Regarding the part SN74HCS138PWR, what does HCS mean? Does it stand for a certain technology?
Could you please kindly explain the meaning or share with us its nomenclature?
Thanks.

Part Number: SN74HCS138 I am planning to turn on SN74HCS138 using MSP432P4111 GPIO pin i.e. give 3.3V as Vcc to the demux from a GPIO pin of my controller. I will be using multiple demuxes in a way that I can turn on and off each device using the controller…
More modern devices in the HCS family (SN74HCS125, SN74HCS138, SN74HCS541) are specified for 125 °C. The major difference from HC is that they have Schmitt-trigger inputs.
Hi Kazuhiro-san,
For our HC devices, since they are relatively old, unfortunately we do not have the models for some of these. The best I can offer is the HCS IBIS model: https://www.ti.com/product/SN74HCS138 which should be very similar in performance…
The "T" indicates a device with TTL-compatible inputs, and TTL runs only at 5 V.
When you go outside the recommended operating conditions, neither the electrical characteristics nor correct operation are guaranteed. Use the SN74HCS138-Q1 instead…
Part Number: SN3257-Q1 Other Parts Discussed in Thread: TMUX1309 , , SN74HCS138 , SN74HCS151 As shown in the figure below, whether SN3257 can implement this topology, please help to confirm
CD4000 devices cannot output 50 mA. And the CD4059A has a single output pin.
You need a counter that outputs all 16 states, like the SN74LV163A. To convert that binary number into 16 individual signals, use decoders, e.g., 2x SN74HCS138. To drive the…
