Manufacturer:TI Description:Other inputs to the SN54HC20J include a Watchdog Detec- tor (WDI) and 4 General Purpose Inputs (GPIn). The Watchdog Detector can be used to monitor a processor clock. If the clock does not toggle (transition from low to high or from high to low) within a programmable timeout period (up to 18 sec.), a fail flag will assert. The 4 Gen- eral Purpose inputs can be configured as logic buffers or to detect positive/negative edges and to generate a logic pulse or level from those edges. Thus, the user can input control signals from other parts of their system (eg RE- SET or POWER_GOOD) to gate the sequencing of the supplies supervised by the SN54HC20J. |
