74VHC(T)245

Octal bus transceiver; 3-state

The 74VHC245; 74VHCT245 are high-speed Si-gate CMOS devices.

The 74VHC245; 74VHCT245 are octal transceivers featuring non-inverting 3-state bus compatible outputs in both send and receive directions.

The 74VHC245; 74VHCT245 feature an output enable input (OE), for easy cascading, and a send and receive direction control input (DIR).

OE controls the outputs so that the buses are effectively isolated.

Features

  • Balanced propagation delays
  • All inputs have Schmitt-trigger action
  • Inputs accept voltages higher than VCC
  • Input levels:
    • The 74VHC245 operates with CMOS input level
    • The 74VHCT245 operates with TTL input level
  • ESD protection:
    • HBM JESD22-A114E exceeds 2000 V
    • MM JESD22-A115-A exceeds 200 V
    • CDM JESD22-C101C exceeds 1000 V
  • Multiple package options
  • Specified from -40 °C to +85 °C and from -40 °C to +125 °C
