SNJ54AHCT126W Quad Bus Buffer Gates with 3-State Outputs

The SNJ54AHCT126W from Texas Instruments is a high-performance, four-line buffer gate featuring 3-state outputs designed to drive bus lines or buffer memory address registers. This integrated circuit is part of the AHCT family, which is characterized by its advanced high-speed CMOS technology, combining the speed of HC with the drive capabilities of ACT.

Each buffer gate has a separate output-enable (OE) input that, when high, puts the output into a high-impedance state. This feature allows for the disconnection of the output from the bus line, providing a means to implement bus arbitration or memory sharing, where multiple devices can take turns driving a common bus line without interference.

The SNJ54AHCT126W comes in a robust ceramic flat package, ensuring high durability and reliability even under extreme environmental conditions. This makes it suitable for military or aerospace applications that require stringent quality levels and extended operational temperature ranges. The device is also compatible with TTL levels, facilitating easy interfacing with older logic families.

• Logic Type: Quad Bus Buffer, 3-State
• Output Type: 3-State
• Operating Temperature Range: Military-grade with a wide range from -55°C to 125°C
• Supply Voltage: 4.5V to 5.5V, typical 5V
