NXP 74HC259D 8-Bit Addressable Latch SOIC16
NXP 74HC259D 8-bit addressable latch in SOIC16 package. Features 74HC logic, 2 V to 6 V supply range and 25 mA output current.
The NXP 74HC259D 8-Bit Addressable Latch is an 8-bit addressable latch in an SOIC16 package, supporting 74HC logic with a 2 V to 6 V supply range and 25 mA output current.
Overview
This integrated circuit provides four modes of operation for a range of digital design applications. In addressable latch mode, data present at the D input is written into the specific latch selected by the A0 to A2 address inputs. The selected latch follows the data input while non-addressed latches retain their previous states, allowing random data entry. In memory mode, all latches hold their data independent of changes on the address or data lines.
Decoding and Reset
In 3-to-8 decoding or demultiplexing mode, the addressed output follows the D input while all other outputs are forced low. A common reset input forces all outputs low regardless of other inputs.
Key Features
- Inputs with clamp diodes, enabling current-limiting resistors to interface with signals exceeding the VCC supply voltage
- Serial-to-parallel conversion capability, with output available from each individual storage bit
- Expandable design for wider data paths
- Complies with JEDEC standard No. 7A for CMOS input levels
- Fabricated with high-speed CMOS technology for low power consumption and high noise immunity
Package and Dimensions
The SOIC16 package is designed for efficient PCB space utilisation and is suitable for automated assembly processes. Dimensions are 3.3 (width), 1.5 (depth) and 4.3 (height), with a product weight of 0.001 g.
