Part Number : MC74HC138A
Function : 1-of-8 Decoder / Demultiplexer with LSTTL Compatible Inputs
Package : DIP, SOIC, TSSOP 16 Pin Type
Maker : ON Semiconductor
Pinouts :
Description :
The 1-of-8 Decoder / Demultiplexer is identical in pinout to the MC74HC138A.
The MC74HCT138A 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
• Output Drive Capability: 10 LSTTL Loads
• Outputs Directly Interface to CMOS, NMOS and TTL
• Operating Voltage Range: 2.0 to 6.0 V
• Low Input Current: 1.0 A
• High Noise Immunity Characteristic of CMOS Devices
