Additional Details

The TC7WG125FC is housed in a fine-pitch small outline package (FC package), which is designed for high-density surface mounting. The device operates over a wide temperature range, making it suitable for a variety of environments. The supply voltage range typically is from 1.65V to 5.5V, offering flexibility in system design.

The output enable (OE) input controls the 3-state output, allowing the device to be enabled or disabled. When disabled, the output is in a high-impedance state, effectively disconnecting the device from the bus. This allows multiple devices to share the same bus lines without contention. This IC Complies with industry standards for RoHS compliance and lead-free manufacturing.
