Part Number: SN74AHCT541 Other Parts Discussed in Thread: SN74HCT541 , CD74HCT541 , CD74ACT541 , SN74LV541AT Hello.
I want to replace SN74AHCT541 with SN74LVC541APW.
VCC is 5V.
The data sheet states that the recommended voltage is up to 3.6V…
The RGY and RKS packages are not compatible.
The SN74LVC541A and SN74LV541AT are available in the RGY package, but have different supply voltage ranges.
For unidirectional signals, use a unidirection translator like the TXU0104.
For translation from 3.3 V to 5 V, you can also use a buffer with TTL-compatible inputs, e.g., SN74AHCT244/SN74LV244AT/SN74AHCT541/SN74LV541AT.
The SN74LV541A is not a level shifter; you cannot use it to convert from 3.3 V to 5 V.
The SN74ABT541 is designed to have TTL-compatible inputs and outputs, and the high-level voltage of TTL signals is near 3.4 V.
To be able to convert from 3.3 V…
3.3 V happens to be the TTL output voltage, so you can use buffers with TTL-compatible inputs like the SN74AHCT541 or SN74LV541AT.
There are single-supply level shifters with lowered switching thresholds at the inputs like the SN74LV4T125. They do not…
Hi Chase,
Please see the answer provided by Sebastian to your previous post here: SN74LV541AT: Difference Between SN74LV541ATRGY vs SN74LV541ARGYR
It would also be helpful if you could mark that post (and this one) as resolved. Please let us know…
The SN74LV541AT has all these characteristics, except that it is non-inverting.
The only device with the same pinout is the SN74ABT540, but its outputs also have TTL levels (i.e., a lower high level).
In a different pinout, you could use 2× SN74LV4T125;…
Questions about the SN74LV541ATRGYR:
1) The table at the end of the datasheet suggests the operating temperature range for this package is up to 85C. Is this the max ambient air temp?
2) The theta_ja for this package looks the best of all the available…
