TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic

TC74VCX138FT, TC74VCX138FK

Low Voltage 3-to-8 Line Decoder with 3.6 V Tolerant Inputs and Outputs

The TC74VCX138 is a high performance CMOS 3-to-8 decoder

which is guaranteed to operate from 1.2-V to 3.6-V. Designed for

use in 1.5 V, 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 over voltage tolerant inputs and

outputs up to 3.6 V.

When the device is enabled, 3 binary select inputs (A, B and C)

determine which one of the outputs (Y0 - Y0) will go low.

When enable input G1 is held low or either G2A or G2B is held

high, decoding function is inhibited and all outputs go high.

G1, G2A and G2B inputs are provided to ease cascade

connection and for use as an address decoder for memory

systems.

All inputs are equipped with protection circuits against static

discharge.

Features

• 3.6 V tolerant inputs and outputs.

• Latch-up performance: −300 mA

• ESD performance: Machine model ≥ ±200 V

Human body model

≥ ±2000 V

• Package: TSSOP and VSSOP (US)

• Power down protection is provided on all inputs and outputs.
