“SN74HC541 is a wide range CMOS device that can be used over large voltage ranges. The device can be used anywhere from 2 V to 6 V. The device can drive up to 6 mA of current at 5 V. This makes it perfect for driving bus lines directly or up to 15 LSTTL Loads. It can be used to drive anything from microcontrollers and system logic devices to LEDs.”

• Eight Buffers: Inputs A1–A8 are non-inverting; outputs Y1–Y8 follow the inputs when enabled.
• 3-State Control: Two enable pins, OE1 and OE2, gate outputs into three states:
  • Enabled (OE low): outputs drive inputs.
  • Disabled (OE high): outputs go high-impedance, allowing bus sharing.
• Drive Capability: ±6 mA per output at VCC=5 V.

• Bus Driving & Isolation: Buffering address/data buses in microprocessor systems.
• Level Buffering: Isolating CMOS logic from TTL loads (up to 15 LSTTL loads).
• LED Driving: Directly driving indicator LEDs or small loads.
• Signal Fan-Out Expansion: Increasing the number of loads a single logic source can drive.

• Wide Supply Voltage: 2 V–6 V operation.
• 3-State Outputs: Enables multiple devices on a shared bus.
• High Fan-Out: Up to 15 LSTTL loads at 5 V.

• Series: SNx4HC541 (74HC logic family – high-speed CMOS)
