Features

•

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

It is also designed with over voltage tolerant inputs and

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

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

G1, G2A and G2B inputs are provided to ease cascade

All inputs are equipped with protection circuits against static

Low voltage operation: V

High speed operation: t

3.6 V tolerant inputs and outputs.

Output current: I

Latch-up performance: −300 mA

ESD performance: Machine model ≥ ±200 V

Package: TSSOP and VSSOP (US)

Power down protection is provided on all inputs and outputs.
