74HC540

The 74HC540 is a high-speed CMOS octal buffer/line driver featuring non-inverting 3-state outputs. It is designed to improve both the performance and density of 3-state memory address drivers, clock drivers, and bus-oriented receivers and transmitters. Each of the eight buffers/drivers has its own output enable (OE) input for controlling the output states, making it suitable for driving bus lines or buffering memory address registers in digital systems.

Key Features:

• Eight non-inverting buffers/drivers
• 3-state outputs for bus-oriented applications
• Individual output enable (OE) inputs for each buffer
• High-speed CMOS technology
• Low power consumption
• High noise immunity
• TTL-compatible inputs
• Wide supply voltage range: 2V to 6V

Technical Specifications:

• Supply Voltage (VCC): 2V to 6V
• Input Voltage Range: 0V to VCC
• High-Level Output Voltage (VOH): VCC – 0.1V (min at VCC = 4.5V)
• Low-Level Output Voltage (VOL): 0.1V (max at VCC = 4.5V)
• High-Level Input Voltage (VIH): 70% of VCC (min)
• Low-Level Input Voltage (VIL): 30% of VCC (max)
• Propagation Delay Time: 13 ns (typical at VCC = 5V)
• Operating Temperature Range: -40°C to +85°C
• Package: 20-pin DIP, SOIC, TSSOP

Applications:

• Bus drivers for data buses in microprocessor systems
• Memory address drivers in digital circuits
• Clock drivers for distributing clock signals
• Data buffers to prevent signal degradation
• Transmitters and receivers in bus-oriented systems
