3-to-8 Line Decoder

General Description

The MM74HC138 decoder utilizes advanced silicon-gate

CMOS technology and is well suited to memory address

decoding or data routing applications. The circuit features

high noise immunity and low power consumption usually

associated with CMOS circuitry, yet has speeds compara-

ble to low power Schottky TTL logic.

The MM74HC138 has 3 binary select inputs (A, B, and C).

If the device is enabled, these inputs determine which one

of the eight normally HIGH outputs will go LOW. Two active

LOW and one active HIGH enables (G1, G2A and G2B)

are provided to ease the cascading of decoders.

Ordering Code:

Devices also available in Tape and Reel. Specify by appending suffix letter “X” to the ordering code.

The decoder’s outputs can drive 10 low power Schottky

TTL equivalent loads, and are functionally and pin equiva-

lent to the 74LS138. All inputs are protected from damage

due to static discharge by diodes to V

Features

Typical propagation delay: 20 ns

Wide power supply range: 2V–6V

Low quiescent current: 80 A maximum (74HC Series)

Low input current: 1 A maximum

Fanout of 10 LS-TTL loads
