MC74HC138A datasheet

 

Description :

The MC74HCT138A is identical in pinout to the LS138. The 74HCT138A may be used as a level converter for interfacing TTL or  NMOS outputs to High Speed CMOS inputs.
The 74HCT138A decodes a three−bit Address to one−of−eight active−lot outputs. This device features three Chip Select inputs, two active−low and one active−high to facilitate the demultiplexing, cascading, and chip−selecting functions. The demultiplexing function is accomplished by using the Address inputs to select the desired device output; one of the Chip Selects is used as a data input while the other Chip Selects are held in their active states.

Features :

1. Output Drive Capability: 10 LSTTL Loads

2. Outputs Directly Interface to CMOS, NMOS and TTL

3. Operating Voltage Range: 2.0 to 6.0 V

4. Low Input Current: 1.0 μA

5. High Noise Immunity Characteristic of CMOS Devices
