Nexperia | 74HC259D,653

The 74HC259D 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. 7-A.

The 74HC259 are high-speed 8-bit addressable latches designed for general purpose storage applications in digital systems. They are multifunctional devices capable of storing single-line data in eight addressable latches and providing a 3-to-8 decoder and multiplexer function with active HIGH outputs (Q0 to Q7).

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
• Input levels:
  • For 74HC259: CMOS level
  • For 74HCT259: TTL level
