SN74HCS259 8-Bit Addressable Latches with Schmitt-Trigger Inputs

1 Features

• Wide operating voltage range: 2 V to 6 V

• Schmitt-trigger inputs allow for slow or noisy input

signals

• Low power consumption

– Typical input leakage current of ±100 nA

• ±7.8-mA output drive at 6 V

• Extended ambient temperature range: –40°C to

2 Applications

• Memory device selection with shared data bus

• Reduce required number of outputs for chip select

applications

• Route data

3 Description

The SN74HCS259 8-bit addressable latches are

designed for general-purpose storage applications in

digital systems. Specific uses include working

registers, serial-holding registers, and active-high

decoders or demultiplexers. They are multifunctional

devices capable of storing single-line data in eight

addressable latches and being a 1-of-8 decoder or

demultiplexer with active-high outputs.
