We're looking for the 4ch buffer with VCC=5V, and the Input Voltage is from MCU 3.3V.
It looks SN74HCS125 is able to meet this…
Hello Clemens,
When using SN74HCS125 - can we use multi channles in parallel to increase the effective capacitive drive strength?
We have to interface TMP144 sensors to our MCU UART & we are planning to use the SN74HCS125 (already in inventory) for improved…
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.
1. This specification applies to all inputs.
2. Oscillations at the outputs, or even damage; see [FAQ] How does a slow or floating input affect a CMOS device?
Consider using a device with Schmitt-trigger inputs, i.e., the SN74HCS125 instead.
Hello @Ren,
No, not at the moment, we plan to run these cables separately. My primary concern is the potential noise interference in an industrial setting and its impact on device operation. We are incorporating suitable ESD, EFT, and Surge protection…
Hello Clemens Ladisch ,
Thank you for your as always crisp, to the point & insightful feedback & suggestions.
We had another question for you, when trying to maintain the Signal integrity of the SPI signals over 1/2m cables, how well can buffers…
The average data rate does not matter; what is the SPI clock frequency?
Just using single-ended signals with buffers (e.g., SN74LVC125A, SN74HCS125) at both ends is possible. But if you expect a noisy environment or a ground shift between the two boards…
Other Parts Discussed in Thread: AM26C31 , AM26C32 , CD4050B , SN74HCS125 , THVD2450V Hello Community,
We're working on a project that involves transmitting a 32kHz clock signal from a MEMS TXO (SIT1552AC-JE-DCC-32.768E) to a remote MEMS Accelerometer via…
Mark Philip Felipe said: 1.) Can you send me the full spice model netlist for other HCS circuits below including the .SUBCKT line and ENDS? The spice netlist below is missing some information.
Sure - there are many available on TI.com -- one example is…
Hi Gerald,
We do not have any device with 6 independent buffers. Our best suggestion is to use two SN74HCS125 which has 4 independent buffers.
Best, Albert
