These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.
DESCRIPTION (CONTINUED)
In addition to the power-on-reset and undervoltage-supervisor function, the TLC77xx adds power-down control
support for static RAM. When CONTROL is tied to GND, RESET will act as active high. The voltage monitor
contains additional logic intended for control of static memories with battery backup during power failure. By
driving the chip select (CS) of the memory circuit with the RESET output of the TLC77xx and with the CONTROL
driven by the memory bank select signal (CSH1) of the microprocessor (see Figure 10), the memory circuit is
automatically disabled during a power loss. (In this application the TLC77xx power has to be supplied by the
battery.)
The TLC77xxI is characterized for operation over a temperature range of –40°C to 85°C; the TLC77xxQ is
characterized for operation over a temperature range of –40°C to 125°C; and the TLC77xxM is characterized for
operation over the full Military temperature range of –55°C to 125°C.
The 3x3 mm DRB package is also available as a non-magnetic package for medical imaging application.
