TC7SPN3125TU

Low Voltage/Low Power 1-Bit Dual Supply Bus Buffer

The TC7SPN3125 is a dual supply, advanced high-speed

CMOS 1-bit dual supply voltage interface bus buffer fabricated

with silicon gate CMOS technology.

It is also designed with over voltage tolerant inputs and

outputs up to 3.6 V.

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

or 2.5-V bus and a 1.8-V, 2.5-V or 3.6-V bus in mixed 1.2-V, 1.5-V,

1.8-V or 2.5-V/1.8-V, 2.5-V or 3.6-V supply systems.

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

the B-output with the 1.8-V, 2.5-V, 3.3-V bus.

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

the signal lines are effectively isolated.

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.

• Latch-up performance: -300 mA

• ESD performance: Machine model ≥ ±200 V

Human body model

≥ ±2000 V

• Ultra-small package: UF6

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

Suitable for battery-driven applications such as PDAs and cellular phones.

• 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.
