SN74HCT541DWRG4 Octal Buffer/Line Driver with 3-State Outputs
The SN74HCT541DWRG4 from Texas Instruments is a high-performance, octal buffer and line driver designed to interface with 5V systems. This integrated circuit features eight non-inverting buffers with 3-state outputs, making it an ideal choice for driving bus lines or buffer memory address registers. The device is part of the HCT family, which is specifically designed to operate at 4.5V to 5.5V, providing a robust and compatible interface with TTL logic levels.
Each buffer of the SN74HCT541DWRG4 has a corresponding output-enable (OE) input, which, when held high, places the output in a high-impedance state. This feature allows for multiple devices to be connected to the same bus line, which is a common requirement in complex digital systems. The 3-state outputs also enable the device to be used in bus-organized systems, where data flow is required in both directions without bus contention.
Manufactured with Texas Instruments' advanced silicon-gate CMOS technology, the SN74HCT541DWRG4 offers the high-speed operation of traditional TTL circuits while maintaining the low power consumption of CMOS technology. This makes it suitable for interfacing with microprocessors, microcontrollers, and other logic systems that require high-speed, low-power operation.
The SN74HCT541DWRG4 comes in a wide-body SOIC package, which is designated by the suffix 'DW'. The 'RG4' suffix indicates that this device is compliant with RoHS requirements, making it suitable for use in environmentally sensitive applications. With a temperature range of -40°C to 85°C, the device is reliable across various operating conditions.
Key features of the SN74HCT541DWRG4 include:
- Compatible with TTL inputs
