SN74AHCT125N Quad Bus Buffer Gate from Texas Instruments

The SN74AHCT125N is a high-performance, quad bus buffer gate that features non-inverting outputs designed by Texas Instruments. This integrated circuit is part of the 'AHCT' family, which is known for its advanced high-speed CMOS technology. The SN74AHCT125N is particularly suitable for driving bus lines or buffer memory address registers due to its high drive current and low power consumption.

Each of the four buffers has a separate output-enable (OE) input that, when high, disables the output by placing it in a high-impedance state. This feature is crucial for preventing bus contention. Moreover, the device is capable of translating inputs from 5V down to 3.3V, making it compatible with a wide range of logic levels and suitable for mixed-voltage applications.

The SN74AHCT125N operates over a broad voltage range from 4.5V to 5.5V, providing a flexible power supply requirement. This allows the device to integrate seamlessly into various digital systems without the need for additional level-shifting hardware. The device also features a typical t<sub>pd (propagation delay time) of 8.5ns with a low power consumption of 10µA max ICC.

The package of the SN74AHCT125N is a standard 14-pin DIP (Dual In-line Package), which is widely used and easy to handle in various types of PCB designs. This makes it a versatile choice for prototyping as well as mass production. The operating temperature range of the device is from -40°C to 85°C, which ensures reliable operation under extreme conditions.

Texas Instruments' SN74AHCT125N is a reliable choice for designers looking for a quad bus buffer with high drive capability and low power consumption. Its compatibility with mixed-voltage systems and ease of use make it an ideal choice for a wide array of applications, including bus drivers, memory drivers, and buffer memory address registers in digital systems.
