Key Features
- Four modes of operation: addressable latch, memory, 3-to-8 decoding/demultiplexing, and reset.
- Data on the D input is written into the latch addressed by inputs A0 to A3 in addressable latch mode.
- All latches retain their previous states in memory mode.
- In 3-to-8 decoding/demultiplexing mode, the addressed output follows the D input while other outputs are LOW.
- All outputs are forced LOW in reset mode.
- Inputs include clamp diodes for interfacing with voltages in excess of VCC.
