The HD74HC541FPEL-E is an octal buffer/line driver with three-state outputs manufactured by Renesas Electronics America. This high-speed CMOS device utilizes silicon gate CMOS technology to achieve high-speed operation similar to equivalent Bipolar Schottky TTL, while maintaining low power dissipation. The HD74HC541FPEL-E is particularly useful for driving highly capacitive loads or low-impedance lines.

Applications

• Memory address drivers
• Clock drivers
• Bus-oriented applications
• Data transmission
• Peripheral drivers

Features

• High-speed operation: tpd = 13 ns (typ.) at VCC = 5V
• Low power dissipation: ICC = 4 μA (max.) at Ta = 25°C
• High output drive capability: 15 LSTTL loads
• Symmetrical output impedance: |IOH| = IOL = 6 mA (min.)
• Wide operating voltage range: VCC = 2 to 6 V
• Three-state outputs
• Pin and function compatible with 74LS541

Benefits

• Improved system performance due to high-speed operation.
• Reduced power consumption, leading to energy efficiency.
• High drive capability for driving multiple loads or long lines.
• Flexible operating voltage range suitable for various applications.
• Provides isolation between circuits when the output is disabled.
• Easy replacement of existing 74LS541 devices.

Additional Details

The HD74HC541FPEL-E has two active-low output enable inputs (OE1 and OE2). When either OE1 or OE2 is HIGH, the outputs are in the high-impedance state. This allows multiple devices to share the same bus. The device is supplied in a 20-pin SOP (Small Outline Package).

Absolute Maximum Ratings: Supply Voltage (VCC): -0.5 to +7.0 V, DC Input Voltage (VI): -0.5 to VCC + 0.5 V, DC Output Voltage (VO): -0.5 to VCC + 0.5 V, Operating Temperature (Topr): -40 to +85 °C.
