SN74HC14: Non-Inverting Schmitt-Trigger with clamp-diodes

Part Number: SN74HC14
Other Parts Discussed in Thread: SN74HCS125, SN74HC541, SN74HC244

Hi all

My customer is currently using the SN74HC14 to condition the input-signals for the processor. Now they have a design where they need a non-inverting device.

They are looking for a device with clamping-diodes to GND and VCC for both positive and negative currents.

Moreover they are space-limited.

Can you point to suitable devices ?

Best regards

If Schmitt-trigger inputs are required, use the SN74HCS125. Otherwise, use the SN74HC244 (eight channels) or SN74HC541 (six channels, nice pinout).

Thank you for the quick reply.

As Schmitt-Trigger inputs are required it would then be the the SN74HCS125
