PIN DESCRIPTIONS

The descriptions of the pins are listed in Table 3-1.

TABLE 3-1:

PIN FUNCTION TABLES

3.1

RESET Output (RESET)

The RESET output remains low while VCC is below the

reset voltage threshold, and for 200 msec (100 msec

min.) after VCC rises above reset threshold. The output

stage of the TC1272 is complimentary, while the output

stage of the TC1273 is open-drain.

3.2

RESET Output (RESET)

The RESET output remains high while VCC is below the

reset voltage threshold, and for 200 msec (100 msec

min.) after VCC rises above reset threshold. The output

stage of the TC1274 is complimentary.
