Nexperia 74AHCT245 Bus Transceivers

Nexperia 74AHCT245 Bus Transceivers are high-speed Si-gate CMOS devices with an Output Enable (OE) and send/receive (DIR) for direction control. These 8-bit octal bus transceivers are designed to operate over a VCC range from 4.5V to 5.5V. The Nexperia 74AHCT245 bus transceiver inputs are TTL compatible, which allows the device to translate from 3.3V to 5V. The Schmitt-trigger action at all inputs makes the circuit tolerant of slower input rise and fall times.

Features

  • Balanced propagation delays
  • All inputs have Schmitt-trigger actions
  • Inputs accept voltages higher than VCC
  • Input levels
    • For 74AHC245: CMOS level
    • For 74AHCT245: TTL level
  • Multiple package options
  • ESD protection
    • HBM EIA/JESD22-A114E exceeds 2000V
    • MM EIA/JESD22-A115-A exceeds 200V
    • CDM EIA/JESD22-C101C exceeds 1000V
  • Specified from -40°C to 85°C and from -40°C to 125°C temperature range
