Popular PIC Products PIC Handheld Programmer PIC 8-Way Handheld Programmer USB PIC Programmer PIC Portable Programmer WebFor any logic family, there are a number of threshold voltage levels to know. Below is an example for standard 5V TTL levels: V OH-- Minimum OUTPUT Voltage level a TTL device will provide for a HIGH signal. V IH-- Minimum INPUT Voltage level to be considered a HIGH. V OL-- Maximum OUTPUT Voltage level a device will provide for a LOW signal.

WebIf the chip and programming board are configured for “high-voltage programming”, then 11.5 V is used instead of ground (0 V) to signal reset. Because microcontroller pins are connected to much lower voltages in projects, the standard 0 V to 5 V signals will not cause a reset, and that pin can be used for input and output.
