SN74HCT240 - OCTAL BUFFERS AND LINE DRIVER

Description

These octal buffers and line drivers are designed specifically to improve both the performance and density of 3-state memory address drivers, clock drivers, and bus-oriented receivers and transmitters.

Features

  • Operating voltage range of 4.5 V to 5.5 V.
  • High-current outputs drive up to 15 LSTTL loads.
  • Low power consumption, 80-μA max ICC.
  • Typical tpd = 12 ns.
  • ±6-mA output drive at 5 V.
  • Low input current of 1 μA max.
  • Inputs are TTL-voltage compatible.
  • 3-state outputs drive bus lines or buffer memory address registers 2.
