Has anyone used the TC4049BP hex buffer converter chip as an alternative to open collector NPN transistor COR inverters. I'm curious because we use such a chip with our RLC-4 controller and it works flawlessly. This chip has 6 input/outputs with a reference common voltage. There is another chip which is a buffer and it is ideal when the COR voltage requirement is higher than can be supplied by the radio COR circuit.
The chip number is TC4050BP. Of course a TC4049BP can be used as a buffer by hooking up 2 input ouputs in series.
Here is the pinout:
Pin 1 ref voltage up to 20Vcc.
Pin 8 Ground ref.
Pin 3 input / pin 2 output.
Pin 5 input / pin 4 output.
Pin 7 input / pin 6 output.
Pin 9 input / pin 10 output.
Pin 11 input / pin 12 output.
Pin 14 input / pin 15 output.
Pin 13 and 16 no
connection.
Happy new year everyone.
