[Ideas For Design]
Minimize clock-to-output delays in CPLD designs
Minimizing clock-to-output (tco) delays in a CPLD-based design may permit use of a slower, lower-cost CPLD. The example design shown is a state-machine implemented using a CPLD that operates as an interface between a memory-mapped...  — Contributing Author

[Ideas For Design]
Circuit senses high-side current from negative supply
The circuit shown monitors the flow of load current into a negative voltage source (Fig. 1). This requirement often arises in private branch exchanges, in ISDN power supplies, when monitoring supply currents...  — Contributing Author

[Ideas For Design]
Keyboard scanner provides system supervision
The circuit shown scans a numeric keypad while also generating 16-ms timing interrupts, low-line resets, and power-fail warnings for a larger system (see the figure). The core of the circuit is a versatile...  — Contributing Author
