TC74VCXR162646FT

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

The TC74VCXR162646FT is a high-performance CMOS 16-bit

bus transceiver/register. 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.

It is also designed with overvoltage tolerant inputs and outputs

up to 3.6 V.

This device is bus transceiver with 3-state outputs, D-type

flip-flops, and control circuitry arranged for multiplexed

transmission of data directly from the internal registers.

The 26-Ω series resistor helps reducing output overshoot and

undershoot without external resistor.

All inputs are equipped with protection circuits against static

discharge.

Features (Note)

• 26-Ω series resistors on outputs

• Latch-up performance: −300 mA

• ESD performance: Machine model ≥ ±200 V

Human body model

≥ ±2000 V

• Package: TSSOP

• Bidirectional interface between 2.5 V and 3.3 V signals.

• 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.

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

resistors.

Weight: 0.25 g (typ.)
