SN74HC125DBRG4 Quad Buffer/Line Driver from Texas Instruments

The SN74HC125DBRG4 is a high-performance, quad buffer/line driver designed and manufactured by Texas Instruments (TI), a leader in semiconductor solutions. This integrated circuit is part of the 74HC family, which is known for its high-speed CMOS technology. It is specifically tailored to deliver reliable buffering with the capability to drive bus lines or buffer memory address registers.

The device features four independent non-inverting buffer/line drivers with 3-state outputs. Each buffer has its own output-enable (OE) input, which, when high, puts the respective output into a high-impedance state. This 3-state feature allows for connection to a bus-oriented system, providing a means to send a signal to multiple destinations or to isolate the bus completely.

The SN74HC125DBRG4 operates over a wide voltage range from 2V to 6V and is optimized for use in systems that require low power consumption and high noise immunity. This makes it suitable for interfacing with TTL levels and ideal for use in a variety of applications, including driving bus lines, buffering memory address registers, and as input/output port expanders.

Key features of the SN74HC125DBRG4 include:

• Wide Operating Voltage Range: 2V to 6V
• High-Current Outputs Drive Up To 15 LSTTL Loads
• Low Power Consumption: 80-µA Maximum ICC
• Typical tpd = 13 ns
• ±6-mA Output Drive at 5 V
• Low Input Current of 1 µA Maximum
• 4 Independent Buffers with 3-State Outputs
• Available in DBRG4 Tape and Reel Packaging

With its robust design, the SN74HC125DBRG4 is characterized for operation from -40°C to 85°C, ensuring performance in a wide range of environmental conditions. The device is available in a 14-pin SSOP (DBRG4) package, which is suitable for automated surface-mount assembly processes and compact PCB layouts.

Whether you're designing a microprocessor or microcontroller interface, or you need a reliable buffer for data transmission lines, the SN74HC125DBRG4 from Texas Instruments is a versatile and dependable choice that combines performance with practicality.
