Product Description

This device features a single buffer/gate with a 3-state output, which can be controlled by the output enable (OE) input. When OE is low, the device passes the input (A) to the output (Y). When OE is high, the output is in a high-impedance state, effectively disconnecting the output from the bus. This allows for the connection of multiple outputs to a bus without the risk of contention.

The 74HCT1G126GW is fabricated using silicon gate CMOS technology, ensuring high speed and reduced power consumption. Its 5V tolerant inputs allow for direct interfacing with TTL levels, while its low power consumption makes it suitable for battery-operated devices. The device also includes protection on all inputs to protect against static discharge, giving it enhanced durability in demanding environments.

With its robust design and versatile functionality, the NXP 74HCT1G126GW is an excellent choice for designers who require a reliable and efficient solution for buffering and interfacing in their digital systems.
