Specific uses include working registers, serial-holding registers, and decoders or demultiplexers. This is a multifunctional device capable of operating as eight addressable latches or an 8-line demultiplexer with active-low DMOS outputs. Each open-drain DMOS transistor features an independent chopping current-limiting circuit to prevent damage in the case of a short circuit. Four distinct modes of operation are selectable by controlling the clear (CLR) and enable (G) inputs as enumerated in the function table. In the addressable-latch mode, data at the data-in (D) terminal is written into the addressed latch. The addressed DMOS-transistor output inverts the data input with all unaddressed DMOS-transistor outputs remaining in their previous states. In the memory mode, all DMOS-transistor outputs remain in their previous states and are unaffected by the data or address inputs. To eliminate the possibility of entering erroneous data in the latch, enable G should be held high (inactive) while the address lines are changing. In the 8-line demultiplexing mode, the addressed output is inverted with respect to the D input and all other outputs are high. In the clear mode, all outputs are high and unaffected by the address and data inputs. Separate power ground (PGND) and logic ground (LGND) terminals are provided to facilitate maximum system flexibility. All PGND terminals are internally connected, and each PGND terminal must be externally connected to the power system ground in order to minimize parasitic impedance. A single-point connection between LGND and PGND must be made externally in a manner that reduces crosstalk between the logic and load circuits. 1 20 2 19 3 18 4 17 5 16 6 15 7 14 8 13 9 12 10 11 DRAIN1 DRAIN0 S0 VCC PGND PGND CLR D DRAIN7 DRAIN6 DW PACKAGE (TOP VIEW) DRAIN2 DRAIN3 S1 LGND PGND PGND PGND PGND S2 G DRAIN4 DRAIN5 1 24 2 23 3 22 4 21 5 20 6 19 7 18 8 17 9 16 10 15 11 14 12 13 DRAIN1 DRAIN0 S0 VCC PGND PGND PGND PGND CLR D DRAIN7 DRAIN6 FUNCTION TABLE INPUTS CLR H H H L L L G D L H L L H X L L H H L X OUTPUT OF ADDRESSED DRAIN L H Qio L H H EACH OTHER DRAIN Qio Qio Qio H H H FUNCTION Addressable Latch Memory 8-Line Demultiplexer Clear LATCH SELECTION TABLE SELECT INPUTS S2 S1 S0 L L L L L H L H L L H H H L L H L H H H L H H H DRAIN ADDRESSED 0 1 2 3 4 5 6 7 Copyright 1995, Texas Instruments Incorporated PRODUCTION DATA information is current as of publication date.
