Texas Instruments SN74LVC8T245PW is a high-speed 8-bit dual‑supply bus transceiver in a compact TSSOP‑24 package. Built for bidirectional voltage-level translation between voltage domains (from 1.65 V to 5.5 V), it delivers reliable performance for modern mixed-voltage systems. It outperforms generic translators by combining Ti's heritage reliability with practical features demanded by engineers in telecom, industrial control, and embedded system design.

Product Unique Features

  • Voltage Translation Range: 1.65 V to 5.5 V on both VCCA and VCCB rails.
  • Channels / Data Width: 8‑bit non‑inverting bus transceiver.
  • Output Current (High/Low): 32 mA each.
  • Logic Outputs: 3‑state outputs, supports partial‑power‑down with Ioff to prevent back‑flow currents.
  • Propagation Delay: ~4.2 ns, supporting data‑rates up to 500 Mb/s.
  • Operating Temp: –40 °C to +85 °C.
  • Package: 24‑pin TSSOP (Surface Mount).
  • Protection Properties: Partial‑power‑down (Ioff), VCC isolation (Hi‑Z when either rail is GND), high ESD immunity, latch‑up resistance.

What Benefits Does It Offer to Users?

  • Robust Voltage-Level Translation: Seamlessly connects different voltage domains, ideal for mixed-voltage systems, IoT modules, or interface buffers.
  • High-Drive Capability & Speed: 32 mA drive per direction and sub-5 ns delay ensure crisp signal integrity for fast bus communication.
  • Protected and Reliable Design: Partial power-down features support, VCC isolation, and strong ESD/latch-up resilience, making it ideal for harsh industrial or telecom environments.
  • Compact and Efficient Package: TSSOP‑24 footprint saves board space for dense PCBs and embedded designs.
