output ports (A1-A8 and B1-B8), direction control (DIR), and output enable (OE) inputs, providing flexibility in directional control. When OE is low, the device transmits data from the A ports to the B ports when DIR is high, and from the B ports to the A ports when DIR is low. When OE is high, the outputs are placed in the high-impedance state, effectively disconnecting the bus lines.

Engineered for low power consumption and high-speed data transfer, the SN74AXC8T245PWR is characterized for operation from –40°C to 85°C, making it reliable across a wide range of environmental conditions. The robust design ensures minimal propagation delay, ensuring fast signal processing for critical applications.

The device comes in a TSSOP (Thin Shrink Small Outline Package) with 24 pins, denoted by the PWR suffix in its part number. This compact form factor is ideal for space-constrained applications, while providing the necessary pin configurations for complex circuit designs.

Whether it's for interfacing microprocessors, microcontrollers, or other digital systems that operate at different voltage levels, the SN74AXC8T245PWR offers a high-performance solution that is both versatile and reliable for designers and engineers.
