The TC7MPS3125FK/FTG is a dual supply, advanced

high-speed CMOS 4-bit dual supply voltage interface bus

transceiver 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-port interfaces with the 1.2-V, 1.5-V, 1.8-V or 2.5-V bus,

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

The direction of data transmission is determined by the level of

the DIR input. The enable input (OE) can be used to disable the

device so that the buses are effectively isolated. (Note1)

All inputs are equipped with protection circuits against static

discharge or transient excess voltage.

Features

? Bidirectional interface between 1.2-V and 1.8-V, 1.2-V and

2.5-V, 1.2-V and 3.3-V, 1.5-V and 2.5-V, 1.5-V and 3.3-V, 1.8-V

and 2.5-V, 1.8-V and 3.3-V or 2.5-V and 3.3-V buses.

? Output current: IOH/IOL = ±12 mA (min) (VCC = 3.0 V)

IOH/IOL = ±9mA (min) (VCC = 2.3 V)

IOH/IOL = ±3 mA (min) (VCC = 1.65 V)

IOH/IOL = ±1mA (min) (VCC = 1.4 V)

? Latch-up performance: ±300 mA

? ESD performance: Machine model ≥ ±200 V

Human body model ≥ ±2000 V

? Ultra-small package: VSSOP (US16), VQON16

? 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.

? Floating A-bus and B-bus are permitted. (when OE = “H”)

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

Note 1: Do not apply a signal to any bus pins when it is in the output mode. Damage may result.
