74259 IC 8-bit addressable latch
EGP18.00
Description
74259 IC 8-bit addressable latch
The 74259 is an 8-bit addressable latch from XBLW. It is designed for use in electronic circuits that require the storage of multiple binary data values. This integrated circuit features eight data latches that can be individually addressed, making it ideal for managing a range of electronic components. The device offers a high degree of flexibility in addressing, which makes it well-suited for applications in consumer electronics, communication systems, and computing hardware.
Features:
- Combined demultiplexer and 8-bit latch.
- Serial-to-parallel capability.
- Output from each storage bit available.
- Random (addressable) data entry.
- Easily expandable.
- Common reset input.
- Useful as a 3-to-8 active HIGH decoder.
- Specified from -20°C to +85°C.
