ATF750C(L)
The ATF750C(L)’s registers are provided with circuitry to allow loading of each register asyn-
chronously with either a high or a low. This feature will simplify testing since any state can be
forced into the registers to control test sequencing. A V
ter high; a V
by placing a 10.25V to 10.75V signal on pin 8 on DIPs, and lead 10 on SMDs. When the clock
term is pulsed high, the data on the I/O pins is placed into the register chosen by the select pin
.
