SLVS087M – DECEMBER 1994 – REVISED MARCH 2012

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

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.
