TC74VCX162827FT

Low-Voltage 20-Bit Bus Buffer with 3.6-V Tolerant Inputs and Outputs

The TC74VCX162827FT is a high-performance CMOS 20-bit

bus buffer. 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.

The TC74VCX162827FT is composed of two 10-bit sections

with separate output-enable signals. For either 10-bit buffer

section, the two output-enable (1OE1 and 1OE2 or 2 OE1 and

2 OE2) inputs must both be low for the corresponding Y outputs

to be active. When the OE input is high, the outputs are in a

high-impedance state. This device is designed to be used with

3-state memory address drivers, etc.

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

• 26-Ω series resistors on outputs

• ESD performance: Machine model ≥ ±200 V

Human body model

≥ ±2000 V

• Package: TSSOP

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

Weight: 0.25 g (typ.)
