Overview

High-Performance Silicon-Gate CMOS

The MC74HC540A is identical in pinout to the LS540. The device inputs are compatible with Standard CMOS outputs. External pullup resistors make them compatible with LSTTL outputs.

The HC540A is an octal inverting buffer/line driver/line receiver designed to be used with 3-state memory address drivers, clock drivers, and other bus-oriented systems. This device features inputs and outputs on opposite sides of the package and two ANDed active-low output enables.

The HC540A is similar in function to the HC541A, which has non-inverting outputs.

  • Output Drive Capability: 15 LSTTL Loads
  • Outputs Directly Interface to CMOS, NMOS and TTL
  • Operating Voltage Range: 2 to 6V
  • Low Input Current: 1mA
  • High Noise Immunity Characteristic of CMOS Devices
  • In Compliance With the JEDEC Standard No. 7A Requirements
  • Chip Complexity: 124 FETs or 31 Equivalent Gates
  • Pb-Free Packages are Available*
