74HC540 Octal Inverting Buffer/Line Driver/Line Receiver
Octal buffer/line driver/line receiver with versatile compatibility and high noise immunity.
- Output Drive Capability: 15 LSTTL Loads
- Operating Voltage Range: 2.0 to 6.0 V
- Low Input Current: 1 A
- High Noise Immunity Characteristic of CMOS Devices
The 74HC540 is identical in pinout to the LS540, featuring inputs compatible with Standard CMOS outputs and external pull-up resistors for LSTTL compatibility. It is designed for use with 3-state memory address drivers, clock drivers, and bus-oriented systems, with inputs and outputs positioned on opposite sides of the package and two ANDed active-low output enables.
