Octal bus transceiver; 3-state

The 74LV245 is a low-voltage Si-gate CMOS device that is pin and function compatible with 74HC245 and 74HCT245.

The 74LV245 is an octal transceiver with non-inverting 3-state bus compatible outputs in both send and receive directions. A send/receive (DIR) input controls direction, and an output enable (OE) input makes easy cascading possible. Pin OE controls the outputs so that the buses are effectively isolated.


  • Wide operating voltage: 1.0 V to 5.5 V
  • Optimized for low voltage applications: 1.0 V to 3.6 V
  • Accepts TTL input levels between VCC = 2.7 V and VCC = 3.6 V
  • Typical output ground bounce < 0.8 V at VCC = 3.3 V and Tamb = 25 °C
  • Typical HIGH-level output voltage (VOH) undershoot: > 2 V at VCC = 3.3 V and Tamb = 25 °C
  • ESD protection:
    • HBM JESD22-A114E exceeds 2000 V
    • MM JESD22-A115-A exceeds 200 V
  • Multiple package options
  • Specified from -40 °C to +85 °C and from -40 °C to +125 °C
