Product Summary

The NTE74HC245 is a high−speed octal 3−state bidirectional transceiver in a 20−lead DIP-type package intended for two−way asynchronous communication between data buses. It contains high-drive current outputs which enable high−speed operation while driving large bus capacitances. It also provides the low-power consumption of standard CMOS circuits with speeds and drive capabilities comparable to that of LS−TTL circuits. The NTE74HC245 allows data transmission of the B BUS or from the B BUS to the A BUS. The logic level at the direction input (DIR) determines the direction. The output enable input (OE), when high, puts the I/O ports in the high-impedance state.

  • Wide-power supply range: 2V to 6V
  • High-noise immunity: NIL = 30%, NIH = 30% of VCC at VCC = 5V
  • 3−state outputs
  • Buffered inputs
  • BUS line driving capability
  • High−current BUS driver outputs
  • Fanout (over temp range): standard outputs 10 LS−TTL loads, BUS driver outputs 15 LS−TTL loads
  • Balanced propagation delay and transition times
  • Significant power reduction compared to LS−TTL logic ICs
