8-bit Addressable Latch - Nxp Semiconductors

The 74AHC/AHCT259 are high-speed Si-gate CMOS devices and are pin compatible with Low power Schottky TTL (LSTTL). They are specified in compliance with JEDEC standard No. 7A. The 74AHC/AHCT259 are high-speed 8-bit addressable Latches designed for general purpose storage applications in digital systems. The 259 are multifunctional devices capable of storing single-line data in eight addressable Latches and also 3-to-8 decoder and demultiplexer, with active HIGH outputs (Q0 to Q7), functions are available. The 259 also incorporates an active LOW common reset (MR) for resetting all Latches as well as an active LOW enable input (LE). The 259 has four modes of operation as shown in the mode select 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 states and are unaffected by the data or address inputs. By NXP Semiconductors
