Micron R/C will be closed for the Christmas/New Year break from Monday 18th December through Tuesday 2nd January. The last day for posting before Christmas will be Saturday 16th December. Orders may be processed sporadically during the close but we cannot guarantee that any order placed after 4pm on Friday 18th December will be dispatched before Wednesday 3rd January.

FET Switch Buffers

These open-drain FET buffer modules are intended for converting Deltang receiver 'P' outputs to type 'F'. The 'P' output is 0V when OFF and 3V when ON and can supply a maximum of 20mA on Rx6 receivers. Some receivers (e.g. Rx65 have 'F' outputs which provide a 'switch to ground' circuit with a 2A capability.

Most of the Rx6 receivers (Rx60, Rx61, etc) have no 'F' outputs. This creates a problem if you need to control 12V light bulbs or trigger a sound module. Many sound modules have more than 3V on the trigger input and this could damage the receiver microprocessor. The solution is to use one of these tiny add-on modules.

The buffer input connects to the 'P' output and the load is wired in-between the buffer output and the load positive supply, which can be up to 30V. Although designed for use with Deltang land-based receivers, these FET switches can be used where a low-level logic signal is required to switch a high current / high voltage load.
