The HD74ACT125FPEL is a Quadruple Bus Buffer Gate with 3-State Outputs manufactured by Renesas Electronics America. It is part of the Advanced CMOS Technology (ACT) logic family, offering a combination of high-speed performance and low power consumption. The 3-state outputs enable the device to be isolated from the bus when not actively driving, facilitating shared bus architectures.

• Low power consumption reduces overall system power requirements
• TTL compatible inputs allow for easy interfacing with TTL logic devices

Technical Specifications

The HD74ACT125FPEL contains four independent buffer gates. Each gate has an output enable (OE) input. When OE is low, the buffer is enabled, and the output follows the input. When OE is high, the output is in a high-impedance (Z) state, effectively disconnecting the buffer from the output. The device is designed for operation over a wide voltage range, typically 4.5V to 5.5V. The inputs are TTL compatible, ensuring proper operation with TTL logic levels. The propagation delay from input to output is typically in the nanosecond range. The HD74ACT125FPEL is usually packaged in a small outline package (SOP).
