摘要： An off-chip driver circuit is provided which includes a pull-up device (32) disposed between an output terminal (62) and a first voltage dropping diode (34) which is connected to a first voltage supply source (VH), and a first voltage limiting circuit (38) connected to the common point (C) between the pull-up device and the voltage dropping diode (34). The off-chip driver circuit further includes an input inverter circuit (14) having an output (A) connected to the control element of the pull-up device (32). The inverter circuit is serially connected with a second voltage dropping diode (20) which is connected to the first voltage supply source (VH) and a second voltage limiting circuit (22) connected to the common point (B) between the second voltage dropping diode (20) and the inverter. First (36) and second (30) switches are also provided to short out the first (34) and second (20) voltage dropping diodes, respectively, when all circuits connected to the output terminal use a common voltage supply. A pull-down device (58) serially connected to a pass device (60) is provided between the output terminal (62) and a point of reference potential. A buffer circuit (46, 52) having an output (E) connected to the pull-down device (58) is coupled to a second voltage supply source (VDD) having a voltage significantly lower than the voltage of the first voltage supply source (VH).

摘要： A power up detection circuit is provided which includes a power supply terminal, an output terminal, an impedance device coupling the output terminal to the power supply terminal and a latch including a first inverter having a first device connected between the output terminal and a point of reference potential and a second device connected between the output terminal and the power supply terminal, the devices are designed so that subthreshold current passing through the first device is greater than the effective subthreshold current passing through the impedance device and the second device, and a second inverter including third and fourth devices which are designed so that a smaller subthreshold current passes through the third device than the subthreshold current passing through the fourth device. The power up circuit may further include a capacitor connected between the power supply terminal and gate electrodes of the first and second devices.

摘要： A built-in, i.e., on-chip, self-test system for a VLSI logic or memory module (10). A deterministic data pattern generator (80) is provided on the VLSI chip, and operates to test a chip module and provide a fail/no-fail result, along with data identifying where the fail occurred. This location data is captured and made available for subsequent utilization. The built-in test circuitry is programmable, and is provided with a looping capability to provide enhanced burn-in testing, for example.
