MC74HC238A

MC74HC238A 1-of-8 Decoder/ Demultiplexer High−Performance Silicon−Gate CMOS The MC74HC238A is identical in pinout to the LS238. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LSTTL outputs. The HC238A decodes a three−bit Address to one−of−eight active−high 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 V to 6.0 V Low Input Current: 1.0 mA High Noise Immunity Characteristic of CMOS Devices In Compliance with the Requirements Defined by JEDEC Standard No. 7A Chip Complexity: 100 FETs or 29 Equivalent Gates NLV Prefix for Automotive and Other Applications Requiring Unique Site and Control Change Requirements; AEC−Q100 Qualified and PPAP Capable These are Pb−Free Devices* www.onsemi.com 16 1 MARKING DIAGRAMS 16 SOIC−16 D SUFFIX CASE 751B HC238AG AWLYWW 1 16 16 1 TSSOP−16 DT SUFFIX CASE 948F HC 238A ALYWG G 1 A WL, L Y WW, W G or G = Assembly Location = Wafer Lot = Year = Work Week = Pb−Free Package (Note: Microdot may be in either...
