1 / 6 page  TLF6609 June 1989 9334DM9334 8-Bit Addressable Latch General Description The DM9334 is a high speed 8-bit Addressable Latch de- signed for general purpose storage applications in digital systems It is a multifunctional device capable of storing sin- gle line data in eight addressable latches and being a one- of-eight decoder and demultiplexer with active level high outputs The device also incorporates an active level low common clear for resetting all latches as well as an active level low enable The DM9334 has four modes of operation which are shown in the mode selection table In the addressable latch mode data on the data line (D) is written into the addressed latch The addressed latch will follow the data input with all non- addressed latches remaining in their previous states In the memory mode all latches remain in their previous state and are unaffected by the data or address inputs In the one-of-eight decoding or demultiplexing mode the addressed output will follow the state of the D input with all other inputs in the low state In the clear mode all outputs are low and unaffected by the address and data inputs When operating the device as an addressable latch chang- ing more than one bit of the address could impose a tran- sient wrong address Therefore this should only be done while in the memory mode The function tables summarize the operation of the product Features Y Common clear Y Easily expandable Y Random (addressable) data entry Y Serial to parallel capability Y 8 bits of storageoutput of each bit available Y Active high demultiplexingdecoding capability Y Alternate MilitaryAerospace device (9334) is available Contact a National Semiconductor Sales OfficeDistrib- utor for specifications Connection Diagram Dual-In-Line Package TLF6609 – 1 Order Number 9334DMQB 9334FMQB DM9334J or DM9334N See NS Package Number J16A N16E or W16A C1995 National Semiconductor Corporation RRD-B30M105Printed in U S A |
