SN54HC640 - OCTAL BUS TRANSCEIVERS

Description

The SNx4HC640 is an octal bus transceiver with 3state outputs.

All eight channels are controlled by the direction (DIR) pin and output enable OE pin.

Features

  • Wide operating voltage range of 2V to 6V.
  • High-Current 3-state outputs can drive up to 10 LSTTL loads.
  • Low power consumption, 80-µA max ICC.
  • Typical tpd = 8ns.
  • ±4-mA output drive at 5V.
  • Low input current of 1µA max.
  • Inverting logic 2.
