the signal lines are effectively isolated.

Features

•

The TC7SP3125 is a dual supply, advanced high-speed CMOS

It is also designed with over voltage tolerant inputs and

Designed for use as an interface between a 1.2-V, 1.5-V, 1.8-V,

The A-input interfaces with the 1.2-V, 1.5-V, 1.8-V or 2.5-V bus,

The enable input (OE) can be used to disable the device so that

All inputs are equipped with protection circuits against static discharge or transient excess voltage.

Level converter for interfacing 1.2-V to 1.8-V, 1.2-V to 2.5-V, 1.2-V to 3.3-V, 1.5-V to 2.5-V, 1.5-V to 3.3-V, 1.8-V

to 2.5-V, 1.8-V to 3.3-V or 2.5 V to 3.3-V system.

High-speed operation : t

Output current : I

Latch-up performance: -300 mA

ESD performance: Machine model ≥ ±200 V

Ultra-small package: UF6

Low current consumption : Using the new circuit significantly reduces current consumption when OE = “H”.

3.6-V tolerant function and power-down protection provided on all inputs and outputs.

Note: Do not apply a signal to any bus pins when it is in the output mode. Damage may result.
