74HC540 - Octal Buffers and Line Drivers

General Description

These octal buffers and line drivers feature the performance of the popular ’HC240 series and offer a pinout with inputs and outputs on opposite sides of the package.

This arrangement greatly facilitates printed circuit board layout.

The 3-state control gate is a 2-input NOR.

Key Features

  • Wide operating voltage range of 2 V to 6 V.
  • High-current 3-state outputs drive bus lines directly or up to 15 LSTTL loads.
  • Low power consumption, 80-μA max ICC.
  • Typical tpd = 8 ns.
  • ±6-mA output drive at 5 V.
  • Low input current of 1 μA max.
  • Data flow-through pinout (all inputs on opposite side from outputs) 2.
