The TC74VHCT126AF(K.F) is a high-speed CMOS quad bus buffer gate fabricated with silicon gate CMOS technology. This device features independent enable inputs, allowing for flexible control of data flow. It combines the speed of bipolar logic with the low power consumption of CMOS technology. It is commonly employed in applications requiring buffering or driving signals.

Applications:

• Bus buffering
• Line driving
• Address buffering
• Clock driving
• Data isolation

Features:

• High-speed operation: tpd = 4.9 ns (typ.) at VCC = 5 V
• Low power dissipation: ICC = 4 μA (max.) at Ta = 25 °C
• TTL input compatible: VIL = 0.8 V (max.); VIH = 2.0 V (min.)
• Output drive capability: 10 LSTTL loads
• Symmetrical output impedance: |IOH| = IOL = 4 mA (min.)
• Balanced propagation delays: tPLH ≈ tPHL
• Wide operating voltage range: VCC = 4.5 V to 5.5 V

Benefits:

• Improved system performance thanks to fast propagation delays.
• Reduced power consumption leads to increased energy efficiency.
• TTL-compatible inputs enable seamless integration with TTL logic.
• Sufficient output drive ensures reliable signal transmission.
• Balanced propagation delays simplify timing design.
• Versatile operating voltage caters to diverse system requirements.

The TC74VHCT126AF(K.F) features four independent bus buffer gates, each with its own enable input (OE). When OE is low, the output is enabled, and the input signal passes through to the output. When OE is high, the output is disabled and goes to a high-impedance state. It is designed to operate within a supply voltage range of 4.5V to 5.5V and is packaged in an SOP package. The TTL-compatible inputs make it well-suited for interfacing with TTL logic.
