3-to-8 Line Decoder

line decoder fabricated with silicon gate C

achieves the high speed operation similar to equivalent bipolar

schottky TTL while maintaining the CMOS low power

dissipation.

determine which one of the outputs (Y0 - Y7) will go low.

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.

V to 5 V system.

without regard to the supply voltage. These structure prevents device destruction due to mismatched supply and

input/output voltages such as battery back up, hot board insertion, etc.

Features

•

The TC7MET138AFK is an advanced high speed CMOS 3-to-8

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

The input voltage are compatible with TTL output voltage.

This device may be used as a level converter for interfacing 3.3

Input protection and output circuit ensure that 0 to 5.5 V can be applied to the input and output

Note: V

High speed: t

Low power dissipation: I

Compatible with TTL outputs: V

Power down protection is provided on all inputs and outputs.

Balanced propagation delays: t

Pin and function compatible with the 74 series (74AC/HC/ALS/LS etc.) 138 type.
