The 74VHCT126ATTR from STMicroelectronics is an advanced high-speed CMOS quad bus buffer. It utilizes sub-micron silicon gate and double-layer metal wiring C2MOS technology. The device requires the 3-STATE control input G to be set low to place the output in the high impedance state.
Key electrical characteristics include a high-speed operation with a typical propagation delay of 3.8 ns at VCC = 5V and low power dissipation with a maximum ICC of 2 µA at 25°C. The inputs are compatible with TTL outputs, featuring VIH of 2V (min) and VIL of 0.8V (max). It offers symmetrical output impedance with IOH = IOL = 8 mA (min) and balanced propagation delays (tPLH ≅ tPHL).
This buffer provides power down protection on inputs and outputs, and can accept 0 to 7V on inputs regardless of the supply voltage, making it suitable for interfacing 5V to 3V systems. All inputs and outputs are equipped with protection circuits against static discharge, providing 2KV ESD immunity.
The 74VHCT126ATTR is supplied in a 14-TSSOP surface mount package. It operates over a temperature range of -55°C to 125°C (TA).
