Low-Voltage 16-Bit Bus Transceiver with 3.6-V Tolerant Inputs and Outputs

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

it achieves high-speed operation while maintaining the CMOS

low power dissipation.

up to 3.6 V.

(DIR) inputs and output enable (OE) inputs which are common to

each byte. It can be used as two 8-bit transceivers or one 16-bit

transceiver. 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.

undershoot without external resistor.

Features (Note)

•

The TC74VCXR162245FT is a high-performance CMOS 16-bit

It is also designed with overvoltage tolerant inputs and outputs

This 16 bit bus transceiver is controlled by direction control

The 26-Ω series resistor helps reducing output overshoot and

All inputs are equipped with protection circuits against static discharge.

26-Ω series resistors on all outputs

Low-voltage operation: V

High-speed operation: t

utput current: I

Latch-up performance: ±300 mA

ESD performance: Machine model > ±200 V

Package: TSSOP (thin shrink small outline package)

Bidirectional interface between 2.5 V and 3.3 V signals.

3.6-V tolerant function and power-down protection is 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.

All floating (high impedance) bus pins must have their input level fixed by means of pull-up or pull-down

resistors.
