Low-Voltage Octal Bus Transceiver with 3.6 V Tolerant Inputs and Outputs

The TC7MAR2245FK is a high performance CMOS octal bus

transceiver. Designed for use in 1.8, 2.5 or 3.3 V systems, it

achieves high speed operation while maintaining the CMOS low

power dissipation.

It is also designed with over voltage tolerant inputs and

outputs up to 3.6 V.

The direction of data transmission is determined by the level of

the DIR inputs. The OE inputs can be used to disable the device

so that the busses are effectively isolated.

The 26-Ω series resistor helps reducing output overshoot and

undershoot without external resistor.

Weight: 0.03 g (typ.)

All inputs are equipped with protection circuits against static

discharge.

Features

•

26-Ω series resistors on outputs.

Low voltage operation: V

= 1.8~3.6 V

High speed operation:

= 3.0~3.6 V)

= 2.3~2.7 V)

= 1.8 V)

= 5.6 ns (max) (V

= 9.8 ns (max) (V

•

3.6 V tolerant inputs and outputs.

Output current:I /I = ±12 mA (min) (V

= 3.0 V)

OH OL

= ±8 mA (min) (V

= ±4 mA (min) (V

= 2.3 V)

= 1.8 V)

OH OL

•

Latch-up performance: −300 mA

ESD performance:Machine model ≥ ±200 V

Human body model ≥ ±2000 V

Package: VSSOP (US)

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

*2: All floating (high impedance) bus terminal must have their input level fixed by means of pull up or pull down

resistors.

*3: To ensure the high-impedance state during power up or power down, OE should be tied to V

through a

pullup resistor; the minimum value of the resistor is determined by the current-sourcing capability of the driver.
